Serrador (es), Ignacio Casal Quinteiro (gl), Takeshi AIHANA (ja), Theppitak Karoonboonyanan (th) 2.13.2 == This release just contains a merge of all the changes on the constraints_experiments branch. Thanks to Havoc Pennington for reviewing the gargantuan patch and suggesting lots of little fixes for making it better, to Rob Adams and Soeren Sandmann for grilling me on how some of the difficult internals work -- allowing me to improve the documentation, to Olav Vitters for finding an easy-to-fix crasher bug in early testing and for repeatedly extending my deadline for switching from working on Metacity to Bugzilla, to Ray Strode for finding two crashers and fixing one of them in early testing, to Bryan Clark for usability advice, to Davyd Madeley and Christian Kellner for testing Xinerama stuff, to Sebastien Bacher for packaging an early version and finding some obscure bugs (that I unfortunately still can't duplicate and will probably still need to fix once I can), Bugs fixed: unfiled - constraints.c is overly complicated[1] unfiled - constraints.c is not robust when all constraints cannot simultaneously be met (constraints need to be prioritized) unfiled - keep-titlebar-onscreen constraint is decoration unaware (since get_outermost_onscreen_positions() forgets to include decorations) unfiled - keyboard snap-moving and snap-resizing snap to hidden edges 86644 - resize should have a shift option like move does 109553 - gravity w/ simultaneous move & resize doesn't work 113601 - maximize vertical and horizontal should toggle and be constrained 122196 - windows show up under vertical panels 122670 - jerky/random resizing of window via keyboard[2] 124582 - keyboard and mouse snap-resizing and snap-moving erroneously moves the window multidimensionally 136307 - don't allow apps to resize themselves off the screen (*cough* filechooser *cough*) 142016, 143784 - windows should not span multiple xineramas unless placed there by the user 143145 - clamp new windows to screensize and force them onscreen, if they'll fit 144126 - Handle pathological strut lists sanely[3] 149867 - fixed aspect ratio windows are difficult to resize[4] 152898 - make screen edges consistent; allow easy slamming of windows into the left, right, and bottom edges of the screen too. 154706 - bouncing weirdness at screen edge with keyboard moving or resizing 156699 - avoid struts when placing windows, if possible (nasty a11y blocker) 302456 - dragging offscreen too restrictive 304857 - wireframe moving off the top of the screen is misleading 308521 - make uni-directional resizing easier with alt-middle-drag and prevent the occasional super annoying resize-the-wrong-side(s) behavior 312007 - snap-resize moves windows with a minimum size constraint 312104 - resizing the top of a window can cause the bottom to grow 319351 - don't instantly snap on mouse-move-snapping, remove braindeadedness of having order of releasing shift and releasing button press matter so much [1] fixed in my opinion, anyway. [2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major code changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges. These get updated with the workarea in src/workspace.c:ensure_work_areas_validated() Translation Michiel Sikkes (nl) 2.13.1 == Thanks to Philip O'Brien, Kjartan Maraas, and Aidan Delaney for improvements in this release. - add handling for META_PREF_CURSOR_THEME and META_PREF_CURSOR_SIZE for more complete debug info (Philip) [#318976] - Remove possible g_source leak in #ifdef'd out code, in case anyone uses it in the future (Kjartan) [#320050] - Changed the 'minimized' field of the MetaTabEntry struct to 'hidden' (Aidan) [#168455] Translations Miloslav Trmac (cs), Francisco Javier F.

Rather it is meant as just a brief overview of some of the bigger structures and files, with guides for a variety of task categories providing places to start looking in the code and things to look for. Overview Jobs of various files Major data structures and their relationships Getting started -- where to look Jobs of various files src/window.c is where all the guts of the window manager live. This is basically the only remotely scary file. src/frames.c is the GtkWidget that handles drawing window frames. src/core.h defines the interface used by the GTK portion of the window manager to talk to the other portions. There's some cruft in here that's unused, since nearly all window operations have moved out of this file so frameless apps can have window operations. src/ui.h defines the interface the plain Xlib portion of the window manager uses to talk to the GTK portion. src/theme.c and src/theme-parser.c have the theme system; this is well-modularized from the rest of the code, since the theme viewer app links to these files in addition to the WM itself. Major data structures and their relationships Major structs have a "Meta" prefix, thus MetaDisplay, MetaScreen, MetaWindow, etc. This serves as a way of namespacing in C. It also has the side effect of avoiding conflicts with common names that X already uses such as Display, Screen, Window, etc. Note that when I refer to a display below, I'm meaning a MetaDisplay and not a Display. Don't confuse displays and screens. While Metacity can run with multiple displays, it is kind of useless since you might as well just run two copies of Metacity. However, having multiple screens per display is useful and increasingly common (known as "multiscreen" and "xinerama" setups, where users make use of more than one monitor). You should basically think of a display as a combination of one or more monitors with a single keyboard (...and usually only one mouse). There is also a significant difference between multiscreen and xinerama as well. Basically, each MetaScreen is a root window (root node in the tree of windows). With Xinerama, a single root window appears to span multiple monitors, whereas with multiscreen a root window is confined to a single monitor. To re-emphasize the distinction between a display and a screen, the pointer and keyboard are shared between all root windows for a given display. The display keeps track of a lot of various global quantities, but in particular has a compositor and a list (GList) of screens. A compositor is an opaque structure (only defined in compositor.c), meaning that you'll only reference the API for it. It handles (or will handle) cool stuff with the new X extensions, such as smooth resizing and alpha transparency. A screen keeps track of a number of quantities as well, in particular a stack and a list of workspaces. A stack is basically a list of windows, and the depth order they have relative to each other (which thus determines which windows are on top and which are obscured). A workspace mostly contains a list of windows for the workspace, but also has a few other quantities as well (a list of struts which are areas where windows should not be placed and an mru_list or "most recently used window list"). A window has a huge list of quantities for keeping track of things about a window on the screen. (We want to avoid making this list larger because the memory for all these quantities is per window.) One item in particular that a window has, though, is a frame. A frame is the decorations that surround the window (i.e. the titlebar and the minimize and close buttons and the part that you can use to resize), and contains a handful of variables related to that, but no other major structures. Getting started -- where to look Getting started on developing free software projects can often be like being dropped off in a town that is unknown to you and being told to make a map, when various road and building signs are missing or fading. To try to alleviate that initial difficulty in orientation, below I list a variety of general task categories with file, function, variable, and x property names that may be useful to fixing bugs or writing features that fall within that category. First, though, it's useful to note that most event and message passing goes through display.c:event_callback(), so that's often a good place to start reading for general familiarity with the code (actually, I'd suggest skipping down to the first switch statement within that function). Of course, not all events go through that function, as there are a few other places that handle events too such as frames.c. Anyway, without further ado, here are the categories and (hopefully) useful things to look at for each: Focus issues (i.e. issues with which window is active): doc/how-to-get-focus-right.txt meta_workspace_focus_default_window _NET_ACTIVE_WINDOW _NET_WM_USER_TIME meta_window_focus meta_display_(set_input|focus_the_no)_focus_window XSetInputFocus (only for purposes of understanding how X focus/input works) CurrentTime (mostly, you should just think "Bad; don't use it") Compositor stuff (X extension for eye candy like transparency): compositor.c The luminocity module in CVS Window depth (i.e. stacking or lowering/raising) issues: stack.c _NET_CLIENT_LIST_STACKING transient_for WM_TRANSIENT_FOR meta_window_(raise|lower) _NET_WM_WINDOW_TYPE _NET_WM_MOUSE_ACTION/_NET_WM_TAKE_ACTIVITY? (aren't yet in EWMH) Window placement issues: place.c constraints.c _NET_WM_STRUT WM_SIZE_HINTS Moving and resizing issues: constraints.c update_move update_resize meta_window_handle_mouse_grab_op_event _NET_MOVERESIZE_WINDOW _NET_WM_STRUT Drag and drop issues: the XDND protocol (see http://www.newplanetsoftware.com/xdnd/ and http://freedesktop.org/Standards/XDND) _NET_WM_MOUSE_ACTION/_NET_WM_TAKE_ACTIVITY (aren't yet in EWMH) A general pointer: what causes the difficulty here is that when the application receives a mouse click to start a drag, it does a grab so that the window manager doesn't get any further events; thus correcting things require standards so that applications and window managers can collaborate correctly Theme issues: ??? doc/theme-format.txt theme.c theme-parser.c (ui.c, core.c, frames.c, frame.c? I dunno...) Session management issues: ??? session.c http://www.x.org/X11R6.8.1/doc/SM/xsmp.pdf ? http://www.x.org/X11R6.8.1/doc/SM/SMlib.pdf ? meta_window_apply_session_info Tasklist and Workspace switcher issues: window-props.c various functions in screen.c (especially ones using XChangeProperty) xprops.c The libwnck module in cvs meta_window_client_message Lots of the EWMH Window and workspace selection/changing issues: tabpopup.c keybindings.c, functions: *_workspace*, *_tab_* meta_screen_ensure_*_popup display.c, functions: *_tab* Key and mouse binding actions: keybindings.c meta_frames_button_(press|release)_event display.c: event_callback, but only the (Key|Button)_(Press|Release) cases Xinerama and multiscreen: ???

There are multiple versions of the theme format, and a given theme can support more than one format. Version 1: THEMEDIR/metacity-1/metacity-theme-1.xml (original metacity format) Version 2: THEMEDIR/metacity-1/metacity-theme-2.xml Version 3: THEMEDIR/metacity-1/metacity-theme-3.xml The subdirectory name is "metacity-1" in all versions. As you might expect, older versions of metacity will not understand newer theme formats. However, newer versions will use old themes. Metacity will always use the newest theme format it understands that the X server supports. Some format versions are only supported if you have the right X server features. Each format *requires* the corresponding filename. If you put version 2 format features in the metacity-1/metacity-theme-1.xml file, then metacity will get angry. This document has separate sections for each format version. You may want to read the document in reverse order, since the base features are discussed under version 1. New Features in Theme Format Version 3.4 ======================================== An additional color type is added to pick up custom colors defined in the GTK+ theme's CSS: gtk:custom(name,fallback) where refers to a custom color defined with @define-color in the GTK+ theme, and provides an alternative color definition in case the color referenced by is not found. New Features in Theme Format Version 3.3 ======================================== Add two additional button background functions - left_single_background and right_single_background - for button groups with just a single button. There are now additional frame states to style left/right tiled windows differently ("tiled_left", "tiled_right", "tiled_left_and_shaded", "tiled_right_and_shaded"). New Features in Theme Format Version 3.2 ======================================== A new window type 'attached' is added for modal dialogs which are attached to their parent window. (When the attach_modal_dialogs preference is turned on.) If no style is defined for the 'attached' window type, the 'border' window type will be used instead. New Features in Theme Format Version 3.1 ======================================== Additional predefined variables are added for positioning expressions: frame_x_center: the X center of the entire frame, with respect to the piece currently being drawn. frame_y_center: the Y center of the entire frame, with respect to the piece currently being drawn. The element now supports an "ellipsize_width" attribute. When specified, this gives a width at which to ellipsize the title. If not specified, the title will simply be clipped to the title area. New Features in Theme Format Version 3 ====================================== Format version 3 has exactly one new feature; any element in the file can now have a version attribute: version="[<|<=|=>|>] MAJOR.MINOR" (< and > should be to be entity escaped as < and >). If this version check is not met, then the element and its children will be ignored. This allows having alternate sections of the theme file for older and newer version of the Metacity theme format. When placed on the toplevel <metacity_theme> element, an unsatisfied version check will not just cause the contents of the file to be ignored, it will also cause the lookup of a theme file to proceed on and look for an older format 2 or format 1 file. This allows making a metacity-theme-3.xml file that is only used the format version 3.2 or newer is supported, and using metacity-theme-1.xml for older window managers. New Features in Theme Format Version 2 ====================================== The optional attributes rounded_top_left, rounded_top_right, rounded_bottom_left and rounded_bottom_right on <frame_geometry> should now be the radius of the corner in pixels. You may still use the values "false" for 0 and "true" for 5, which means v1 values will still work just fine. <frame_geometry> has a new optional attribute, hide_buttons. If this is true, no buttons will be displayed on the titlebar. Anywhere you can use a positive integer, you can use an integer constant. As well as constant integers and reals, you may define constant colours, thus: <constant name="RevoltingPink" value="#FF00FF"/> <constant name="Background" value="gtk:bg[NORMAL]"/> <frame_style> has two new optional attributes, background and alpha. If you specify alpha, you must specify background. background is a colour used for the background of the frame. alpha is the transparency as a real between 0.0 and 1.0. If the current X server does not support alpha channels, the value is ignored. The filename attribute of <image> may begin with "theme:". If so, the rest of the string is the name of a theme icon. The 64x64 version of the icon is used, except for fallback mini_icons, which use the 16x16 version. This does not affect ordinary resizing. For example: <button function="close" state="normal"> <draw_ops> <include name="active_button"/> <image filename="theme:gnome-logout" x="2" y="2" width="width-4" height="height-4"/> <!-- Note: not "theme:gnome-logout.png" or similar. --> </draw_ops> </button> <menu_icon>s are parsed but ignored. Fallback icons can be specified using <fallback>. There are two optional arguments, icon and mini_icon. The values of these arguments are identical to that of the filename attribute of <image>. Fallback icons are used when a window does not supply its own icon. If a fallback icon is not specified with <fallback>, Metacity will use a built-in icon, as in metacity-theme-1. The <arc> element, as well as the original start_angle and end_angle attributes, may be given from and to attributes. The values of these attributes are given in degrees clockwise, with 0 being straight up. For example: <arc from="0.0" to="90.0" filled="true" color="#FF00FF" x="0" y="5" width="15" height="15"/> <frame state="shaded"> may now take an optional resize attribute, with the same interpretation as the resize attribute on <frame state="normal">. If this attribute is omitted for state="shaded", it defaults to "both". (If it is omitted for state="normal", it remains an error.) In addition to the four <button> functions which are required in metacity-theme-1, there are six new functions in metacity-theme-2: shade, unshade, above, unabove, stick and unstick.

(For purposes of discussion here, I'm excluding things like the panel and the desktop from "windows". It is technically incorrect to do this, but I'm lazy and "windows" is shorter than something like "normal windows". See the end of the discussion for how these special cases are handled.) The basics are easy: Focus method Behavior click When a user clicks on a window, focus it sloppy When an EnterNotify is received, focus the window mouse Same as sloppy, but also defocus when mouse enters DESKTOP window Note that these choices (along with the choice that clicking on a window raises it for the click focus method) introduces the following invariants for focus from mouse activity: Focus method Invariant click The window on top is focused sloppy If the mouse is in a window, then it is focused; if the mouse is not in a window, then the most recently used window is focused. mouse If the mouse is in a non-DESKTOP window, then it is focused; otherwise, the designated "no_focus_window" is focused However, there are a number of cases where the current focus window becomes invalid and another should be chosen. Some examples are when a focused window is closed or minimized, or when the user changes workspaces. In these cases, there needs to be a rule consistent with the above about the new window to choose. Focus method Behavior click Focus the window on top sloppy Focus the window containing the pointer if there is such a window, otherwise focus the most recently used window. mouse Focus the non-DESKTOP window containing the pointer if there is one, otherwise focus the designated "no_focus_window". Note that "most recently used window", as used here, has a slightly different connotation than "most recent to have keyboard focus". This is because when a user activates a window that is a transient, its ancestor(s) should be considered to be more recently used than other windows that have had the keyboard focus more recently. (See bug 157360; this may mean that the alt-tab order should also change simultaneously, although the current implementation does not do that.) Also, sometimes a new window will be mapped (e.g. unminimizing a window or launching a new application). Most users want to interact with new windows right away, so these should typically be focused. This does conflict with the invariants for sloppy and mouse focus modes, so this wouldn't be true for a strict-pointer-focus mode. For all other modes (non-strict-pointer-focus modes), there are only two cases in which a new window shouldn't be focused: 1) If the window takes a while to launch and the user starts interacting with a different application, the new window should not take focus. 2) If the window that will appear was not launched by the user (error dialogs, instant messaging windows, etc.), then the window should not take focus when it appears. To handle these cases, Metacity compares timestamps of the event that caused the launch and the timestamp of the last interaction with the focused window. (Case 2 is handled by the application providing a special timestamp of 0 for the launch time, which ensures that the window that appears doesn't get focus) If the newly launched window isn't focused, some things should be done to alert the user that there is a window to work with: 1) The _NET_WM_DEMANDS_ATTENTION hint should be set 2) If the new window isn't modal for the focused window, it should appear below the focused window so that it doesn't obscure the focused window that the user is interacting with. 3) If the new window is modal to the focused window, the currently focused window should lose focus but the modal window should appear on top. Additionally, the user may decide to use the keyboard instead of the mouse to navigate between windows (referred to as "keynav"). This poses no problems for click-to-focus (because the same invariant can be maintained), but for sloppy and mouse focus it requires extra work to attempt to handle the INHERENTLY CONFLICTING CONSTRAINTS. Metacity does this by having a mouse_mode boolean used to determine which of the two sets of invariants holds. This mode is set according to which method was most recently used to choose a focus window: 1) When receiving EnterNotify events from mouse movement, set mouse_mode to TRUE. 2) When using keynav to choose a focus window (e.g. alt-tab, alt-esc, alt-f2, move-window-to-workspace keybindings), set mouse_mode to FALSE. 3) When handling events that don't choose a focus window but rather need a focus_window chosen for them (e.g. switch-to-workspace keybindings), don't change the mouse_mode and just use the current value. Note that grabs present a special case since they can generate EnterNotify and LeaveNotify events without using the mouse, thus these events should be ignored when the crossing mode is NotifyGrab or NotifyUngrab. THIS MOUSENAV/KEYNAV MODERATION METHOD IS NOT PERFECT--there are corner cases when trying to mix-and-match between mousenav and keynav simultaneously that cause problems; but it appears to be the most reasonable tradeoff and works well in most cases, especially if the user sticks to just mousenav for a long time or just keynav for a long time. Finally, windows of type WM_DOCK or WM_DESKTOP (e.g. the desktop and the panel) present a special case, at least partially due to the lack of decorations. For WM_DESKTOP windows, we only focus them if the user explicitly requests it (e.g. clicks on the window, uses Ctrl-Alt-Tab to navigate to it, uses a keybinding to show the desktop, etc.). For WM_DOCK windows, we do not focus unless we receive a very explicit request (e.g. Ctrl-Alt-Tab or a _NET_ACTIVE_WINDOW message; not normal clicks).

This is what they mean by that: 1) Keynav doesn't maintain the same invariants as mouse navigation for these focus modes; switching back and forth between navigation methods, therefore, may have or appear to have inconsistencies. Examples: a) If the user uses Alt-Tab to change the window with focus, then starts to move the mouse, at that moment the window where the mouse is does not have focus. b) Users expect that a workspace they previously used will not change when the return to it. This means things like window position and stacking order, but also the focus window. Unfortunately, using the original focus window (which would be the most recently used window on that workspace) will sometimes conflict with the invariants for mouse and sloppy focus modes. Users are much more surprised by the invariant being broken than by having the focus window changed (see bug 94545 and probably others), so we maintain the invariant. This only matters when using Ctrl-Alt-Arrow to switch workspaces instead of clicking in the workspace switcher, so this really is a keynav vs mouse issue. Either that, or a windows-are-being-mapped exception. ;-) c) Opening a menu, then moving the mouse to a different window, and then pressing escape to dismiss the menu will result in the window containing the mouse not being focused. This is actually correct behavior (because pressing escape shows that the user is using key navigation to interact with the window containing the menu) but is one of those hard-to-get-right keynav and mouse focus mixture cases. (See bug 101190 for more details) d) Similar to (c), moving the mouse off the menu doesn't immediately focus the window that the mouse goes over, due to an application grab (we couldn't change this and wouldn't want to, but technically it does break the invariant). e) If mouse_mode is off and the user does something to cause focus to change (e.g. switch workspaces, close or minimize a window, etc.) and simultaneously tries to move the mouse, the choice of which window to focus is inherently race-y. (You probably can't satisfy both keynav and mousenav invariants simultaneously...) 2) The sloppy/mouse invariants are often not strictly maintained; for example, we provide an exception to the invariant for newly mapped windows. (Most find that not allowing this exception is confusing) 3) There are an awful lot of little cases to handle to get any focus mode right, even for click-to-focus. Since mouse and sloppy focus have sometimes been hard to even determine what correct behavior is, it is much harder to get them completely right. Plus mouse and sloppy focus users are a minority, decreasing the motivation of window manager implementors to get those focus modes right. 4) Because of -1-, -2-, and -3-, implementations are often buggy or inconsistent and people form their opinions from usage of these implementations. 5) Sloppy focus suffers from a bit of a discoverability problem (for example, I have seen a scientist sit down to a computer for which sloppy focus was in use and take a few minutes before figuring out how window activation worked; granted the layout of the windows in that situation was a bit unusual but it still illustrates that sloppy focus is harder than it should be to figure out). Mouse focus solves this problem; however, people that have experience with other computing environments are accustomed to being able to move their mouse outside the window they are working with and still continue interacting with that window, which conflicts with mouse focus. ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/doc/reference/�������������������������������������������������������������������������0000775�0001750�0001750�00000000000�14211404421�015637� 5����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/doc/reference/Makefile.am��������������������������������������������������������������0000664�0001750�0001750�00000000071�14211404421�017671� 0����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������SUBDIRS = muffin if CLUTTER_DOC SUBDIRS += clutter endif�����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/doc/reference/muffin-docs.sgml���������������������������������������������������������0000664�0001750�0001750�00000003642�14211404421�020742� 0����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������<?xml version="1.0"?> <!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.3//EN" "http://www.oasis-open.org/docbook/xml/4.3/docbookx.dtd" [ <!ENTITY % local.common.attrib "xmlns:xi CDATA #FIXED 'http://www.w3.org/2003/XInclude'"> <!ENTITY version "3.8.2"> ]> <book id="index"> <bookinfo> <title>Muffin Reference Manual This document is for Muffin &version;.

These environment variables are meant as debug tools or overrides for default behaviours: MUFFIN_VERBOSE Enable verbose mode, in which more information is printed to the console. Muffin needs to be built with the --enable-verbose-mode option (enabled by default). For more fine-grained control of the output, see meta_add_verbose_topic(). MUFFIN_DEBUG Traps and prints X errors to the console. MUFFIN_G_FATAL_WARNINGS Causes any logging from the domains Muffin, Gtk, Gdk, Pango or GLib to terminate the process (only when using the log functions in GLib). MUFFIN_USE_LOGFILE Log all messages to a temporary file. MUFFIN_DEBUG_XINERAMA Log extra information about support of the XINERAMA extension. MUFFIN_DEBUG_SM Log extra information about session management. MUFFIN_DEBUG_BUTTON_GRABS Log extra information about button grabs. MUFFIN_SYNC Call XSync after each X call. MUFFIN_DISPLAY Name of the X11 display to use. META_DISABLE_MIPMAPS Disable use of mipmaps for the textures that back window pixmaps. MUFFIN_USE_STATIC_GRAVITY Enable support for clients with static bit-gravity. MUFFIN_WM_CLASS_FILTER Comma-separated list of WM_CLASS names to which to restrict Muffin to. MUFFIN_DISABLE_FALLBACK_COLOR Disable fallback for themed colors, for easier detection of typographical errors.

Compositors that wish to use Mutter must implement a subclass of #MetaPlugin and register it with meta_plugin_manager_set_plugin_type() before calling meta_init() but after g_type_init(). #MetaPlugin provides virtual functions that allow to override default behavior in the window management code, such as the effect to perform when a window is created or when switching workspaces. muffin-5.2.1/doc/reference/muffin-docs.sgml.in0000664000175000017500000000364614211404421021353 0ustar jpeisachjpeisach ]> Muffin Reference Manual This document is for Muffin &version;.

Running Clutter
Environment Variables Clutter automatically checks environment variables during its initialization. These environment variables are meant as debug tools, overrides for default behaviours or to address known hardware issues: CLUTTER_BACKEND Changes the windowing system backend used by Clutter. The allowed values for this environment variable depend on the configuration options used when compiling Clutter. The available values are: x11, for the X11 backend wayland, for the Wayland backend win32, for the Windows backend osx, for the MacOS X backend gdk, for the GDK backend eglnative, for the EGL/KMS backend cex100, for the CEx100 backend All of the above options except for the eglnative and cex100 backends also have an input backend. CLUTTER_INPUT_BACKEND Changes the input backend used by Clutter. The allowed values for this environment variable depend on the configuration options used when compiling Clutter. The available values are: tslib evdev null This environment variable is only useful for setting the input backend when using a windowing system backend that does not have an input API, like the eglnative or the cex100 windowing system backends. CLUTTER_DRIVER Changes the GL driver used when initializing Clutter. The allowed values for this environment variable are: gl3, for the GL driver using a 3.2+ core profile gl, for the GL driver using a legacy profile gles2, for the GLES 2.0 driver any, for the default chosen by Cogl The special '*' value can be used to ask Clutter to use the default list of drivers, e.g. 'CLUTTER_DRIVER=gles2,*' will ask Clutter to try the GLES 2.0 driver first, and then fall back to the default list of Cogl drivers. CLUTTER_SCALE Forces the window scaling factor to that value inside Clutter instead of relying on what backends detect. CLUTTER_TEXT_DIRECTION Forces the text direction of every Pango layout inside Clutter. Valid values are: ltr or rtl CLUTTER_SHOW_FPS Prints out the frames per second achieved by Clutter. CLUTTER_DEFAULT_FPS Sets the default framerate. CLUTTER_DISABLE_MIPMAPPED_TEXT Disables mipmapping when rendering text. CLUTTER_FUZZY_PICK Enables "fuzzy picking". CLUTTER_DEBUG Enables debugging modes for Clutter; debugging modes are used to print debugging messages on the console. Clutter must be compiled with the --enable-debug configuration switch for these messages to be printed out. Multiple debugging modes can be enabled by separating them using a colon (":") or a comma (","). CLUTTER_PAINT Enables paint debugging modes for Clutter; the modes change the way Clutter paints a scene and are useful for debugging the behaviour of the paint cycle. CLUTTER_ENABLE_DIAGNOSTIC When set to 1, enables diagnostic messages for run-time deprecations, similarly to G_ENABLE_DIAGNOSTIC in GLib. On the GLX backend there is also: CLUTTER_VBLANK Selects the sync-to-vblank mode to be used. Valid values are: none, dri or glx
Command Line Arguments Similarly to the environment variables, Clutter also installs command line switches that are parsed during initialization: --clutter-show-fps Equivalent of CLUTTER_SHOW_FPS. Prints the current rendering speed in frames per second. --clutter-default-fps=FPS Equivalent of CLUTTER_DEFAULT_FPS. Sets the default framerate. --clutter-text-direction=DIRECTION Equivalent of CLUTTER_TEXT_DIRECTION. Sets the direction for the text. --clutter-disable-mipmapped-text Equivalent of CLUTTER_DISABLE_MIPMAPPED_TEXT. Disables mipmapping when rendering text. --clutter-use-fuzzy-picking Equivalent of CLUTTER_FUZZY_PICK. Enables "fuzzy" picking. --clutter-debug=FLAGS Equivalent of CLUTTER_DEBUG. Sets FLAGS as the Clutter debugging flags. --clutter-no-debug=FLAGS Unsets FLAGS from the Clutter debugging flags. --cogl-debug=FLAGS Equivalent of COGL_DEBUG. Sets FLAGS as the Cogl debugging flags. --cogl-no-debug=FLAGS Unsets FLAGS from the Cogl debugging flags. --clutter-enable-accessibility Enables accessibility support. The X11 backends also have the following command line options: --display=DISPLAY Sets the X11 display to use. --screen=SCREEN Sets the X11 screen number to use. --synch Make X11 calls synchronous.
The GLX backend also has the following command line option: --vblank=METHOD Equivalent of CLUTTER_VBLANK. Sets the sync-to-vblank method to be used.
Debug flags for Clutter The debugging flags can be used for the CLUTTER_DEBUG environment variable and the --clutter-debug command line switch. Multiple flags can be separated by a colon (:) or a comma (,). actor Generic actor-related notes animation #ClutterAnimation notes backend Backend-related notes, including initialization of the backend features and GL context creation event Event handling notes layout #ClutterLayoutManager notes misc Miscellaneous notes scheduler Notes related to timelines and the master clock script Notes related to #ClutterScript It is possible to get all the debugging notes using the special "all" flag.
Configuration File Clutter will look for files named settings.ini located in the /etc/clutter-1.0 and $XDG_CONFIG_HOME/clutter-1.0 directories. These files must be valid key files (see #GKeyFile in the GLib documentation) and may have three sections: Environment The keys in this section map the environment variables honoured by Clutter. Debug The keys in this section related to the debugging notes that Clutter exposes when compiled with debugging support; similarly to the environment variables and command line arguments related to the debugging notes, Clutter must be compiled with support for these notes in order to use them. Settings The keys in this section strictly map to the #GObject properties exposed by the #ClutterSettings type; if Clutter is running on an X11 platform, the XSettings manager will take precedence over the values specified in the settings.ini file.
Keys available for the Environment group ShowFps A boolean value, equivalent to setting CLUTTER_SHOW_FPS. DisableMipmappedText A boolean value, equivalent to setting CLUTTER_DISABLE_MIPMAPPED_TEXT. UseFuzzyPicking A boolean value, equivalent to setting CLUTTER_FUZZY_PICK. EnableAccessibility A boolean value, equivalent to setting CLUTTER_ENABLE_ACCESSIBILITY. DefaultFps An integer value, equivalent to setting CLUTTER_DEFAULT_FPS. TextDirection A string value, equivalent to setting CLUTTER_TEXT_DIRECTION.
Keys available for the Debug group Debug A string containing the debugging flags, in the same format that should be used with the CLUTTER_DEBUG environment variable. PaintDebug A string containing the paint debugging flags, in the same format that should be used with the CLUTTER_PAINT environment variable. PickDebug A string containing the pick debugging flags, in the same format that should be used with the CLUTTER_PICK environment variable.

Migrating from ClutterAnimation The #ClutterAnimation class, along with the #ClutterActor wrappers clutter_actor_animate(), clutter_actor_animate_with_timeline() and clutter_actor_animate_with_alpha(), has been deprecated in Clutter 1.12, and should not be used in newly written code. The direct replacement for a #ClutterAnimation is the #ClutterPropertyTransition class, which allows the transition of a single #GObject property from an initial value to a final value over a user-defined time using a user-defined easing curve. The #ClutterPropertyTransition class inherits from #ClutterTransition, which allows setting the transition interval, as well as the animatable instance to be transitioned; and from #ClutterTimeline, which allows setting the duration and easing curve of the transition. For instance, the following #ClutterAnimation set up: Can be replaced by #ClutterPropertyTransition: It is important to note that only #ClutterAnimatable implementations can be used directly with #ClutterTransition. A #ClutterPropertyTransition can only animate a single property; if more than one property transition is required, you can use the #ClutterTransitionGroup class to group the transitions together.
Migrating clutter_actor_animate() #ClutterActor animatable properties can use implicit transitions through their setter functions. The duration and easing curve of the animation is controlled by clutter_actor_set_easing_duration() and by clutter_actor_set_easing_mode(), respectively; for instance, the equivalent of the following clutter_actor_animate() call: Can be replaced by the following: The default easing duration for the 1.0 API series is set to 0, which means no transition at all. It is possible to set the easing state of a #ClutterActor to its default values by using clutter_actor_save_easing_state(), and return to the previous values by calling clutter_actor_restore_easing_state() instead. The easing state affects all the animatable properties that are modified after changing it; so, for instance: The animation above will implicitly transition the opacity from its current value to 255 in 500 milliseconds using the default easing curve; at the same time, the size of the actor will be transitioned in 500 milliseconds after a delay of 500 milliseconds to the new size stored in the variables width and height.

Overview Clutter is a GObject based library for creating fast, visually rich, graphical user interfaces. Clutter works by manipulating a scene-graph of 2D surfaces, or 'actors', inside a 3D space. #ClutterActor is the base class for such surfaces. All #ClutterActors can be positioned, scaled and rotated in 3D space. In addition, other properties can be set, such as 2D clipping, children and opacity. Tranforms applied to a parent actor also apply to any children. Actors are also able to receive events. Subclasses of #ClutterActor include #ClutterStage, #ClutterTexture, #ClutterText, #ClutterRectangle, #ClutterCairoTexture, #ClutterGroup and #ClutterBox. #ClutterActors are added to a parent, transformed and then made visible. #ClutterStage is the top level #ClutterActor - it's the representation of a window, or framebuffer. It is created automatically when Clutter is initialised. #ClutterStage is a #ClutterGroup, a class implementing the #ClutterContainer interface. Clutter allows explicit positioning and sizing through the #ClutterFixedLayout layout manager; and implicit positioning and sizing through fluid layout managers like #ClutterBoxLayout, #ClutterFlowLayout and #ClutterTableLayout. Actors inside fixed layout managers like #ClutterGroup and #ClutterStage can also be positioned and sized implicitly using the #ClutterConstraint sub-classes. #ClutterTimelines provide the basis for Clutter's animation utilities. #ClutterActors can be animated using explicit animations through the various #ClutterBehaviour implementations, or implicit animations, through the clutter_actor_animate() function. Animations can also be defined as named states through the #ClutterState class. Clutter further contains a number of utilities, including; #ClutterScript - for loading 'UI definition' files formatted in JSON; #ClutterShader - a class for applying GPU shaders to actors, #ClutterModel - a utility class for MVC list type implementations; #ClutterActions, #ClutterConstraints and #ClutterEffects. muffin-5.2.1/doc/reference/clutter/actor-box.png0000664000175000017500000004277514211404421021744 0ustar jpeisachjpeisachPNG  IHDR8sBIT|d pHYs 7˭tEXtSoftwarewww.inkscape.org< IDATxy\Wa.o3#A$\Hn/R !u[g(T^£8$BxXؖ`Yҙz֙$>=_JR>,,XdZ3Ǚ {4<V?Ao |I{ff ""aBoo8?+3}9~x7JDDo>}w˞VArqw}j~nFT*ϼ y3QG=# /pR|X=2i+_Pو xi@8x1UV+u\Zűc_j!P*~HdDD=@T= I4_ /$\,""^xi9)e"".Rȑ# T&BQLMMe , (E }JCkoaa!Q-,,@k0 cb!".Z\\a; ۶ B!".* m{0 0Qa0l<+(qV "J1Q1R!@Db "cC(DD) "J1Q1R!@Db "cC(DD) "J1Q1R!@Db "cC(DD) "J1Q1R!@Db "cC(DD) "J1Q1R!@Db "!P 3bR9([Q_'3\Hￜ{C.!@DbVߠ. y@x^10Fc !b``lp,`,+1u[ L,TCLϓ .X-XhVDX ̖-zpL@ \7-ó_\N.8x欋;W<hFJWYGhF  [vVpʋE;̕c>nY]񼅪GNd蛰L@J !^ kYY g$-]+P5 Z+@k`HwV`,=mϜ Bo(L|dY7/y86gה.ZD!w$We(N[xl?:kx DOeptƑ7l;x] q*2ݵՏ~(c,'1S2ԙ ^ug8l+ Yk(OҬ pٲj$pו%xoۯ1Umym/0Ivg^!*qo ku,8xꌇgf3׫ ^ǾP82ι񔋽!n^AP*kZ +@㵺LG\-,7`P)5>3\KkD58xE5,CcpfmYJ䂍my~Kh+;E9k+j2h& QFw4n^pv|^C#F2^ l0_Ueg㹸e"'w_Jk'} !a-;} g^uwuR`4Aވ]AV8|2Jh( ܾ&̚k0Įeuh\3c<+qb^G\>9G՗U qfYU#OHܶ' !&Wuh-pˮ*&|e(^5QQ7`4Œ&`#qƲBQ9g'\DJQo$b:>&JGBrdW~}`E15F2 `bAih1m`e0lSsU7 Fcpxl˟JΑF8{<}!@xݮ2#%pzѮR(@uo#YrL(-$F^`[ne}nt)® J *" \1 ӊZlAԧ .Tf\9~r9kjr pDfC3b,\s^hj3trW֖oM| q`$Qm^ֱ0kV_tK^Yl2H4kP]#([}#!98`40܆9r`=8m{ʨFOzX=pT/Fl~/ `AO#gL q/7I\9cP?gQA;^up`jcz2/q6?:tb9@Eˑw%Ʋgl|Yl(/8ؖ[{@]UH{K5 {X "j2AbsB4aXV=7.F*d~yD[R!@Db "cC(]ye"Vqh-T <7\D)eH\1c0(Qtd3g3|)ph\žUYQ7;CN/ZxX䂍θ+* %˙ =Y%6Ȉ( )ۨFZSN"",ނv\l}<np I'1: lr*hN<١ў={.BbwP4{ _8ݡ][0 78nW7^B 0!6QJAk (Zk i(i.ֺQzYnz,˂:]]zN{oy 9Nxn?/2p۫`lr1a<eqض x~q ZB)Ց md20M¼!#a(jz]l/7ګu*DEðurݶ*JE\6e<ضl6R9Bvw=I)av/nhZNT2 q.Z=4Md2d,SGQRj裮;h9\.4!2 jkuZ,~cܣ~D/N @Ra``k}b^|E;v ǎÉ'!.:tߝFQzKe9(WTž={}eZj )V@/i}0 8XBujY4`ddmo(8 X|'֐wy} _>n_|emMI+~n>Ck||333iԿzR###MOc3 >caaa|>1>=d5qz.!`[}گꫯߏ}{}wx_mo{ַkR <v؁뮻8lteJ Pij> 㳟,Ξ=ӧOoo0<<}C];di?CwuWWDc4a? yl6>>>ERwߍACPϽe|ӛބ)<3+mMozwb 'Yo⭷ފw׾_ex~mE!U@kF`4a.\¶alpqסCpM78rN:;cs;6*bR 0lf&q`d2 ϙR ZE:a6vDujf2@thhJIHP} }n޽|=ET--A/n!!,+ 6l6vލ뮻= p@]AJA>dE]ߊ`ٮ: 4azlt"0.gB>Tb:uE[]wJAVr,S˂Y.:m[`Poc$B< /cǎ>9\y啘\\PhqQ?V4 w50{p{3:{ַpA<#عs' R\b\>z3M50{` v"[OE0\q1]:5juj]N[u\Ahi) ُVg}N/Va$$]pK_ԩS'?b3Y.#q׆w v0|AX0 q]?{*+'-%d[F>LV..

Building Clutter
Clutter Dependencies GLib A general-purpose utility library, not specific to graphical user interfaces. GLib provides many useful data types, macros, type conversions, string utilities, file utilities, a main loop abstraction, and so on. GObject The GLib Object System provides the required implementations of a flexible, extensible and intentionally easy to map (into other languages) object-oriented framework for C. Pango Pango is a library for laying out and rendering text, with an emphasis on internationalization. Backend Windowing System Library GLX, EGL (1.1), Cocoa (OS X) and WGL (Windows) Graphics Rendering Open GL (1.3+ or 1.2 with multitexturing support) or Open GL ES (1.1 or 2.0)
Platform-specific instructions
Linux If you are using Debian or Ubuntu, you can install pre-compiled binary packages the normal Debian way following the instructions at http://debian.o-hand.com/. To build Clutter clutter from sources, get the latest source archives from http://www.clutter-project.org/sources/. Once you have extracted the sources from the archive execute the following commands in the top-level directory: $ ./configure $ make # make install You can configure the build with number of additional arguments passed to the configure script, the full list of which can be obtained by running ./configure --help. The following arguments are specific to Clutter: --enable-debug=[no/minimum/yes] Controls the Clutter debugging level. Possible values are: yes (all GLib asserts, checks and runtime debug messages); minimum - just GLib cast checks and runtime debug messages; no (no GLib asserts or checks and no runtime debug messages). The default is yes for development cycles, and minimum for stable releases. You should not use no, unless the only performance critical paths are the GLib type system checks. --enable-cogl-debug=[no/minimum/yes] Controls the COGL debugging level, similarly to --enable-debug. --enable-maintainer-flags=[no/yes] Use strict compiler flags; default=no. --enable-gtk-doc Use gtk-doc to build documentation; default=no. --enable-manual=[no/yes] Build application developers manual; requires jw and xmlto binaries; default=no. --with-flavour=[glx/eglx/eglnative/win32/osx/cex100] Select the Clutter backend; default=glx. --with-imagebackend=[gdk-pixbuf/quartz/internal] Select the image loading backend; default is set to gdk-pixbuf on Linux and Windows, and to quartz on OS X. The internal image loading backend should only be used when porting to a new platform or for testing purposes, and its stability or functionality are not guaranteed. --with-gles=[1.1/2.0] Select the version of GLES to support in COGL; default is 1.1. --with-json=[internal/check] Select whether to use the internal copy of JSON-GLib to parse the ClutterScript UI definition files, or to check for the system installed library; default is internal. --enable-xinput=[no/yes] Whether to enable XInput 1 support; default is no. --enable-introspection=[no/auto/yes] Whether to generate GObject Introspection data at build time; default is auto.
Windows The recommended way of building Clutter for Windows is using the mingw tool chain. This will work either by cross compiling from a Linux installation or directly on Windows using MSYS. See the wiki for more information.
OSX Before you start you should install XCode either from the OSX installation disk or by downloading it from the Apple website. Note: These instructions have only been tested on OS X 10.6 (a.k.a Snow Leopard) Currently the only way to install Clutter for developing applications, or hacking on Clutter itself, is to build it yourself. The recommended route is to install the dependencies with the MacPorts project, by simply invoking: $ sudo port install libpixman-devel cairo-devel pango gtk-doc on a terminal, after installing and updating MacPorts. This should give you all of the required dependencies for building Clutter. It should be noted that building gtk-doc pulls in a lot of other MacPorts dependencies and takes some considerable time. You can omit this dependency so long as you disable documentation when you are configuring the build with --disable-gtk-doc --disable-docs The Clutter Quartz backend is built by passing the --with-flavour=osx command line argument to the configure script. If not passed, the GLX backend will be built. By default, the Quartz backend depends on CoreGraphics in order to load images into textures, but it can also depend on GDK-Pixbuf or an internal, highly experimental PNG and JPEG loader. GTK introspection is untested on OSX (as there isn't a MacPorts package) so it is recommended that you disable this with the --disable-introspection. If building on top of MacPorts, as recommended, the following configure command should suffice: ./configure --with-flavour=osx --disable-introspection --prefix=/opt

Migrating from ClutterBehaviour The #ClutterBehaviour class and its sub-classes have been deprecated since Clutter 1.6. The animation framework provided by #ClutterAnimation, #ClutterAnimator and #ClutterState fully replaces all functionality from the #ClutterBehaviour classes. Generally, animations using #ClutterBehaviour sub-classes can be effectively re-implemented just by using #ClutterActor properties. Here is an example of an animation using a #ClutterBehaviourOpacity instance: ClutterTimeline *timeline = clutter_timeline_new (250); ClutterAlpha *alpha = clutter_alpha_new_full (timeline, CLUTTER_LINEAR); ClutterBehaviour *behaviour = clutter_behaviour_opacity_new (alpha, 255, 0); clutter_behaviour_apply (behaviour, some_actor); clutter_timeline_start (timeline); The same effect can be achieved by using clutter_actor_animate() and the #ClutterActor:opacity property: clutter_actor_set_opacity (some_actor, 255); clutter_actor_animate (some_actor, CLUTTER_LINEAR, 250, "opacity", 0, NULL); #ClutterBehaviours used for continuous animations with looping timelines can still be effectively replaced by looping animations; for instance, the following example of a "pulsating" actor using #ClutterBehaviourScale: static void reverse_timeline (ClutterTimeline *timeline) { ClutterTimelineDirection dir = clutter_timeline_get_direction (timeline); if (dir == CLUTTER_TIMELINE_FORWARD) dir = CLUTTER_TIMELINE_BACKWARD; else dir = CLUTTER_TIMELINE_FORWARD; clutter_timeline_set_direction (timeline, dir); } ClutterTimeline *timeline = clutter_timeline_new (500); ClutterAlpha *alpha = clutter_alpha_new_full (timeline, CLUTTER_LINEAR); ClutterBehaviour *behaviour; g_object_set (some_actor, "scale-gravity", CLUTTER_GRAVITY_CENTER, NULL); behaviour = clutter_behaviour_scale_new (alpha, 1.0, 2.0, 1.0, 2.0); clutter_behaviour_apply (behaviour, some_actor); g_signal_connect (timeline, "completed", G_CALLBACK (reverse_timeline), NULL); clutter_timeline_set_loop (timeline); clutter_timeline_start (timeline); The same effect can be achieved using a #ClutterAnimation: ClutterAnimation *animation = clutter_actor_animate (some_actor, CLUTTER_LINEAR, 500, "scale-x", 2.0, "scale-y", 2.0, "fixed::scale-gravity", CLUTTER_GRAVITY_CENTER, NULL); ClutterTimeline *timeline = clutter_animation_get_timeline (animation); clutter_timeline_set_repeat_count (timeline, -1); clutter_timeline_set_auto_reverse (timeline, TRUE); #ClutterBehaviour sub-classes can be applied to multiple actors, in order to share the duration and the easing mode. It is possible to use the same underlying #ClutterTimeline and #ClutterAlpha instances with #ClutterAnimation to achieve the same effect. Complex animations, spanning multiple actors, should use the #ClutterAnimator and #ClutterState classes instead. muffin-5.2.1/doc/reference/clutter/path-alpha-func.png0000664000175000017500000012024314211404421023001 0ustar jpeisachjpeisachPNG  IHDR"7MsRGBbKGD pHYs 7˭tIME 3 n IDATxY\Wz>scΉL  dXdeI,$Kk}[t?E_{-n˖J,V"by9̻/"D dxW@d;#2ϻ߭xZk(K_?5B!_I)nk@G)~&?_Vx;e3B!BH)ťKkG \)?0ʹ?/ʕ+2B!B>q]-!B!N.ׯ_eu YQ!B' W?Z07샃%!B!Nnܸa @Mk}yssSjۅB!8%|gssefZٔN2B!Bql655vB!Hݦn+O `0`0!BqܕLDQ$##B!)Ea@= ;!B!NrzZτa( SB!8e8& C3ȦKB!BNGY1d(B!8$ !B!]!B!]!B B!B B!Bf=;VJMvs/_ Q=orۇ{G}B!9J) j  =׻pYB!/pp岼vmMWRca86em！eYc$8s1 hd3,/]om[4W!B ]xRH|U?|"*8F$ɽ5e0M56i$ a`tq\읙i1 jBV>S>S0'/j{j(h4}sp5usqŶ-V.4OCӝpt׸(^zgm&_O J|>υ禗5H-M³e[iRL]]+.f ÈϮ\ö.4_gg{s3+jUJ/Ik|;`U_.8w,!5JuǍoޚ|.B! a+/d -F~K L:GWƾx?8b+%"mOgۇmn$)zT{/hf5ۛ4Zn-FRc8% yn~~^sT?

Migrating to ClutterPath Between Clutter 0.8 and Clutter 1.0 the #ClutterBehaviourPath behaviour lost all the path manipulation functions and the ClutterBehaviourBspline class was entirely deprecated. The class that replaced the path description and manipulation functionality is called #ClutterPath. A #ClutterPath allows describing a path using a sequence of #ClutterPathNodes or using a subset of the SVG path description syntax. A Path instance also allows describing complex paths, with linear and Bezier segments and with gaps. Finally, #ClutterPath also provides integration with Cairo, by being able to add paths described by the Cairo cairo_path_t data structure and being able to "replay" a #ClutterPath onto a cairo_t Cairo context.
Creating a #ClutterPath Before Clutter 1.0, all the path-related functions inside #ClutterBehaviourPath and ClutterBehaviourBspline were replicated, but were also subtly different given the different nature of the types of path handled by the two #ClutterBehaviours. ClutterBehaviourPath example The following code shows how a #ClutterBehaviourPath was created prior to the introduction of #ClutterPath. The path described is a square box between 100, 100 and 200, 200. ClutterBehaviour *behaviour; ClutterKnot knots[] = { { 100, 100 }, { 200, 100 }, { 200, 200 }, { 100, 200 }, { 100, 100 } }; behaviour = clutter_behaviour_path_new (alpha, knots, G_N_ELEMENTS (knots)); The construction for a B-Spline path behaviour was similar, though the #ClutterKnots could only describe a curvilinear path. Constructing ClutterPath The following code shows how to construct a #ClutterPath and assign it to a #ClutterBehaviourPath. The created path is the same as the example above. ClutterBehaviour *behaviour; ClutterPath *path; path = clutter_path_new (); clutter_path_add_move_to (path, 100, 100); clutter_path_add_line_to (path, 200, 100); clutter_path_add_line_to (path, 200, 200); clutter_path_add_line_to (path, 100, 200); clutter_path_add_close (path); behaviour = clutter_behaviour_path_new (alpha, path); A #ClutterPath object can be shared across behaviours, just like the #ClutterAlpha objects can. Path can be described by using a subset of the SVG notation for paths as well as using #ClutterPathNode structures. Describing ClutterPath The SVG path notation subset used by #ClutterPath is in string format and can be both set as the whole path description using clutter_path_set_description() or can be added to an existing #ClutterPath using clutter_path_add_string(). The following example shows the same path as the two examples above. ClutterPath *path = clutter_path_new (); clutter_path_set_description (path, "M 100,100 " /* move to */ "L 200,100 " /* line to */ "L 200,200 " "L 100,200 " "z" /* close */); A #ClutterPath can describe not only linear, closed paths; it can also describe paths with Beziér curvers and can add gaps. Describing a mixed ClutterPath A mixed #ClutterPath, with a Beziér curve between the point at 200, 200 and 100, 100 and both control points in 100, 200. ClutterPath *path = clutter_path_new (); clutter_path_set_description (path, "M 100,100 " "L 200,100 " "L 200,200 " "C 100,200 100,200 100,100");
Iterating over a #ClutterPath It is possible to iterate over all the #ClutterPathNodes inside a #ClutterPath by using clutter_path_get_nodes(), which will return a #GSList of #ClutterPathNodes; or by using clutter_path_foreach() with a function. The function pointer passed to clutter_path_foreach() should have the following definition: static void foreach_node (ClutterPathNode *path_node, gpointer user_data) { }
Integration with Cairo A #ClutterPath can use a previously defined cairo_path_t to add new nodes, by using the clutter_path_add_cairo_path() function. It is also possible to paint a #ClutterPath on a Cairo context, by moving the Cairo pen across the nodes of the path using the clutter_path_to_cairo_path() function.

Migrating from ClutterEffect Since version 1.0, Clutter provides the #ClutterAnimation API and the clutter_actor_animate() family of functions as replacements for the ClutterEffectTemplate and clutter_effect_* API for creating simple, one-off animations.
Using <function>clutter_actor_animate()</function> Prior to Clutter 1.0, the way to create simple, one-off animations involving a single actor was the ClutterEffect API. The major downside of this API was that to abstract the duration and easing function of the animation the application developer had to create a ClutterEffectTemplate and keep it around for the duration of the application. The clutter_actor_animate() function performs all of the memory management that was delegated to the ClutterEffectTemplate, freeing the developer from having to deal with object bookkeeping. Another downside of the ClutterEffect API is that every possible animation has its own function (scaling, opacity, rotation, movement, etc.), and new functions cannot be added outside of Clutter. Effect example The following code shows a simple animation using the ClutterEffect API. It animates an actor linearly in 500 milliseconds, by moving it to the (100, 100) coordinates while fading it out. ClutterEffectTemplate *tmpl; tmpl = clutter_effect_template_new_for_duration (500, clutter_ramp_inc_func); clutter_effect_move (tmpl, actor, 100, 100, NULL, NULL); clutter_effect_fade (tmpl, actor, 0, NULL, NULL); g_object_unref (tmpl); The clutter_actor_animate() function will implicitely create a #ClutterAnimation with the passed duration and easing mode, and will bind all the passed properties. All readable and writable properties specified by a #ClutterActor are animatable through clutter_actor_animate(). Animation example The following code shows the clutter_actor_animate() call equivalent to the previous ClutterEffect example. clutter_actor_animate (actor, CLUTTER_LINEAR, 500, "x", 100.0, "y", 100.0, "opacity", 0, NULL); The ClutterEffect API provided a way to be notified of the effect completion. Since the clutter_actor_animate() function creates a #ClutterAnimation instance it's possible to use the #ClutterAnimation::completed signal for the same notification. Effect complete example The following code shows how to receive notification of the completion of the animation. static void on_fade_complete (ClutterActor *actor, gpointer data) { clutter_actor_hide (actor); } ClutterEffectTemplate *tmpl; tmpl = clutter_effect_template_new_for_duration (500, clutter_ramp_inc_func); clutter_effect_fade (tmpl, actor, 0, on_fade_complete, NULL); g_object_unref (tmpl); The clutter_actor_animate() function also has a convenience wrapper that allows to inline the signal connection: Animation completed example The following code shows how to get the same notification as the example above. ClutterAnimation *animation; animation = clutter_actor_animate (actor, CLUTTER_LINEAR, 500, "opacity", 0, NULL); g_signal_connect_swapped (animation, "completed", G_CALLBACK (clutter_actor_hide), actor); /* OR */ clutter_actor_animate (actor, CLUTTER_LINEAR, 500, "opacity", 0, "signal-swapped::completed", clutter_actor_hide, actor, NULL);

Clutter Core Reference Abstract classes and interfaces Base actors Layout managers Actions Constraints Effects Content Paint Objects Clutter Animation Framework Clutter has a fully extensible animation framework providing support for explicit and implicit animations of single actors as well as groups of actors. Base classes Clutter Tools General purpose API User interface definition Generic list model Clutter Backends Clutter is usually compiled against a specific drawing backend. All backends have a common API for querying the underlying platform, and some of them might have specific API exposed by Clutter. Accessibility Clutter provides support for accessibility technologies by implementing the ATK interfaces. Since Clutter is a low-level tool kit, and developers are supposed to create more complex actor classes, we expose a low level API under the Cally namespace; this API can be used as the base to build more accessibility features inside custom derived ClutterActor classes. Base Classes Utility API Migrating from previous version of Clutter This section describes the changes that need to be done in applications using Clutter to use new features or to migrate from old, deprecated API to the new ones.

Every actor has a parent, except the stage, and some actors can be containers. Every actor has a geometry and, when visible, it should paint its contents. The base class for actors is #ClutterActor. allocation The final size of an actor within its parent. For example, an actor might have a preferred minimum size of 20×20 pixels and a natural size of 40×40 pixels, but its parent may decide to allocate 50×20 pixels for it instead. minimum size natural size child A container's child is an actor contained inside it. container An actor which can contain other actors. If a container is meant to be extended using public API it should implement the #ClutterContainer interface; otherwise it is a composite actor. A container can let its children manage their geometry, like #ClutterGroup, or they can take care of assigning one. event Events are the way in which the Clutter backend informs Clutter about external events like pointer motion, button clicks, key presses, etc. geometry An actor's position and size. A geometry can be expressed in actor-relative untransformed coordinates; or in stage-relative, transformed coordinates. minimum size The minimum, useful size of an actor. For instance, a button might have a minimum size of 20×20 millimeters on a touch screen, to retain the ability for the user to press it. A container that manages the size of its children should always try to allocate at least their minimum size. natural size allocation natural size The default size requested by an actor. minimum size allocation parent An actor's parent is the container inside which the actor resides. scenegraph The tree of all actors, starting from the stage at the root and following the containers. stage The top-level container for actors. Depending on the Clutter back end a stage can be associated to a window or to a frame buffer; also depending on the back end is the number of instantiatable stages. Stages in Clutter can be manipulated using the #ClutterStage API. transformation A rotation, scaling or traslation of an actor. Transformations are independent of the actor's geometry. muffin-5.2.1/doc/reference/cogl/0000775000175000017500000000000014211404421016563 5ustar jpeisachjpeisachmuffin-5.2.1/doc/reference/cogl/fill-rule-even-odd.png0000664000175000017500000000606114211404421022666 0ustar jpeisachjpeisachPNG  IHDRhxNsRGB pHYs  tIME .4ІtEXtCommentCreated with GIMPW IDATxۖ8P2`&)_~JDcSJӔd$?!.ӳé  `bRUWsJCt'fjo>?mN4 Ô|mN4 O|YmNh4 O |mNh4  "c*gϿ:4h4/_ cG =ohsGX|@}hP|bI6'X|@}fQ0>;㓿>4wLL}&hZҽ`!X@} q ڜ`!X@} "C@dW߾ >4 3N Ər|W44r7gڜ  hT9  @@c͙6'hh_Dioδ9@@@@x#Z{s Ϧ4d|C]i0˗ı&3"ZO?^#GahspB Eh Z$9_+ C3m I׼n919+VOQ@H(Y=a^̝H}>]WQ'UOQ%j>68{PnΞ\K_/@pk, AFHk2 j `&!56zM;sa/QOK!

Cogl - a modern 3D graphics API
About Cogl Cogl is a modern 3D graphics API with associated utility APIs designed to expose the features of 3D graphics hardware using a more object oriented design than OpenGL. The library has primarily been driven by the practical needs of Clutter but it is not tied to any one toolkit or even constrained to developing UI toolkits.

Cogl Blend Strings Describing GPU blending and texture combining states is rather awkward to do in a consise but also readable fashion. Cogl helps by supporting string based descriptions using a simple syntax.
Some examples Here is an example used for blending: "RGBA = ADD (SRC_COLOR * (SRC_COLOR[A]), DST_COLOR * (1-SRC_COLOR[A]))" In OpenGL terms this replaces glBlendFunc[Separate] and glBlendEquation[Separate] Actually in this case it's more verbose than the GL equivalent: glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); But unless you are familiar with OpenGL or refer to its API documentation you wouldn't know that the default function used by OpenGL is GL_FUNC_ADD nor would you know that the above arguments determine what the source color and destination color will be multiplied by before being adding. Here is an example used for texture combining: "RGB = REPLACE (PREVIOUS)" "A = MODULATE (PREVIOUS, TEXTURE)" In OpenGL terms this replaces glTexEnv, and the above example is equivalent to this OpenGL code: glTexEnvi (GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE); glTexEnvi (GL_TEXTURE_ENV, GL_COMBINE_RGB, GL_REPLACE); glTexEnvi (GL_TEXTURE_ENV, GL_SRC0_RGB, GL_PREVIOUS); glTexEnvi (GL_TEXTURE_ENV, GL_OPERAND0_RGB, GL_SRC_COLOR); glTexEnvi (GL_TEXTURE_ENV, GL_COMBINE_ALPHA, GL_MODULATE); glTexEnvi (GL_TEXTURE_ENV, GL_SRC0_ALPHA, GL_PREVIOUS); glTexEnvi (GL_TEXTURE_ENV, GL_OPERAND0_ALPHA, GL_SRC_COLOR); glTexEnvi (GL_TEXTURE_ENV, GL_SRC1_ALPHA, GL_TEXTURE); glTexEnvi (GL_TEXTURE_ENV, GL_OPERAND1_ALPHA, GL_SRC_COLOR);
Here's the syntax <statement>: <channel-mask>=<function-name>(<arg-list>) You can either use a single statement with an RGBA channel-mask or you can use two statements; one with an A channel-mask and the other with an RGB channel-mask. <channel-mask>: A or RGB or RGBA <function-name>: [A-Za-z_]* <arg-list>: <arg>,<arg> or <arg> or "" I.e. functions may take 0 or more arguments <arg>: <color-source> 1 - <color-source> : Only intended for texture combining <color-source> * ( <factor> ) : Only intended for blending 0 : Only intended for blending See the blending or texture combining sections for further notes and examples. <color-source>: <source-name>[<channel-mask>] <source-name> See the blending or texture combining sections for the list of source-names valid in each context. If a channel mask is not given then the channel mask of the statement is assumed instead. <factor>: 0 1 <color-source> 1-<color-source> SRC_ALPHA_SATURATE

Environment Variables Muffin automatically checks environment variables during its initialization. These environment variables are meant as debug tools or overrides for default behaviours: MUFFIN_VERBOSE Enable verbose mode, in which more information is printed to the console. Muffin needs to be built with the --enable-verbose-mode option (enabled by default). For more fine-grained control of the output, see meta_add_verbose_topic(). MUFFIN_DEBUG Traps and prints X errors to the console. MUFFIN_G_FATAL_WARNINGS Causes any logging from the domains Muffin, Gtk, Gdk, Pango or GLib to terminate the process (only when using the log functions in GLib). MUFFIN_USE_LOGFILE Log all messages to a temporary file. MUFFIN_DEBUG_XINERAMA Log extra information about support of the XINERAMA extension. MUFFIN_DEBUG_SM Log extra information about session management. MUFFIN_DEBUG_BUTTON_GRABS Log extra information about button grabs. MUFFIN_SYNC Call XSync after each X call. MUFFIN_DISPLAY Name of the X11 display to use. META_DISABLE_MIPMAPS Disable use of mipmaps for the textures that back window pixmaps. MUFFIN_USE_STATIC_GRAVITY Enable support for clients with static bit-gravity. MUFFIN_WM_CLASS_FILTER Comma-separated list of WM_CLASS names to which to restrict Muffin to. MUFFIN_DISABLE_FALLBACK_COLOR Disable fallback for themed colors, for easier detection of typographical errors.

Compositors that wish to use Mutter must implement a subclass of #MetaPlugin and register it with meta_plugin_manager_set_plugin_type() before calling meta_init() but after g_type_init(). #MetaPlugin provides virtual functions that allow to override default behavior in the window management code, such as the effect to perform when a window is created or when switching workspaces. muffin-5.2.1/doc/reference/muffin/muffin-overrides.txt0000664000175000017500000000000014211404421023136 0ustar jpeisachjpeisachmuffin-5.2.1/doc/reference/muffin/muffin-docs.sgml.in0000664000175000017500000000364614211404421022637 0ustar jpeisachjpeisach ]> Muffin Reference Manual This document is for Muffin &version;.

Window managers have a few ways in which they are significantly different from other applications. This file, combined with the code overview in doc/code-overview.txt, should hopefully provide a series of relatively quick pointers (hopefully only a few minutes each) to some of the places one can look to orient themselves and get started. Some of this will be general to window managers on X, much will be specific to Metacity, and there's probably some information that's common to programs in general but is nonetheless useful. Overview Administrative issues Minimal Building/Testing Environment Relevant standards and X properties Debugging and testing Debugging logs Adding information to the log Valgrind Testing Utilities Technical gotchas to keep in mind Other important reading Extra reading Ideas for tasks to work on Administrative issues Don't commit substantive code in here without asking hp@redhat.com. Adding translations, no-brainer typo fixes, etc. is fine. The code could use cleanup in a lot of places, feel free to do so. See http://developer.gnome.org/dotplan/for_maintainers.html for information on how to make a release. The only difference from those instructions is that the minor version number of a Metacity release should always be a number from the Fibonacci sequence. Minimal Building/Testing Environment You do not need to _install_ a development version of Metacity to build, run and test it; you can run it from some temporary directory. Also, you do not need to build all of Gnome in order to build a development version of Metacity -- odds are, you may be able to build metacity from CVS without building any other modules. As long as you have gtk+ >= 3.0 and GIO >= 2.25.10 with your distro (gtk+ >= 2.6 if you manually revert the change from bug 348633), you should be able to install your distro's development packagesh (e.g. gtk2-devel, glib-devel, startup-notification-devel on Fedora; also, remember to install the gnome-common package which is needed for building cvs versions of Gnome modules like Metacity) as well as the standard development tools (gcc, autoconf, automake, pkg-config, intltool, and libtool) and be ready to build and test Metacity. Steps to do so: $ svn checkout http://svn.gnome.org/svn/metacity/trunk metacity $ cd metacity $ ./autogen.sh --prefix /usr $ make $ ./src/metacity --replace Again, note that you do not need to run 'make install'. Relevant standards and X properties There are two documents that describe some basics about how window managers should behave: the ICCCM (Inter-Client Communication Conventions Manual) and EWMH (Extended Window Manager Hints). You can find these at the following locations: ICCCM - http://tronche.com/gui/x/icccm/ EWMH - :pserver:anoncvs@pdx.freedesktop.org:/cvs The ICCCM is usually available in RPM or DEB format as well. There is actually an online version of the EWMH, but it is almost always woefully out of date. Just get it from cvs with these commands (the backslash means include the stuff from the next line): cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/icccm-extensions login cvs -d :pserver:anoncvs@cvs.freedesktop.org:/cvs/icccm-extensions \ checkout wm-spec DO NOT GO AND READ THOSE THINGS. THEY ARE REALLY, REALLY BORING. If you do, you'll probably end up catching up on your sleep instead of hacking on Metacity. ;-) Instead, just look at the table of contents and glance at a page or two to get an idea of what's in there. Then only refer to it if you see something weird in the code and you don't know what it is but has some funny looking name like you see in one of those two documents. You can refer to the COMPLIANCE file for additional information on these specifications and Metacity's compliance therewith. One of the major things those documents cover that are useful to learn about immediately are X properties. The right way to learn about those, though, is through hand on experimentation with the xprop command (and then look up things you find from xprop in those two manuals if you're curious enough). First, try running xprop in a terminal and click on one of the windows on your screen. That gives you the x properties for that window. Look through them and get a basic idea of what's there for kicks. Note that you can get rid of some of the verboseness by grepping out the _NET_WM_ICON stuff, i.e. xprop | grep -v _NET_WM_ICON Next, try running xprop -root in a terminal. There's all the properties of the root window (which you can think of as the "main" Xserver window). You can also manually specify individual windows that you want the properties of with xprop -id <id> if you know the id of the window in question. You can get the id of a given window by either running xwininfo, e.g. xwininfo | grep "Window id" | cut -f 4 -d ' ' or by looking at the _NET_CLIENT_STACKING property of the root window. Finally, it can also be useful to add "-spy" (without the quotes) to the xprop command to get it to continually monitor that window and report any changes to you. Debugging information Trying to run a window manager under a typical debugger, such as gdb, unfortunately just doesn't work very well. So, we have to resort to other methods. Debugging logs First, note that you can start a new version of metacity to replace the existing one by running metacity --replace (which also comes in handy in the form "./src/metacity --replace" when trying to quickly test a small change while hacking on metacity without doing a full "make install", though I'm going off topic...) This will allow you to see any warnings printed at the terminal. Sometimes it's useful to have these directed to a logfile instead, which you can do by running METACITY_USE_LOGFILE=1 metacity --replace The logfile it uses will be printed in the terminal. Sometimes, it's useful to get more information than just warnings. You can set METACITY_VERBOSE to do that, like so: METACITY_VERBOSE=1 METACITY_USE_LOGFILE=1 metacity --replace (note that METACITY_VERBOSE=1 can be problematic without METACITY_USE_LOGFILE=1; avoid it unless running in from something that won't be managed by the new Metacity--see bug 305091 for more details). There are also other flags, such as METACITY_DEBUG, most of which I haven't tried and don't know what they do. Go to the source code directory and run grep "METACITY_" * | grep getenv to find out what the other ones are. Adding information to the log Since we can't single step with a debugger, we often have to fall back to the primitive method of getting information we want to know: adding "print" statements. Metacity has a fairly structured way to do this, using the functions meta_warning, meta_topic, and meta_verbose. All three have the same basic format as printf, except that meta_topic also takes a leading enumeration parameter to specify the type of message being shown (makes it easier for grepping in a verbose log). You'll find tons of examples in the source code if you need them; just do a quick grep or look in most any file. Note that meta_topic and meta_verbose messages only appear if verbosity is turned on. I tend to frequently add temporary meta_warning statements (or switch meta_topic or meta_verbose ones to meta_warning ones) and then undo the changes once I've learned the info that I needed. There is also a meta_print_backtrace (which again is only active if verbosity is turned on) that can also be useful if you want to learn how a particular line of code gets called. And, of course, there's always g_assert if you want to make sure some section isn't executed (or isn't executed under certain conditions). Valgrind Valgrind is awesome for finding memory leaks or corruption and uninitialized variables. But I also tend to use it in a non-traditional way as a partial substitute for a normal debugger: it can provide me with a stack trace of where metacity is crashing if I made a change that caused it to do so, which is one of the major uses of debuggers. (And, what makes it cooler than a debugger is that there will also often be warnings pinpointing the cause of the crash from either some kind of simple memory corruption or an uninitialized variable). Sometimes, when I merely want to know what is calling a particular function I'll just throw in an "int i; printf("%d\n", i);" just because valgrind will give me a full stacktrace whenever it sees that uninitialized variable being used (yes, I could use meta_print_backtrace, but that means I have to turn verbosity on). To run metacity under valgrind, use options typical for any Gnome program, such as valgrind --log-file=metacity.log --tool=memcheck --num-callers=48 \ --leak-check=yes --leak-resolution=high --show-reachable=yes \ ./src/metacity --replace where, again, the backslashes mean to join all the stuff on the following line with the previous one. However, there is a downside. Things run a little bit slowly, and it appears that you'll need about 1.5GB of ram, which unfortunately prevents most people from trying this. Testing Utilities src/run-metacity.sh The script src/run-metacity.sh is useful to hack on the window manager. It runs metacity in an Xnest. e.g.: CLIENTS=3 ./run-metacity.sh or DEBUG=memprof ./run-metacity.sh or DEBUG_TEST=1 ./run-metacity-sh or whatever. metacity-message The tool metacity-message can be used as follows: metacity-message reload-theme metacity-message restart metacity-message enable-keybindings metacity-message disable-keybindings The first of these is useful for testing themes, the second is just another way (besides the --restart flag to metacity itself) of restarting metacity, and the third is useful for testing Metacity when running it under an Xnest (typically, the Metacity under the Xnest wouldn't get keybinding notifications--making keyboard navigation not work--but if you disable the keybindings for the global Metacity then the Metacity under the Xnest can then get those keybinding notifications). metacity-window-demo metacity-window-demo is good for trying behavior of various kinds of window without launching a full desktop. Technical gotchas to keep in mind Files that include gdk.h or gtk.h are not supposed to include display.h or window.h or other core files. Files in the core (display.[hc], window.[hc]) are not supposed to include gdk.h or gtk.h. Reasons: "Basically you don't want GDK most of the time. It adds abstractions that cause problems, because they aren't designed to be used in a WM where we do weird stuff (display grabs, and just being the WM). At best GDK adds inefficiency, at worst it breaks things in weird ways where you have to be a GDK guru to figure them out. Owen also told me that they didn't want to start adding a lot of hacks to GDK to let a WM use it; we both agreed back in the mists of time that metacity would only use it for the "UI" bits as it does. Having the split in the source code contains and makes very clear the interface between the WM and GDK/GTK. This keeps people from introducing extra GDK/GTK usage when it isn't needed or appropriate. Also, it speeds up the compilation a bit, though this was perhaps more relevant 5 years ago than it is now. There was also a very old worry that the GDK stuff might have to be in a separate process to work right; that turned out to be untrue. Though who knows what issues the CM will introduce." Remember that strings stored in X properties are not in UTF-8, and they have to end up in UTF-8 before we try putting them through Pango. If you make any X request involving a client window, you have to meta_error_trap_push() around the call; this is not necessary for X requests on the frame windows. Remember that not all windows have frames, and window->frame can be NULL. Other important reading & where to get started Extra reading There are some other important things to read to get oriented as well. These are: http://pobox.com/~hp/features.html rationales.txt doc/code-overview.txt It pays to read http://pobox.com/~hp/features.html in order to understand the philosophy of Metacity. The rationales.txt file has two things: (1) a list of design choices with links in the form of bugzilla bugs that discuss the issue, and (2) a list outstanding bug categories, each of which is tracked by a particular tracker bug in bugzilla from which you can find several closely related bug reports. doc/code-overview.txt provides a fairly good overview of the code, including coverage of the function of the various files, the main structures and their relationships, and places to start looking in the code tailored to general categories of tasks. Ideas for tasks to work on There are a variety of things you could work on in the code. You may have ideas of your own, but in case you don't, let me provide a list of ideas you could choose from: If you're ambitious, there's a list of things Havoc made that he'd really like to see tackled, which you can find at http://log.ometer.com/2004-05.html. Be sure to double check with someone to make sure the item is still relevant if you're interested in one of these. Another place to look for ideas, of course, is bugzilla. One can just do queries and look for things that look fixable. However, perhaps the best way of getting ideas of related tasks to work on, is to look at the second half of the rationales.txt file, which tries to group bugs by type. �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/COPYING��������������������������������������������������������������������������������0000664�0001750�0001750�00000043113�14211404421�014171� 0����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������� GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Suite 500, Boston, MA 02110-1335 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.

properties are looked up in a hash table rather than by iteration over an array. Saves ~44us per window, but also makes the code cleaner. * src/core/display-private.h: * src/core/window-props.c: 2009-01-27 Matthias Claesen <mclasen@redhat.com> * src/core/edge-resistance.c: some lists failed to keep track of their contents and therefore didn't free correctly.

Metacity uses different colormaps for windows with different visuals, so it must specialize the GtkStyle. Closes #568365 and #513944. * src/ui/frames.[ch]: Keep a GtkStyle for each MetaUIFrame, which is obtained by calling gtk_style_attach() on the style for the MetaFrames. When the style of the MetaFrames changes, reattach everything. When we call gtk_style_set_background() pass in the right style. * src/ui/themes.[ch]: Create a _with_style() variant of functions that previously took the style from widget->style passed in, so we can draw with the right style for the colormap. 2009-01-27 Thomas Thurman <tthurman@gnome.org> Added a gconf key to swap the meanings of the right and middle buttons when the modifier key is held down. Closes #437910. Thanks to Matt Kraai for looking over the patch. * src/core/display.c: * src/core/prefs.c: * src/include/prefs.h: * src/metacity.schemas.in.in: 2009-01-27 Thomas Thurman <tthurman@gnome.org> All the window properties are now handled using simple window property handlers. Closes #549886. * src/core/window-private.h: * src/core/window-props.c: * src/core/window.c: 2009-01-26 Thomas Thurman <tthurman@gnome.org> More of the window properties are checked using simple window property handlers. The ones which remain don't actually look up the new value in the ordinary way, and so are a little trickier to merge. Added an "initial" flag to be on the safe side that the behaviour is the same as before (so we don't do things when a window's first mapped that we only used to do when a property changed).

Further efficiencies of scale to come. * src/include/prefs.h: replace META_PREF_*_KEYBINDINGS with META_PREF_KEYBINDINGS * src/core/keybindings.c: replace *_bindings with key_bindings and similar throughout; all window-based functions are now guaranteed to receive a window so don't need to check for themselves (find_handler): moved so it can also be called from rebuild_binding_table * src/core/display-private.h: replace *_bindings with key_bindings * src/core/prefs.c: update_*_binding becomes update_key_binding; (change_notify): tidy up references to "enormous if statement" since it's almost entirely gone now * src/core/all-keybindings.h: new merged version of screen-bindings.h and window-bindings.h. 2008-11-16 David Trowbridge <trowbrds@gmail.com> This change adds support for the new _NET_WM_FULLSCREEN_MONITORS property and client message.

Closes #553980. 2008-10-22 Matthew Martin <mtt.martin@gmail.com> * src/core/window.c (meta_window_set_demands_attention): minimised windows are necessarily obscured. Closes #528927. 2008-10-22 Thomas Thurman <tthurman@gnome.org> Slight transformation of the x-macros used in keybindings to make them clearer: write handler names out in full because the old suffix system was confusing to people skim-reading, and switched the order of the last two parameters so more would generally fit on a screen. * src/core/keybindings.c, src/core/schema-bindings.c src/core/prefs.c: sympathy changes * src/core/window-bindings.h, src/core/screen-bindings.h: transformation as above 2008-10-21 Christian Persch <chpe@gnome.org> * src/Makefile.am: fix build when schemas are not installed.

Closes #557201. 2008-10-18 Thomas Thurman <tthurman@gnome.org> During a discussion with Rodney Dawes about making life easier for the translators, he pointed out that the short and long forms of almost all the keybindings say much the same thing in different words. I believe this is an unconscionable burden to place on translators, and have therefore merged the short and long descriptions into the short description. The long is now a general explanation of the format, plus possibly a notice about reversibility. Closes #469361, and should solve the l10n issue previously mentioned. * src/core/keybindings.c: reflect changes in *-bindings.h * src/core/schema-bindings.c: reflect changes in *-bindings.h * src/core/prefs.c: reflect changes in *-bindings.h * src/core/window-bindings.h: Add flags field, always the same currently, so that it's the same as screen-bindings.h. Also, lose ONLY_BOUND_BY_DEFAULT, since we already had a rather more elegant way to perform the same effect. And merge the long and short descriptions. * src/core/screen-bindings.h (, item): Merge the long and short descriptions. 2008-10-17 Murray Cumming <murrayc@murrayc.com> * configure.in: Call GNOME_DOC_INIT() so we can use the gnome-doc-utils variables in our Makefile.am: * doc/Makefile.am: * doc/creating_themes/Makefile.am * doc/creating_themes/C/creating_metacity_themes.xml: Added this new DocBook document, converted from the HTML here http://blogs.gnome.org/metacity/2008/05/30/themes/ This will be installed for yelp and can be translated and hosted on library.gnome.org. 2008-10-15 Thomas Thurman <tthurman@gnome.org> Since Patrick Niklaus's checkin of 2008-08-14 dealt with windows with no icons not using fallback icons, we don't need fallback icons. * src/ui/theme.h: remove fallback icons from struct. * src/core/iconcache.c (meta_read_icons): don't look for fallbacks. * src/*/ui.[ch] (meta_ui_get_fallback_icons): removed * src/ui/theme-parser.c (typedef, parse_toplevel_element): don't parse fallback specifications. 2008-10-13 Thomas Thurman <tthurman@gnome.org> * po/POTFILES.in: add screen-bindings.h 2008-10-13 Thomas Thurman <tthurman@gnome.org> * po/POTFILES.in: raw schemas is now .in.in * po/LINGUAS: add Latin 2008-10-12 Thomas Thurman <tthurman@gnome.org> Make the bindings in src/core/*-bindings.h generate GConf schemas too. Note that there's an i18n issue (documented in schema-bindings.c) which will be fixed next checkin. * src/core/schema-bindings.c: major fixup to make it ready for use as part of the actual build process. * src/Makefile.am: added magic to make it call schema-bindings after it builds it. * src/core/window-bindings.h: added comments; also, window menu was listed variously as alt-Space and alt-Print; it should have been alt-Space. * src/metacity.schemas.in.in: renamed from s/\.in$//, sentinel added for the generated bindings, warning at the top now untrue, and removed. 2008-10-12 Thomas Thurman <tthurman@gnome.org> Fix annoying bug where alt-tab and friends would jump backwards a space on initial movement. * src/core/screen-bindings.h: although reversed bindings are necessarily reversible, don't set both bits in the constant, or when we test for them we'll get confused. 2008-10-12 Thomas Thurman <tthurman@gnome.org> An attempt to make life a little easier for our beloved translators; this has the same behaviour as before, but removes over thirty translation strings. * src/core/session.c (start_element_handler): all "attribute not found on element" strings are identical * src/ui/theme-parser.c (locate_attributes): allow attribute names to be preceded with "!" (in the code) to show they're required. (parse_aspect_ratio, parse_distance, parse_toplevel_element, parse_style_element, parse_gradient_element, static, parse_border, parse_style_set_element, parse_draw_op_element): use the new "!" prefix for locate_attributes(), or in some cases just the identical constant, for generating this error. * src/ui/theme.c (check_state, meta_theme_validate): add translator comments * src/ui/resizepopup.c (update_size_window): add translator comments 2008-10-06 William Lachance <wrlach@gmail.com> Pass modified mouse button events down to panel windows instead of dealing with them ourselves. Closes #554428. * src/core/display.c (prefs_changed_callback): don't grab mouse buttons on panels * src/core/window.c (meta_window_new_with_attrs): ditto 2008-10-05 Thomas Thurman <tthurman@gnome.org> Second half of the switch to using x-macros for keybindings so that we don't have lots of places with the same information which must stay in the same order. This time it's screen bindings. * src/core/screen-bindings.h: New file, containing screen bindings. * src/core/schema-bindings.c: added ability to output screen bindings. * src/core/window-bindings.h: tiny tweak to comment * src/core/keybindings.c: generate function prototypes using s-b.h; several handlers modified to use ints rather than ints cast into pointers, or renamed. * src/include/prefs.h: generate names of bindings using s-b.h; generate screen_handlers using s-b.h; arguments to bindings are ints and not ints cast to pointers; several handler functions renamed to consistent names. * src/core/prefs.c (meta_prefs_set_num_workspaces, init_bindings): generate screen_handlers using s-b.h; generate screen_string_bindings using s-b.h (and add check for null bindings in init_bindings to enable this simply). 2008-10-05 Thomas Thurman <tthurman@gnome.org> * tools/ppa-magic.py: experimental tool for Launchpad upload 2008-10-05 Thomas Thurman <tthurman@gnome.org> * metacity.doap: Havoc is an author; Thomas has an email address; add a ton of release information going back to the early days, although not right to the beginning. 2008-09-26 Thomas Thurman <tthurman@gnome.org> * autogen.sh: not all versions of /bin/sh can handle this script, so specify one. Also update the error message because we don't use CVS these days. 2008-09-20 Thomas Thurman <tthurman@gnome.org> * po/POTFILES.in: fix name of window-bindings.h 2008-09-20 Thomas Thurman <tthurman@gnome.org> * po/POTFILES.in: added new files and re-sorted 2008-09-12 Vincent Untz <vuntz@gnome.org> Install desktop files in both .../share/applications and .../share/gnome/wm-properties. Copied in from the 2.23.x branch. Closes #549479. * src/metacity-wm.desktop.in: new file * src/.cvsignore: include the above * src/Makefile.am: install the above 2008-09-06 Thomas Thurman <tthurman@gnome.org> An attempt to keep all information about window bindings in the same place. Screen bindings to come. * src/core/window-bindings.h: new file, list of all window bindings * src/include/prefs.h: drop all the existing window-binding macros * src/core/schema-bindings.c (): output all the schema blocks that would appear in metacity.schema for these window bindings. This ought to become part of the build process, and hopefully will soon. When this works it will also close #469361. * src/core/keybindings.c: generate handle_* prototypes using x-macros; populate window_handlers using x-macros; rename several functions to have consistent names; do_handle_move_to_workspace(), handle_move_to_workspace_flip(), and handle_move_to_workspace() all merged into handle_move_to_workspace. * src/core/prefs.c: generate window_bindings and window_string_bindings using x-macros; (meta_prefs_set_compositing_manager) fix unrelated problem with use of GConf functions when GConf was disabled. * src/core/core.c (meta_core_get_menu_accelerator): binding names given as literals since this is the only place in the code they now appear 2008-09-03 Thomas Thurman <tthurman@gnome.org> * src/metacity.desktop.in: removed invalid "Window Manager" group at request of Matthias Clasen. 2008-09-02 Thomas Thurman <tthurman@gnome.org> Desktop file moved, according to policy change.

Believed to fix #468075. 2008-08-16 Ted Percival <ted@midg3t.net> Ensure the user_rect is set sanely for windows that start maximized. Prevents maximized windows from warping across the screen. Fixes bug #504692. * src/core/window.c (save_user_placement): renamed version of meta_window_save_user_rect(). * src/core/window.c (force_save_user_placement): similar, but will always save user_rect even if the window is maximised or fullscreen. * src/core/window.c (meta_window_move_resize_internal): unplaced windows have force_save_user_placement() called instead of save_user_placement(). 2008-08-14 Patrick Niklaus <marex@compiz-fusion.org> Icons for windows are taken from the desktop theme, not from the Metacity theme or from the fallback icon that Metacity provided. Closes #524343. * src/ui/ui.c: Use GtkIconTheme to load the default window icon. Assumes the existence of an icon called "window", otherwise falls back to "gtk-missing-image".

This may fix bug 311868 and others I've heard about (with Valknut, IIRC). It definitely fixes the issues Vytas was seeing with his single instance library. :-) 2006-08-07 Elijah Newren <newren gmail com> * src/constraints.c (setup_constraint_info): patch from Stéphane Rosi to allow moving maximized windows between xineramas again. #323820 2006-08-07 Elijah Newren <newren gmail com> * configure.in: post-release version bump to 2.15.34 2006-08-07 Elijah Newren <newren gmail com> * NEWS: 2.15.21 release 2006-08-07 Elijah Newren <newren gmail com> Add a constrain_titlebar_visible constraint; should fix both bug 333328 and bug 345522.

This is just a summary, to get the full ChangeLog of those changes (approx. 2000 lines): cvs -q -z3 update -Pd -r constraints_experiments cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog Bugs fixed: unfiled - constraints.c is overly complicated[1] unfiled - constraints.c is not robust when all constraints cannot simultaneously be met (constraints need to be prioritized) unfiled - keep-titlebar-onscreen constraint is decoration unaware (since get_outermost_onscreen_positions() forgets to include decorations) unfiled - keyboard snap-moving and snap-resizing snap to hidden edges 86644 - resize should have a shift option like move does 109553 - gravity w/ simultaneous move & resize doesn't work 113601 - maximize vertical and horizontal should toggle and be constrained 122196 - windows show up under vertical panels 122670 - jerky/random resizing of window via keyboard[2] 124582 - keyboard and mouse snap-resizing and snap-moving erroneously moves the window multidimensionally 136307 - don't allow apps to resize themselves off the screen (*cough* filechooser *cough*) 142016, 143784 - windows should not span multiple xineramas unless placed there by the user 143145 - clamp new windows to screensize and force them onscreen, if they'll fit 144126 - Handle pathological strut lists sanely[3] 149867 - fixed aspect ratio windows are difficult to resize[4] 152898 - make screen edges consistent; allow easy slamming of windows into the left, right, and bottom edges of the screen too. 154706 - bouncing weirdness at screen edge with keyboard moving or resizing 156699 - avoid struts when placing windows, if possible (nasty a11y blocker) 302456 - dragging offscreen too restrictive 304857 - wireframe moving off the top of the screen is misleading 308521 - make uni-directional resizing easier with alt-middle-drag and prevent the occasional super annoying resize-the-wrong-side(s) behavior 312007 - snap-resize moves windows with a minimum size constraint 312104 - resizing the top of a window can cause the bottom to grow 319351 - don't instantly snap on mouse-move-snapping, remove braindeadedness of having order of releasing shift and releasing button press matter so much [1] fixed in my opinion, anyway. [2] Actually, it's not totally fixed--it's just annoying instead of almost completely unusable. Matthias had a suggestion that may fix the remainder of the problems (see http://tinyurl.com/bwzuu). [3] This bug was originally about not-quite-so-pathological cases but was left open for the worse cases. The code from the branch handles the remainder of the cases mentioned in this bug. [4] Actually, although it's far better there's still some minor issues left: a slight drift that's only noticeable after lots of resizing, and potential problems with partially onscreen constraints due to not clearing any fixed_directions flags (aspect ratio windows get resized in both directions and thus aren't fixed in one of them) New feature: 81704 - edge resistance for user move and resize operations; in particular 3 different kinds of resistance are implemented: Pixel-Distance: window movement is resisted when it aligns with an edge unless the movement is greater than a threshold number of pixels Timeout: window movement past an edge is prevented until a certain amount of time has elapsed during the operation since the first request to move it past that edge Keyboard-Buildup: when moving or resizing with the keyboard, once a window is aligned with a certain edge it cannot move past until the correct direction has been pressed enough times (e.g. 2 or 3 times) Major changes: - constraints.c has been rewritten; very few lines of code from the old version remain. There is a comment near the top of the function explaining the basics of how the new framework works. A more detailed explanation can be found in doc/how-constraints-works.txt - edge-resistance.[ch] are new files implementing edge-resistance. - boxes.[ch] are new files containing low-level error-prone functions used heavily in constraints.c and edge-resistance.c, among various places throughout the code. testboxes.c contains a thorough testsuite for the boxes.[ch] functions compiled into a program, testboxes. - meta_window_move_resize_internal() *must* be told the gravity of the associated operation (if it's just a move operation, the gravity will be ignored, but for resize and move+resize the correct value is needed) - the craziness of different values that meta_window_move_resize_internal() accepts has been documented in a large comment at the beginning of the function. It may be possible to clean this up some, but until then things will remain as they were before--caller beware. - screen and xinerama usable areas (i.e. places not covered by e.g. panels) are cached in the workspace now, as are the screen and xinerama edges.

We need to add a flag in the theme XML file to say "start me with a transparent background" 2004-08-27 Elijah Newren <newren@math.utah.edu> Prevent an assertion failure that can occur after increasing the number of workspaces; also fix a warning and stacking order when a window is denied focus (fixes #150615) * src/window.c (meta_window_stack_just_below): the position of the window should be set equal to that of the one we want to be below, not 1 lower than that number * src/workspace.c (maybe_add_to_list): new function to add on_all_workspace windows to an mru_list, (meta_workspace_new): call maybe_add_to_list for all windows on the screen in order to initialize the mru_list 2004-08-26 Havoc Pennington <hp@redhat.com> * src/frame.c: delete extra copy of find_argb_visual so things compile * src/compositor.c (HAS_NAME_WINDOW_PIXMAP): copy the XCompositeNameWindowPixmap() stuff from xcompmgr, though I can't say I really know what it's supposed to help with (painting the window border?) 2004-08-26 Havoc Pennington <hp@redhat.com> * src/frame.c, src/theme.c: couple of cosmetic tweaks from resolving my local patch with the bugzilla patch from the 8-19 entry below 2004-08-26 Havoc Pennington <hp@redhat.com> * configure.in: move the have_xrender variable initialization up in the file since it can be set as part of composite check 2004-08-19 Havoc Pennington <hp@redhat.com> Fixes from Rich Wareham * src/display.h (struct _MetaDisplay): add render extension check to the display * src/display.c: check for render * configure.in: don't build compositing manager by default, don't want any nasty surprises; check for render separately from compositing manager * src/frame.c: use an ARGB visual when available for the window frame, so we can be all cool-ass 2004-08-25 Elijah Newren <newren@math.utah.edu> Make dialogs that Metacity shows follow focus-stealing-prevention conventions.

Fri Aug 20 12:54:12 2004 Soeren Sandmann <sandmann@daimi.au.dk> * src/display.c (meta_display_end_grab_op): Move wireframe code before grab is released to prevent endless loops with fullscreen windows. 2004-08-18 Havoc Pennington <hp@redhat.com> * src/display.h (struct _MetaDisplay): track the last_xor_rect separately from the current window size, and then use that to paint the wireframe including the frame, and taking into account shaded windows. * src/window.c (meta_window_get_xor_rect): new function to compute the xor rect; it is not really 100% right, because it uses the frame dimensions from the window at the start of the move/resize. But probably won't break in practice. 2004-08-17 Christian Rose <menthos@menthos.com> * configure.in: Added "bs" to ALL_LINGUAS. 2004-08-16 Kjartan Maraas <kmaraas@gnome.org> * configure.in: Added nb to ALL_LINGUAS. 2004-08-15 Rob Adams <readams@readams.net> * configure.in: Bump version to 2.8.4 2004-08-15 Rob Adams <readams@readams.net> * NEWS: 2.8.3 release 2004-08-15 Rob Adams <readams@readams.net> * src/windows.c (meta_window_update_struts): use height and top/bottom struts to compute gap (copy/paste bug). 2004-08-15 Rob Adams <readams@readams.net> * src/window.c (meta_window_update_struts): Allow struts larger than 1/2 the screen width/height, as long as there's a minimum sized gap between them.

Sun Aug 8 14:20:00 2004 Soeren Sandmann <sandmann@daimi.au.dk> * src/frame.c (meta_frame_set_screen_cursor): Flush after setting cursor. (Rest of #149413). 2004-08-07 Elijah Newren <newren@math.utah.edu> * src/display.c (event_callback): activating the current workspace should be a no-op.

Fix for #149589. 2004-08-07 Elijah Newren <newren@math.utah.edu> * src/window.c, src/window.h: Revert Rob's 2004-07-31 patch that ignored net_wm_user_time when unminimizing a window * src/window.c (meta_window_activate): If a nonzero timestamp is passed, update the window's net_wm_user_time accordingly. (see comments 102-108 of bug 118372) 2004-08-07 Rob Adams <readams@readams.net> Remove some extraneous items that could sometimes appear in the window menu. Fix for #144493. * src/menu.c (menuitems): Change the second separator to key on whether there are any workspaces. (meta_window_menu_new): use NULL label instead of 0 op to identify separator * src/window.c (meta_window_show_menu): Change the conditions on the directions to take into account "holes" in the workspace layout and also only set META_MENU_OP_WORKSPACES when there's more than one workspace. 2004-08-07 Havoc Pennington <hp@redhat.com> * src/screen.c (meta_screen_set_cursor): add XFlush() after setting cursor, #149413 2004-08-06 Elijah Newren <newren@math.utah.edu> * src/display.c (event_callback): Focusing a window upon unshowing the desktop in various ways (panel applet or keybinding) was inconsistent for sloppy and click focus modes. Fix this by calling meta_workspace_focus_default_window after unshowing the desktop via a _NET_SHOWING_DESKTOP message. (resolves #149543) 2004-08-06 Elijah Newren <newren@math.utah.edu> * src/workspace.c (meta_workspace_focus_default_window): prevent keyboard from "getting locked" upon workspace switch, by making sure that the no_focus_window has focus if no other window does. (fixes #147475) 2004-08-05 Elijah Newren <newren@math.utah.edu> Have newly mapped windows that are denied focus appear after the focused window in the alt-tab list. This allows one to switch to such a window with a single alt-tab press. (fixes #149366) * src/window.c (ensure_mru_position_after): new function, (meta_window_show): If newly mapped window is denied focus, call ensure_mru_position_after to make the window appear after the focus window in the mru list. 2004-08-05 Elijah Newren <newren@math.utah.edu> * src/window.c (meta_window_stick): prepend window to mru list instead of appending, since making the window sticky should imply that it is the most recently used, not the least recently. (fixes #149369) 2004-08-04 Elijah Newren <newren@math.utah.edu> * configure.in: post-release version bump (2.8.3) that I forgot to do yesterday. 2004-08-03 Elijah Newren <newren@math.utah.edu> Released 2.8.2 * NEWS, README: update 2004-08-02 Elijah Newren <newren@math.utah.edu> Fix some bugs (reported in #120100) regarding the focus window when using the workspace switcher. * src/display.c (event_callback): When switching workspaces due to a _NET_CURRENT_DESKTOP message, make sure to focus the default window as well. * src/workspace.c (meta_workspace_focus_default_window, meta_workspace_focus_mru_window): Make DOCK or DESKTOP windows have lower priority than others when choosing a window to focus. (For the former function, this means don't focus them at all; for the latter, this means only focus them (via the meta_workspace_focus_top_window call) if no other mru window can be found.) 2004-07-31 Rob Adams <readams@readams.net> Fix bug that caused windows to not be focused on unminimizing because of user time support. * src/window.c (meta_window_new_with_attrs): initialize focus_despite_user_time bit (window_takes_focus_on_map): focus if focus_despite_user_time despite user time, interestingly enough (meta_window_show): reset focus_despite_user_time after showing * src/window.h (_MetaWindow): add focus_despite_user_time bit 2004-07-31 Rob Adams <readams@readams.net> Fix some support for EWMH hints, and fix USER_TIME support to include the DEMANDS_ATTENTION hint. Also includes some code for implementing _NET_RESTACK_WINDOW and _NET_MOVERESIZE_WINDOW, but this is disabled pending feature thaw. * COMPLIANCE: update with new information * src/display.c (meta_display_open): add new hints to list * src/display.h (_MetaDisplay): Add new atoms to struct * src/screen.c (set_supported_hint): update the list of support hints. (set_desktop_viewport_hint): new function sets the viewport hint to (0,0) as required by the spec for WMs with no viewport support. (set_desktop_geometry_hint): new function to set the desktop size hint to the size of the display, since we don't implement large desktop support, as required by the spec. (meta_screen_resize): update the geometry hint on screen resize * src/window.c (meta_window_new_with_attrs): Initialize demands_attention state (set_net_wm_state): Set demands_attention hint in the window state (meta_window_show): If we don't pop up a window because of USER_TIME, set DEMANDS_ATTENTION on the window. (meta_window_focus): When a window receives focus, remove DEMANDS_ATTENTION hint (meta_window_client_message): Allow other apps to set DEMANDS_ATTENTION on a window. Also, if the _NET_ACTIVE_WINDOW hint includes a timestamp, use it. (update_net_wm_state): Read DEMANDS_ATTENTION state also * src/window.h (_MetaWindow): add wm_state_demands_attention bit. 2004-07-22 Rob Adams <readams@readams.net> * src/metacity.schemas.in: Add trailing quotes to keybinding explanation text.

Fixes #144900. 2004-06-24 Elijah Newren <newren@math.utah.edu> Make choice of focus window be consistent for each focus mode. Fixes #135810. * src/delete.c: (meta_window_delete): In some #if 0'ed code, replace meta_workspace_focus_mru_window with meta_workspace_focus_default_window (just in case the code becomes un-#if 0'ed out). * src/screen.c, src/screen.h: Change meta_screen_focus_mouse_window to meta_screen_get_mouse_window, and don't focus the window when found but rather return it. * src/window.c: (meta_window_free, meta_window_minimize): replace meta_workspace_focus_mru_window with meta_workspace_focus_default_window. * src/workspace.c: (meta_workspace_focus_default_window): Focus appropriately for the given focus method: click-to-focus: focus MRU window (== toplevel window) sloppy focus: focus the window under the pointer if there is such a window, otherwise focus the mru window mouse focus: focus the window under the pointer if there is such a window, otherwise don't focus anything 2004-06-24 Elijah Newren <newren@math.utah.edu> * src/window.c: Avoid a race condition on the choice of window to focus after the previously focused window gets closed or minimized. Fixes #131582. 2004-06-24 Elijah Newren <newren@math.utah.edu> * src/metacity.schemas.in: make naming for "move a window"/"move the window"/"move window" more consistent. Patch from Michael Terry for #142235. 2004-06-24 Elijah Newren <newren@math.utah.edu> * src/session.c: Change meta_warning to meta_topic on failure to connect to a session manager. Fixes #136218. 2004-06-17 Elijah Newren <newren@math.utah.edu> Add support for _NET_WM_USER_TIME * src/display.c: (meta_display_open): Add _NET_WM_USER_TIME to atom_names[], (event_callback): Manually set _NET_WM_USER_TIME upon KeyPress (doesn't work since keyboard isn't grabbed) and ButtonPress (does work), this is just a fallback for applications that don't update this themselves. * src/display.h: (struct _MetaDisplay): Add atom_net_wm_user_time field * src/screen.c: (meta_screen_apply_startup_properties): Check for TIMESTAMP provided from startup sequence as well. * src/stack.c: s/meta_window_set_stack_position/meta_window_set_stack_position_no_sync/, (meta_window_set_stack_position): New function which calls the meta_window_set_stack_position_no_sync function followed immediately by calling meta_stack_sync_to_server. * src/window-props.c: (init_net_wm_user_time), (reload_net_wm_user_time): new functions, (reload_wm_hints): also load atom_net_wm_user_time * src/window.c: new XSERVER_TIME_IS_LATER macro (accounts for timestamp wraparound), (meta_window_new_with_attrs): add timestamp attributes, (window_takes_focus_on_map): use TIMESTAMP from startup notification and _NET_WM_USER_TIME to decide whether to focus new windows, (meta_window_show): if app doesn't take focus on map, place it just below the focused window in the stack (process_property_notify): check for changes to _NET_WM_USRE_TIME, (meta_window_stack_just_below): new function * src/window.h: (_MetaWindow struct): new fields for initial_timestamp, initial_timestamp_set, net_wm_user_time_set, and net_wm_user_time, (meta_window_stack_just_below): new function 2004-06-21 Anders Carlsson <andersca@gnome.org> * src/common.h: * src/menu.c: (menu_closed), (activate_cb): * src/window.c: (menu_callback): Add a timestamp argument to menu functions and use it in meta_window_delete. 2004-06-21 Anders Carlsson <andersca@gnome.org> * src/window.c: (meta_window_client_message): Get the timestamp from the client message. Sat Jun 19 02:21:08 2004 Soeren Sandmann <sandmann@daimi.au.dk> Fix bug 143333, support for update counter spec, and 109362, schedule compensation events when events are ignored. * src/display.c (meta_display_open): Add _NET_WM_SYNC_REQUEST and _NET_WM_SYNC_REQUEST_COUNTER atoms. Remove the old METACITY_SYNC_COUNTER stuff. (meta_display_begin_op): Setup the sync counter * src/xprops.c, src/xprops.h, src/window-props.c, src/display.h: Add new atoms. * src/window.c (send_sync_request): new function. (meta_window_move_resize_internal): send a sync request before resizing. (check_move_resize_frequence): Rework logic to also check the SYNC case. If an event is ignored return the remaining time.

The previous default was almost violent in its lack of appreciation for human beings. In fact, this entire setting should probably be removed, but for now, let's just fix the default. Permission granted by Havoc. 2004-05-04 Elijah Newren <newren@math.utah.edu> * configure.in: 2.8.1 * NEWS: update 2004-05-02 Rob Adams <readams@readams.net> * src/metacity-dialog.c (warn_about_no_sm_support): make the no sm support warning dialog resizable, since the default GTK warning dialog not has default not resizable.

Patch from Neil Muller <neil@dip.sun.ac.za> in bug #133979. * src/iconcache.c: (find_largest_sizes), (find_best_size): Don't down-size nitems from a gulong to an int. Fixes a crash with enlightenment, apparently. 2004-04-16 Iñaki Larrañaga <dooteo@euskalgnu.org> * configure.in: Added "eu" (Basque) to ALL_LINGUAS. 2004-04-15 Elijah Newren <newren@math.utah.edu> * src/display.c: Prevent unwanted grab op from occurring. Previously, for some people under certain conditions, clicking and releasing the mouse button rapidly enough would result in Metacity starting a move operation due to ignoring the button release. This should fix that problem (it does for me). See bug 136587. 2004-04-11 Rob Adams <readams@readams.net> * configure.in: Make the --enable-xinerama switch work properly. Fix for #138562 from foser@gentoo.org. 2004-04-09 Guntupalli Karunakar <karunakar@freedomink.org> * configure.in: Added "gu" (Gujarati) to ALL_LINGUAS. 2004-03-27 Tõivo Leedjärv <toivo@linux.ee> * configure.in: Added et to ALL_LINGUAS. 2004-03-24 Guntupalli Karunakar <karunakar@freedomink.org> * configure.in: Added "pa" (Punjabi) to ALL_LINGUAS. 2004-03-21 Havoc Pennington <hp@redhat.com> * configure.in: 2.8.0 * NEWS: update 2004-03-07 Elijah Newren <newren@math.utah.edu> * rationales.txt: Bring up to date (see bug 136252). 2004-03-07 Havoc Pennington <hp@redhat.com> * configure.in: 2.7.1 2004-03-04 Paisa Seeluangsawat <paisa@users.sf.net> * configure.in: Added "th" (Thai) to ALL_LINGUAS. 2004-03-01 Rob Adams <readams@readams.net> * src/stack.c (compute_layer): don't promote due to transiency; we handle that elsewhere now. (ensure_above): perform layer promotion here as well as stack position promotion. Note that this means that we need to do stack constraints now on layer change now. (get_maximum_layer_of_ancestor): remove function (max_layer_func): remove function (MaxLayerData): remove struct 2004-02-28 Rob Adams <readams@readams.net> Revert 2/27 patch for layer promotion. 2004-02-27 Rob Adams <readams@readams.net> * src/window.c (meta_window_notify_focus): only move on MRU list if the window belongs on the workspace, since the FocusIn event could be for a window whose workspace we've since switched away from. Possible fix for #122016. * src/workspace.c (meta_workspace_contains_window): search for the workspace in window->workspaces rather than the window in workspace->windows. Since the number of workspaces is at most 36, this is a O(1) lookup rather than a O(n) lookup. Sorry; couldn't resist. 2004-02-27 Rob Adams <readams@readams.net> * src/metacity.schemas.in: Change move_to_workspace_left/right/up/down keybindings to <Control><Alt><Shift> arrow to avoid conflicting with new keybindings in spacial nautilus. 2004-02-27 Rob Adams <readams@readams.net> Handle layer promotion of transient descendants of layer-promoted windows to also be layer promoted, using a simple iterative algorithm. * src/stack.c (compute_layer): change name to promote_layer, and convert to simply perform any necessary layer promotion without computing the standalone layer. (max_layer_func): use window->layer instead of get_standalone_layer (get_maximum_layer_of_ancestor): use window->layer instead of get_standalone_layer (meta_stack_ensure_sorted): implement iterative algorithm, explained in a long comment. * src/window.h: add a tmp_layer field used by stack.c for determining if the stack is dirty or not, since maintaining this information in meta_stack_ensure_sorted is no longer practical. 2004-02-23 Rob Adams <readams@readams.net> Add my copyright notice to a number of files on which it should already exist. * src/window.c (meta_window_notify_focus): modify code to move to front of MRU list so that we can have an assert that it was there in the first place. This code may be causing some crashes. See #131196. 2004-02-22 Christian Rose <menthos@menthos.com> * configure.in: Added "en_CA" to ALL_LINGUAS. 2004-02-19 Rob Adams <readams@readams.net> * src/prefs.h: remove trailing comma in MetaKeyBindingAction enum. Fix for #134868 thanks to bugzilla-gnome@thewrittenword.com. 2004-02-16 Rob Adams <readams@readams.net> * src/window.c (update_move): reset drag state after shaking loose or reattaching. Fix for #132625. 2004-02-15 Anders Carlsson <andersca@gnome.org> * src/menu.c (meta_window_menu_new): Actually translate a message, don't just mark it for translation. 2004-02-14 Elijah Newren <newren@math.utah.edu> * src/workspace.c: When moving a window to a different workspace, prepend it to the mru list insted of appending it. Fixes #134368. 2004-02-14 Rob Adams <readams@readams.net> If we're moving a window and receive a _NET_CURRENT_DESKTOP message indicating a workspace switch, bring along the drag window to the new workspace, solving a potentially weird bug where the window would be lost on the old workspace. This also makes it possible to implement edge flipping in an external program with just a few lines of code. Patch for #131630 from ed@catmur.co.uk. * src/keybindings.c (switch_to_workspace): remove function -- no longer needed. (handle_activate_workspace): call meta_workspace_activate instead of switch_to_workspace * src/workspace.c (meta_workspace_activate_with_focus): if we're in a move grab op, bring along the drag window. 2004-02-14 Rob Adams <readams@readams.net> * configure.in: Add configure option to not even try using xinerama, to make metacity buildable on systems with no shared library version of the xinerama libraries. Patch for #134203 from Julio M. Merino Vidal. 2004-02-01 Rob Adams <readams@readams.net> * COMPLIANCE: Bring up to date with current draft EWHM. 2004-01-27 James M. Cape <jcape@ignore-your.tv> * src/themes/Esco/metacity-theme-1.xml: Use the 'utility' frame for dialogs too. 2004-01-24 James M. Cape <jcape@ignore-your.tv> * src/themes/Esco/metacity-theme-1.xml: Updated this theme. 2004-01-21 Elijah Newren <newren@math.utah.edu> * src/screen.c (set_supported_hint): Removed some duplicate entries. 2004-01-17 Rob Adams <readams@readams.net> * src/metacity.schemas.in: Default binding removed for toggle_shaded, since we don't have anything in the graphical UI for it any more. 2004-01-17 Rob Adams <readams@readams.net> * src/window.c (meta_window_show_menu): Don't show left/right/up/down if a window is sticky. Make "On Top" insensitive for docks, splash screens, and desktops since it has no effect anyway. 2004-01-10 Rob Adams <readams@readams.net> * src/metacity.schemas.in: update default action_double_click_titlebar to be toggle_maximize instead of toggle_shade. See #131126. 2004-01-10 Rob Adams <readams@readams.net> * src/constraints.c (meta_window_constrain): if we maximize after placement, and the window is too big to fix in the work area, define a sane saved_rect approximately with dimensions three-quarters approximately three quarters the size of the work area. This avoids the problem where large windows would unmaximize and actually get bigger. See #93590. 2004-01-09 Thomas Fitzsimmons <fitzsim@redhat.com> Add _NET_FRAME_EXTENTS and _NET_REQUEST_FRAME_EXTENTS. * src/display.c: include xprops.h (process_request_frame_extents): new function (meta_display_open): add _NET_FRAME_EXTENTS and _NET_REQUEST_FRAME_EXTENTS atoms (event_callback): handle frame extents message * src/display.h (struct _MetaDisplay): add atom_net_frame_extents and atom_net_request_frame_extents * src/theme.c (meta_pango_font_desc_get_text_height): make font_desc parameter const * src/ui.c: include prefs.h (meta_ui_theme_get_frame_borders): new function * src/window.c (update_net_frame_extents): new function (meta_window_move_resize_internal): update frame extents property when frame geometry changes * src/screen.c (set_supported_hint): add atom_net_frame_extents and atom_net_request_frame_extents 2004-01-09 Calum Benson <calum.benson@sun.com> * src/themes/Atlanta/metacity-theme-1.xml: Ensure Atlanta window buttons get larger when using large print themes. Fixes #123469. 2003-01-04 Rob Adams <readams@readams.net> Maintain the button grab for sloppy and mouse focus all the time. This fixes a number of problem introduced by trying to drop the grab; we now do this only for click to focus mode. This has the unfortunate effect that #102209 reappears for sloppy and mouse focus, but this seems unavoidable, because of limitations in the X protocol. See #115072. * src/display.c (meta_display_grab_focus_window_button): #if 0 the section on not grabbing unless in click-to-focus mode. * src/window.c (meta_window_notify_focus): drop focus button grab on FocusIn and acquire it on FocusOut only when in click-to-focus mode. 2004-01-03 Robert Sedak <robert.sedak@sk.htnet.hr> * configure.in: Added "hr" in ALL_LINGUAS. 2003-01-02 Rob Adams <readams@readams.net> * README: Update reference to EWMH. * HACKING: Add a reference to COMPLIANCE and to the ICCCM and EWHM. 2003-12-25 Havoc Pennington <hp@redhat.com> * src/compositor.c (process_reparent): handle ReparentNotify, and add a lot of debug output. 2003-12-25 Havoc Pennington <hp@redhat.com> * src/compositor.c (meta_compositor_process_event): change to track all children of the root window, not only mapped children; this keeps us from losing track of the stacking order * src/display.c (event_callback): don't do any of the compositor event handling inline, do it all in compositor.c 2003-12-21 Rob Adams <readams@readams.net * src/main.c (main): fix minor punctuation error in a string. Fix for #129805. 2003-12-20 Rob Adams <readams@readams.net> Reorganize the window menu according to discussion on #110904. The workspace name mnemonic chunk of the patch is thanks to Jonathan Blandford. * src/common.h: add MENU_OP_ABOVE, MENU_OP_UNABOVE, MENU_UP_MOVE_TO_* menu ops. * src/core.c (meta_core_get_menu_accelerator): add accelerator for the new menu ops. * src/menu.c: add checked attribute in _MenuItem struct to display a checkmark next to a menu item. Add the new menu items to menuitems. (get_workspace_name_with_accel): Add mnemonics even to renamed workspaces. (menu_item_new): provide support for the checked attribute (meta_window_menu_new): construct new submenu for workspace switching. * src/window.c (menu_callback): implement support for the new menu ops. (meta_window_show_menu): don't use the OP_*SHAPE operations, and compute which of the OP_MOVE_TO_* ops should be used for the current workspace and workspace layout. Add the OP_*ABOVE operations. 2003-12-20 Arafat Medini <lumina@silverpen.de> * configure.in: Added Arabic locale "ar" to ALL_LINGUAS 2003-12-17 Rob Adams <readams@readams.net> * src/display.c (meta_display_open): initialize grab_wireframe_active to FALSE. Fix for #128090. 2003-12-17 Rob Adams <readams@readams.net> * src/tabpopup.c (meta_ui_tab_popup_new): Don't try to call utf8_strndup on a null title for an entry. Fix for #128566. * src/workspace.c (meta_workspace_free): Call g_list_free on the mru_list, since with sticky windows that MRU list could well not be emtpy. See #122016. 2003-12-13 Rob Adams <readams@readams.net> * src/window.c (meta_window_new_with_attrs): set on_all_workspaces in all cases _before_ adding to the workspaces, so that windows initially on all workspaces are added correctly to the MRU lists. Fix for #120907. * src/workspace.c (meta_workspace_add_window): handle sticky windows so that we add to add mru lists if needed (meta_workspace_remove_window): handle sticky windows so that they are removed from all mru lists if needed. 2003-12-12 Havoc Pennington <hp@redhat.com> * src/window.c (meta_window_free): unstick window to get it out of mru_list it should not be in; assert that window has been removed from all mru_list. Perhaps fixes #122016 crash. 2003-11-29 Havoc Pennington <hp@redhat.com> * fix up compositing manager to somewhat work 2003-11-26 Rob Adams <readams@readams.net> * COMPLIANCE: fix a couple of minor typos. 2003-11-24 Havoc Pennington <hp@redhat.com> * src/compositor.c (meta_compositor_new): fix the extension checks 2003-11-24 Havoc Pennington <hp@redhat.com> * src/iconcache.c (meta_icon_cache_init): init prev_mask field * src/window.c (meta_window_new_with_attrs): init xgroup_leader prior to use 2003-11-24 Havoc Pennington <hp@redhat.com> * src/display.c (meta_display_begin_grab_op): add an event_serial argument and use it when the pointer is already grabbed automatically on the button press. May fix bug #126871 2003-11-24 Havoc Pennington <hp@redhat.com> * Apply patch from Gregory Merchan to avoid using CurrentTime when setting input focus. Bug #108881 2003-11-23 Havoc Pennington <hp@redhat.com> * src/compositor.c: move xcompmgr code in here (minus drop shadows), untested since Keith's server just crashes at the moment. "It compiles" 2003-11-20 Havoc Pennington <hp@redhat.com> * src/window.c (meta_window_new_with_attrs): new function * src/display.c, src/screen.c: create the compositor and feed windows and events to it 2003-11-20 Havoc Pennington <hp@redhat.com> * src/window.c (meta_window_notify_focus): revert the change here 2003-11-17 Rob Adams <readams@readams.net * src/window.c (set_allowed_actions_hint): increment i between resize and fullscreen. 2003-11-16 Rob Adams <readams@readams.net> Create COMPLIANCE document describing metacity specification compliance. Right now gives detailed EWMH compliance; still need to add ICCCM compliance information. Also some minor fixes to bring metacity into compliance on some points. * COMPLIANCE: new file * src/display.h, src/display.c (meta_display_open), src/screen.c (set_supported_hint): add atom_net_wm_action_fullscreen and atom_net_wm_action_minimize * src/window.c (set_allowed_actions_hint): some fixes to which hints to set and add fullscreen and minimize. 2003-11-16 Rob Adams <readams@readams.net> * src/window.c (meta_window_notify_focus): add paranoia check to make sure a window is really on a workspace before inserting it at the beginning of the MRU list. Maybe there's a race condition with focusing and workspace switching. Hopefully a fix for #122016. 2003-11-15 Havoc Pennington <hp@redhat.com> * src/main.c (main): fix warning * src/compositor.c: add a new file to contain compositing manager functionality; not yet implemented at all. 2003-11-15 Rob Adams <readams@readams.net> Inherit visual from frame window so that metacity will work with the new compositing manager extension work by Keith on freedesktop.org, so that ARGB windows can be full alpha-transparent without a metacity frame getting drawn in the background. In the long term, we need to actually set alpha values when drawing the frame so that it will really work; this is a stopgap solution. Patch from Keith Packard; see Bug 126875. * src/frame.c (meta_window_ensure_frame): pass client visual to frame. * src/ui.[ch] (meta_ui_create_frame_window): add new xvisual parameter and use it to create new window. 2003-11-15 Rob Adams <readams@readams.net> * src/window.c (update_net_wm_type): don't set window->type_atom here so that the type-inference code will actually be called. Fix for #126873 from Keith Packard. 2003-11-08 Rob Adams <readams@readams.net> * src/window.c (meta_window_move_resize_internal): configure frame first if we grow more than we shrink combined in both dimensions. Patch from Soren Sandmann for #108925. 2003-11-07 Rob Adams <readams@readams.net> * src/place.c (meta_window_place): use maximize_after_placement to automaximize in meta_window_place; avoids a problem with not recalculating the frame geometry after auto-maximizing. 2003-11-07 Rob Adams <readams@readams.net> * src/window.c (window_should_be_showing): show the window if it's a transient of a dock or desktop, since otherwise such windows are invisible in show desktop mode. Fix for #124648. 2003-11-07 Rob Adams <readams@readams.net> * src/main.c (main): Try harder to find a theme in the event that the theme in the preference cannot be found. Patch from Marcin Krzyzanowski. See #125815. * src/place.c (meta_window_place): use "visual" centering for dialog placement and clip new dialogs to an xinerama workspace. Fix for #118336. 2003-10-30 Havoc Pennington <hp@redhat.com> * src/menu.c (meta_window_menu_new): patch to avoid creating stick/unstick menu items when only one workspace, bug #116563 from Michael Terry 2003-10-25 Havoc Pennington <hp@redhat.com> * src/window.c (meta_window_notify_focus): if a window is focused which is not either a dock or a transient in the same group as a dock, shuffle all dock/desktop windows to the end of the MRU list so they won't annoyingly get focus all the time. #123816 2003-10-15 Yukihiro Nakai <nakai@gnome.gr.jp> Gettextize metacity-theme-viewer. #121747 * src/theme-viewer.c: gettextize. * po/POTFILES.in: Add src/theme-viewer.c 2003-10-13 Havoc Pennington <hp@redhat.com> In the "prefs cause code complexity" department, here's a "sloppy focus die die die" kind of moment. * src/display.c (meta_display_grab_focus_window_button): don't grab in sloppy focus mode, since we were dropping the grab on window enter anyway this just removes races from the current behavior. * src/display.c (prefs_changed_callback): ungrab/grab on focus mode changes, since we treat sloppy and click differently. 2003-10-12 Havoc Pennington <hp@redhat.com> Merge reduced_resources mode patch from the branch. Offers wireframe and no-animations. * src/window.c (implement_showing): no animation if we are in reduced resources mode * src/prefs.c: add REDUCED_RESOURCES pref * src/window.c (meta_window_update_keyboard_resize): fix to modify grab_anchor_window_pos to grab_wireframe_rect if appropriate instead of window->rect * src/display.h (struct _MetaDisplay): add grab_start_serial used to avoid responding to events that occurred prior to the grab initialization. Still broken in various ways, specifically EnterNotify that occurred prior to XGrabPointer is processed as if it occurred after. * src/window.c (meta_window_update_keyboard_move): add this instead of meta_window_warp_pointer() crack * src/effects.c (meta_effects_update_wireframe): draw a kind of grid for the wireframe, instead of just a rectangle, like twm * src/screen.c (meta_screen_new): line width of 3 for the XOR gc "Reduced resources" mode based on wireframe patch from Erwann Chenede. Still pretty buggy. * src/keybindings.c (process_keyboard_move_grab) (process_keyboard_resize_grab): add gruesome wireframe hacks * src/display.c (meta_display_end_grab_op): end wireframe (meta_display_begin_grab_op): begin wireframe * src/effects.c (meta_effects_end_wireframe) (meta_effects_update_wireframe, meta_effects_begin_wireframe): routines to draw the wireframe stuff * src/window.c (window_should_be_showing): hide window when doing wireframe, commented out as it breaks grab * src/window.c (meta_window_refresh_resize_popup): handle wireframe * src/screen.c (meta_screen_new): create a screen->root_xor_gc for use in drawing wireframes * src/frames.c (meta_frames_push_delay_exposes): repaint everything before we delay 2003-10-11 Havoc Pennington <hp@pobox.com> * src/display.c (meta_display_begin_grab_op): initialize display->grab_have_pointer to FALSE, previously I think you could get a case where we didn't have the grab and thought we did. Bugs were reported with this happening. Of course we still have the "why did the grab fail" problem, but it should be less noticeable with this fixed. 2003-10-06 Rob Adams <readams@readams.net> * src/constraints.c (constraint_onscreen_*_func): disable onscreen resize constraints for right, left, and bottom, since there is no way to violate onscreen constraints by resizing in these directions and the code to implement the constraints made some incorrect assumptions. Fix for #120701, #120756, #123165, #123631, #123838. 2003-10-06 Žygimantas Beručka <uid0@tuxfamily.org> * configure.in: Added "lt" to ALL_LINGUAS 2003-10-01 Havoc Pennington <hp@redhat.com> * NEWS: update * configure.in: 2.6.2 2003-09-30 Havoc Pennington <hp@redhat.com> * src/window.c (meta_window_queue_move_resize): add the moveresize idle at META_PRIORITY_RESIZE so it runs before GTK does any drawing, may fix bug #109211 (seems to for me) * src/ui.h (META_PRIORITY_RESIZE): add this between GTK resize/redraw priorities * src/display.c (meta_display_queue_retheme_all_windows): remove some debug spew from meta_warning 2003-09-30 Havoc Pennington <hp@redhat.com> * src/testasyncgetprop.c: remove nonstandard header include, #121870 2003-09-30 Havoc Pennington <hp@redhat.com> * src/tools/metacity-message.c (main): call bind_textdomain_codeset(), fix from Yukihiro Nakai bug #121743 2003-07-28 Rached Ben Mustapha <rached@benmur.net> Fix bug #118428 * src/window.c (redraw_icon): Also redraw window icon if the window is not mapped but its frame is.

See #116285. 2003-06-26 Havoc Pennington <hp@pobox.com> * src/workspace.c (meta_workspace_invalidate_work_area): nuke the lists of struts here, to improve confidence that we never try to use them after a window with rects in the list gets freed. (it wasn't broken before I don't think, just making the code more robust against future mods) * src/window.c (meta_window_update_struts): replace magic "75" with a macro * src/constraints.c (constraint_hints_applies_func): don't apply hints to maximized or fullscreen, rather than only fullscreen (constrain_move): add paranoia max number of iterations to the heuristic loop 2003-06-26 Rob Adams <robadams@ucla.edu> Add keybinding to allow the user to toggle _NET_WM_STATE_ABOVE on windows.

Unleash the per-xinerama work areas. * src/constraints.c (get_outermost_onscreen_positions): Use the current window position along with the new per-workspace strut rects to compute the constraints that apply to a particular window. (constraint_hint_applies_func): don't do hints constraints on fullscreen windows (update_position_limits): for maximized windows use the work areas to set the position limits; for other windows rely on the struts constraints to be computed later in get_outermost_onscreen_positions (meta_window_constrain): don't apply aspect ratio hints to full screen windows * src/display.c (meta_display_open): add _NET_WM_STRUT_PARTIAL atom (meta_rectangle_equal): new helper function for MetaRectangles (event_queue_callback): #ifndef out if USE_GDK_DISPLAY not set to avoid compiler warning * src/display.h: add atom_net_wm_strut_partial, and add meta_rectangle_equal. * src/screen.c (meta_screen_rect_intersects_xinerama): change _window_intersects_ to _rect_intersects_ which is more useful now.

Fix for #106123 from Julio Merino 2003-06-12 Rob Adams <robadams@ucla.edu> Remove legacy support for Gnome 1 hints, since we deem it unlikely that anyone is running a current metacity with Gnome 1. The removed hints are _WIN_WORKSPACE, _WIN_LAYER, _WIN_PROTOCOLS, _WIN_SUPPORTING_WM_CHECK, and _WIN_HINTS. Thanks to Ben Jansens for much of this patch. * display.c (meta_display_open): remove hints * display.h: remove atoms for hints * screen.c (set_wm_check_hint): don't set legacy hint (set_supported_hint): don't set legacy hint * window-props.c (init_win_workspace): removed (reload_win_workspace): removed (meta_display_init_window_prop_hooks): remove hints * window.h: remove do_not_cover flag * window.c: remove GnomeWinHints enum (recalc_do_not_cover_struts): removed (meta_window_new): don't initialize removed flags or compute legacy struts (move_resize_cmp): removed (idle_move_resize): Don't bother sorting the idle queue (meta_window_client_message): don't set legacy hint (process_property_notify): remove hints (update_net_wm_type): don't fall back to WIN_LAYER hint (update_struts): remove legacy struts 2003-06-12 Havoc Pennington <hp@pobox.com> * src/display.c (event_callback): make raise-on-click explicitly only happen in click to focus mode. * src/window.c (update_move): apply patch from Jurg Billeter to allow you to "shake loose" maximized windows and move them between Xinerama heads. #93586 * src/display.c: delete event_queue_callback * src/display.h (struct _MetaDisplay): get rid of grab_current_window_pos and grab_current_root_[xy] as I could find absolutely no code using them for anything. They were just sort of randomly assigned to for no apparent reason. * src/display.c (event_callback): double-click timeout is per screen, so get the screen and pass screen->ui to meta_ui_get_double_click_timeout() * src/ui.c (meta_ui_get_double_click_timeout): take a MetaUI argument so we get the right settings for each screen (meta_ui_get_drag_threshold): new function 2003-06-09 Rob Adams <robadams@ucla.edu> Revamp placement policy for windows that are maximized when they are mapped, including windows that set a hint to be maximized or windows that are auto-maximized using our heuristic. See #111902. * src/window.h: add new flag maximize_after_placement and new function meta_window_maximize_internal. * src/window.c (meta_window_new): initialize maximize_after_placement to FALSE and remove the automaximize heuristic. (meta_window_maximize_internal): new function accepts a saved_rect argument to be used as the new saved_rect for the window, and does not queue a move_resize. (meta_window_maximize): re-implement using meta_window_maximize_internal. (update_net_wm_state): If a window has a maximize hint set on startup set maximize_after_placement to TRUE * src/constraints.c (meta_window_constrain): Update the xinerama information in the ConstraintInfo after placing the window, and maximize the window after placement if window->maximize_after_placement * src/place.c (find_first_fit): take a natural xinerama list as an argument instead of generating it here (constrain_placement): remove function, since it is no longer needed (meta_window_place): generate the natural xinerama list here and pass it into find_first_fit. If find_first_fit fails, use the list to find empty xineramas where we can place windows that may be maximized later. This makes maximized windows follow the correct placement policy. Move the automaximize heuristic here. 2003-06-09 Rob Adams <robadams@ucla.edu> * src/metacity-dialog.c (warn_about_no_sm_support): install an alarm to timeout the no-sm-dialog after 4 minutes of inactivity. Patch from Ximian. See #114789. 2003-06-07 Rob Adams <robadams@ucla.edu> * src/window.c (meta_window_new): call meta_group_compute_group after setting window->desc to avoid SIGSEGV when verbose mode is enabled. 2003-06-07 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_notify_focus): drop the mouse button grabs for the focused window; we'll see if this breaks anything.

See Bug #96973 * src/window.h: change cached_group variable to group * src/window.c (meta_window_new): change cached_group to group and call meta_window_compute_group * src/groups.c (meta_window_get_group): simply return window->group rather than computing it and returning window->cached_group (meta_window_compute_group): new function computes window->group. Designed to be called once from meta_window_new (remove_window_from_group): change cached_group to group (meta_window_group_leader_changed): call meta_window_compute_group instead of meta_window_get_group 2003-05-29 Rob Adams <robadams@ucla.edu> Use a new property _METACITY_SENTINEL to eliminate a race condition that causes focus to behave badly with sloppy/mouse focus when lots of windows are mapped/unmapped, such as with a workspace switch. The EnterNotify events on a display are ignored until the PropertyNotify sent after all the window maps is received. This is a fix for #110970. * src/display.[ch]: New _METACITY_SENTINEL atom. (event_callback): ignore EnterNotify if the sentinel isn't clear, and decrement the sentinel counter when the PropertyNotify is received. (meta_display_increment_focus_sentinel): new function.

(meta_display_focus_sentinel_clear): returns whether the sentinel counter is zero. * src/window.c (idle_calc_showing): after showing windows, call meta_display_increment_focus_sentinel on each display for windows to be shown. * src/workspace.[ch] (meta_workspace_activate_with_focus): new function activates a workspace and focuses a particular window after the workspace is activated. (meta_workspace_activate): now just a wrapper for meta_workspace_activate_with_focus * src/keybindings.c: use new meta_workspace_activate_with_focus function to ensure that focus will follow the focused window through the workspace switch. 2003-05-29 Havoc Pennington <hp@redhat.com> * src/theme-parser.c (meta_theme_load): s/int/gsize/ for g_file_get_contents() (found independently by marcus@freebsd.org on SPARC and James Laska on s390x; #113661 * src/main.c (main): fix theme location mentioned in error message 2003-05-29 Ray Strode <halfline@hawaii.rr.com> Get and use double-click speed from GtkSettings (Bug #103218). * src/ui.c, src/ui.h: add function meta_ui_get_double_click_timeout for looking up the global double-click speed. * src/display.c, src/display.h: remove double_click_time field from MetaDisplay and use meta_ui_get_double_click_timeout instead. 2003-05-29 Rob Adams <robadams@ucla.edu> * src/main.c (main): chdir to the user's home directory on startup. See #113755. * src/stack.c (get_standalone_layer): a window should be in the fullscreen layer if it or any of its transient descendants are focused or expecting the focus and it is either fullscreen or fullscreen sized. Fix for #104369. * src/stack.c (is_focused_foreach): foreach used by get_standalone_layer to find focused transient descendants. 2003-05-20 Havoc Pennington <hp@pobox.com> * src/keybindings.c (meta_change_keygrab): the mask display->ignored_modifier_mask wasn't being bound, due to "<" instead of "<=" (most people didn't notice as display->ignored_modifier_mask included Scroll_Lock).

Fixes #95747. 2002-10-12 Havoc Pennington <hp@pobox.com> * src/metacity.schemas.in: button layout key * src/prefs.c: Add button layout gconf key (change_notify): use some "else if" instead of "if" where we should have been 2002-10-11 Havoc Pennington <hp@redhat.com> * src/display.c (event_callback): don't raise window on button 2 click, only on button 1 and button 3. * src/frames.c (meta_frames_button_press_event): lower on button 2 press on frame * src/core.c (meta_core_user_lower): new function 2002-10-11 Havoc Pennington <hp@pobox.com> * src/stack.c (window_is_fullscreen_size): make the checks here allow windows larger than the screen in addition to exactly-screen-size * src/window.c (meta_window_configure_request): delete the "try to auto-enter-fullscreen-state" hack here, because it was broken, and the changes to the stacking code to move screen-size focused windows to the fullscreen layer should work better. (meta_window_new): remove auto-fullscreen hack from here too 2002-10-09 Havoc Pennington <hp@pobox.com> * src/stack.c (apply_constraints): also keep utility/menu/toolbar windows above their whole group. (get_standalone_layer): don't use META_LAYER_FOCUSED_WINDOW, but only use META_LAYER_FULLSCREEN while the fullscreen window has focus. Also, put screen-sized windows in the fullscreen layer, even if we didn't dare to actually put them in the fullscreen state. 2002-10-07 Havoc Pennington <hp@redhat.com> Add a modifier key preference for the Alt+click stuff. Can be set to "disabled" as well. * src/run-metacity.sh: load .Xmodmap in the Xnest if it exists * src/display.c (meta_display_ungrab_window_buttons): ungrab AnyModifier in case the modifier changed since we grabbed (meta_display_open): rearrange code to use meta_display_close() to mop up when we can't find any screens, avoiding the need to keep the bail-out code in sync with meta_display_close. * src/keybindings.c (devirtualize_modifiers): move this function to a public place in display.c * src/metacity.schemas.in: add setting for the modifier key to use for Alt+left/middle/right click. * src/prefs.c (update_binding): add a missing newline to a warning (meta_prefs_get_mouse_button_mods): new function * src/ui.c (meta_ui_parse_modifier): new function 2002-10-07 Havoc Pennington <hp@pobox.com> * src/async-getprop.c: don't include unportable Xproto.h, fix from Glynn Foster. 2002-10-06 Havoc Pennington <hp@pobox.com> * src/async-getprop.c: change to add only one _XAsyncHandler per display, speeding things up a bit. 2002-10-06 Havoc Pennington <hp@pobox.com> * src/async-getprop.c: Add wacky hack suggested by Keith Packard to get X properties asynchronously. Not actually used by metacity yet, but thinking about it. 2002-10-04 Havoc Pennington <hp@redhat.com> * configure.in: actually link to RANDR_LIBS 2002-10-04 Havoc Pennington <hp@redhat.com> * src/display.c (event_callback): do XRRUpdateConfiguration() if we have RandR extension, else poke in Xlib's screen struct to update the screen size. * configure.in: fix a bogus overwrite of cppflags, add a check for RandR extension 2002-10-04 Arvind Samptur <arvind.samptur@wipro.com> * src/window.c (meta_window_change_workspace): call meta_window_unstick before adding window to workspace. (menu_callback): call meta_workspace_activate before meta_window_change_workspace. This would avoid us running an extra loop for determining the window workspace list. Patches from Jeyasudha and Arvind. Fixes #92575 2002-10-03 Havoc Pennington <hp@pobox.com> * src/themes/Esco/metacity-theme-1.xml: only specify the middle backgrounds, let left/right fall back to middle * src/theme.c (get_button): fall back to middle_background draw routines when missing the left/right button backgrounds. (button_rect): fix to handle drawing middle button backgrounds (meta_frame_style_draw): draw middle background once per middle button 2002-10-03 Havoc Pennington <hp@pobox.com> Button-reordering patch. Has all the code except actually installing a gconf schema and reading the gconf key in prefs.c. metacity-theme-viewer displays the button layouts for testing themes. * src/preview-widget.c (meta_preview_size_request): make up a width/height if no child widget * src/prefs.c (meta_prefs_get_button_layout): new function * src/frames.c: get the button layout from prefs and use it when drawing * src/theme.c (meta_frame_layout_calc_geometry): enhance to be able to lay out buttons in different arrangements (button_rect): draw the new button background rectangles (meta_theme_draw_frame): require a button layout argument (meta_theme_calc_geometry): pass in the button layout * src/preview-widget.h: mod to handle button layouts * src/theme-viewer.c: mod to handle button layouts 2002-10-03 Havoc Pennington <hp@redhat.com> * configure.in: 2.4.2 2002-10-03 Havoc Pennington <hp@redhat.com> * src/window.c (check_moveresize_frequency): handle the case where the clock is set backward 2002-10-01 Havoc Pennington <hp@pobox.com> * src/place.c (find_next_cascade): try extra cascades alongside the first, if the first fails; patch from readams@hmc.edu 2002-10-01 Havoc Pennington <hp@pobox.com> * src/stack.c (get_standalone_layer): put ABOVE windows in same layer as docks. 2002-10-01 Havoc Pennington <hp@pobox.com> * src/screen.c (meta_screen_resize_func): make it static * src/stack.c (get_standalone_layer): put above/below windows in an appropriate layer. * src/screen.c (set_supported_hint): say we support above/below * src/display.h (struct _MetaDisplay): add _NET_WM_STATE_ABOVE, _NET_WM_STATE_BELOW atoms * src/window.c (meta_window_client_message): handle above/below state messages (set_net_wm_state): handler above/below state (update_net_wm_state): handle above/below states 2002-10-01 Mark McLoughlin <mark@skynet.ie> * src/screen.c: (meta_screen_new): default to topleft starting corner. (meta_screen_update_workspace_layout): handle new property format : orient,x,y,starting corner. Fixes #89373. * src/screen.h: add MetaScreenCorner enum. 2002-10-01 Havoc Pennington <hp@pobox.com> * src/window.c (constrain_position): always align fullscreen windows to top, as we do with maximized windows. 2002-10-01 Stanislav Brabec <sbrabec@suse.cz> * configure.in: Added cs to ALL_LINGUAS. 2002-09-30 Havoc Pennington <hp@pobox.com> * src/screen.c (reload_xinerama_infos): fix compilation on Solaris, patch from Satyajit Kanungo 2002-09-29 Havoc Pennington <hp@pobox.com> * src/eggaccelerators.c: update from libegg to get fix from Ralph Loader for <Super> <Hyper> <Meta> parsing, #93005 2002-09-29 Havoc Pennington <hp@pobox.com> * src/effects.h (META_MINIMIZE_ANIMATION_LENGTH): shorten minimize animation a bit 2002-09-28 Havoc Pennington <hp@pobox.com> Patch from Keith Packard to handle root window resizes. * src/screen.c (reload_xinerama_infos): factor out Xinerama code (meta_screen_resize): implement this, to be called from display.c on screen resize * src/display.c (event_callback): handle ConfigureNotify on root windows 2002-09-28 Havoc Pennington <hp@pobox.com> * src/stack.c (get_standalone_layer): re-enable the FOCUSED_WINDOW layer, should now work correctly. 2002-09-28 Havoc Pennington <hp@pobox.com> * src/window.c, src/stack.c: Rewrite stack code to work a lot differently. Should be better now, and not lose relative positions of windows when moving among layers. Also should now be possible to get session management to restore the stacking order. Probably breaks some stuff, and makes all the stack.c changes I made yesterday sort of irrelevant. 2002-09-27 Havoc Pennington <hp@pobox.com> * src/stack.c (get_standalone_layer): Temporarily disable use of the FOCUSED_WINDOW layer, because given the fact that moving multiple windows into the same layer changes the Z-order of those windows, it was breaking click-to-focus. 2002-09-27 Havoc Pennington <hp@pobox.com> * src/screen.c (meta_screen_focus_top_window): raise the focused window, since it may not be the window on top, given the below change. * src/stack.c (meta_stack_get_default_focus_window): make this more complex to prefer to focus the transient parent, followed by other windows in group, followed by topmost non-dock, followed by dock. Previously was just topmost non-dock followed by dock ignoring groups and transiency. 2002-09-27 Havoc Pennington <hp@pobox.com> * src/place.c (constrain_placement): constrain placement to try to keep windows from going offscreen to the right/bottom * src/stack.c (compute_layer): rearrange the logic here to say that a window must always be in at least as high a layer as any of its transient parents or group members, rather than special-casing fullscreen. Also, group_member_is_fullscreen was leaking the list of group members every time, a fairly major memory leak. 2002-09-27 Havoc Pennington <hp@redhat.com> * src/themes/Makefile.am (THEMES): use AgingGorilla not Gorilla (renamed on the CVS server) 2002-09-27 Havoc Pennington <hp@redhat.com> Try to handle Solaris Xinerama, all coded blind, someone on Solaris will need to debug the typos. * src/display.c: updates for Solaris Xinerama * src/screen.c: updates for Solaris Xinerama * configure.in: make Xinerama check more complicated to catch Solaris Xinerama 2002-09-27 Havoc Pennington <hp@redhat.com> * src/window.c (update_transient_for): keep a flag transient_parent_is_root_window for whether the root-window-as-parent convention was used. 2002-09-25 Arvind Samptur <arvind.samptur@wipro.com> * src/stack.c (sort_window_list): Keep dialogs without transient parent above entire app. Fixes #88926 2002-09-26 Havoc Pennington <hp@pobox.com> * src/menu.c (meta_window_menu_new): use MetaAccelLabel to display accelerators for the menu items * src/metaaccellabel.c: cut-and-paste GtkAccelLabel and port to use virtual modifiers * src/Makefile.am (metacity_SOURCES): add metaaccellabel.[hc] * src/prefs.c (meta_prefs_get_window_binding): new function * src/core.c (meta_core_get_menu_accelerator): new function 2002-09-25 Havoc Pennington <hp@redhat.com> * src/metacity.schemas.in: Change short desc of switch_windows and cycle_windows to be different 2002-09-24 Havoc Pennington <hp@pobox.com> * src/place.c (fit_rect_in_xinerama): update best_overlap as we go through the loop - doh.

Patch from Jeyasudha. Fixes #91944. 2002-09-19 Arvind Samptur <arvind.samptur@wipro.com> * src/tools/metacity-properties.desktop.in : change in the tooltip suggested in ui-review. 2002-09-18 Havoc Pennington <hp@redhat.com> * src/window.c (update_net_wm_state): handle fullscreen state here. 2002-09-15 Havoc Pennington <hp@pobox.com> * src/session.c (save_state): escape the window title before saving in the session file, reported by Jos Vos 2002-09-12 Havoc Pennington <hp@redhat.com> * src/workspace.c (meta_workspace_screen_index) (meta_workspace_index): fix compiler warnings * src/tools/metacity-window-demo.c (menu_items): add a test for dialogs with no transient parent * src/place.c (find_first_fit): Try placing window at origin of first Xinerama, even if there are no windows to place next to; makes placement work when no other windows are open on the screen. 2002-09-09 Havoc Pennington <hp@pobox.com> * configure.in: 2.4.1 2002-09-09 Christian Neumair <chris@gnome-de.org> * src/keybindings.c: Make virtual desktops apply instantly and still show the pager popup by Benjamin Kahn <xkahn@zoned.net>, fixes #86590. 2002-09-06 Frederic Crozat <fred@crozat.net> * src/themes/Crux/metacity-theme-1.xml: Fix titlebar glitch on small dialogs. 2002-09-06 Arvind Samptur <arvind.samptur@wipro.com> * theme-format.txt : corrected some of the attributes which were not in sync with theme-parser.c Patch from Jim Bowen. #92057. 2002-09-05 Havoc Pennington <hp@pobox.com> * configure.in: put ro back in ALL_LINGUAS 2002-09-05 Havoc Pennington <hp@redhat.com> * configure.in (ALL_LINGUAS): remove 'ro' from ALL_LINGUAS, it contained invalid XML and broke the build.

Take a "mask" argument to avoid ambiguity issues. * src/keybindings.c (handle_workspace_switch): rename from handle_workspace_forward since there's no directionality here (handle_workspace_switch): add a FIXME about how screwed it is that we need a window in order to do our grab. Should be able to grab on a dummy window like no_focus_window or the root window.

Thought it might fix metacity-window-demo but it didn't. * src/window.c (constrain_size): only get work area when needed (meta_window_new): init the do_not_cover field 2002-06-08 Havoc Pennington <hp@pobox.com> * src/screen.c (meta_screen_get_xinerama_for_window): short-circuit the "only one xinerama" case, and use outer rect of window instead of window->rect, so we get root window coords. * src/theme.c (meta_frame_layout_get_borders): if fullscreen all frame edges are zero-width. * src/frame.c (meta_frame_get_flags): init fullscreen flag. * src/common.h (enum): add META_FRAME_FULLSCREEN frame flag * src/place.c: fix up calls to meta_window_get_work_area * src/window.c (meta_window_get_work_area): add an arg for whether the work area is for the screen or the xinerama subscreen. (constrain_position): fix up calls to meta_window_get_work_area (constrain_size): ditto * src/screen.c (meta_screen_new): add METACITY_DEBUG_XINERAMA environment variable which simulates xinerama on a single head. 2002-06-08 Havoc Pennington <hp@pobox.com> * src/window.c (update_struts): only invalidate things if the struts actually change, since the panel likes to set them over and over.

We do allow these windows to be focused (so keynav works), but they don't get focused automatically. Now how do we keep them out of the task list? 2002-06-04 Gustavo GirÃ�¡ldez <gustavo.giraldez@gmx.net> * src/theme.c (draw_op_as_pixbuf): Use icon's instead of image's fill_type when type is META_DRAW_ICON. 2002-06-03 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_new): don't automatically fullscreen things opened fullscreen, because there's no GUI to un-fullscreen them. 2002-06-03 Havoc Pennington <hp@pobox.com> * src/theme-parser.c (parse_aspect_ratio): fix error message about bad aspect ratio name. 2002-06-03 Havoc Pennington <hp@pobox.com> * src/themes/Esco/metacity-theme-1.xml: test button aspect ratio instead of hardcoded button size, James feel free to revert if you don't like it this way. * src/theme-parser.c: parse the aspect_ratio element for button aspect ratios. * src/theme.h (struct _MetaFrameLayout): allow button sizes to be given as an aspect ratio derived from the titlebar height, instead of as a fixed size. * src/theme.c (meta_frame_layout_validate): validate new button sizing parameters * src/theme.c (meta_frame_layout_calc_geometry): use new button layout params Mon Jun 3 15:12:11 2002 HideToshi Tajima <hidetoshi.tajima@sun.com> * configure.in (METACITY_LIBS): put -lXext into SHAPE_LIBS 2002-06-03 Kjartan Maraas <kmaraas@gnome.org> * src/tools/metacity-properties.desktop.in: Someone forgot to mark the two strings in here for translation :) 2002-06-02 Havoc Pennington <hp@pobox.com> * configure.in: 2.3.610 2002-06-01 Havoc Pennington <hp@pobox.com> * src/frames.c (meta_frames_finalize): move the remove_listener to finalize instead of destroy, thanks to Jayaraj for tracking down the bug. 2002-06-01 Havoc Pennington <hp@pobox.com> * src/session.c: add some missing \n (meta_session_init): remove the #if 0 interact callback from our initial SmcOpenConnection call, this arg to SmcOpenConnection doesn't exist. 2002-06-01 Havoc Pennington <hp@pobox.com> * src/session.c: put in more debug spew about the session 2002-05-30 Havoc Pennington <hp@pobox.com> * src/Makefile.am (INCLUDES): use $(prefix)/@DATADIRNAME@/locale for localedir to work with Solaris native gettext, patch from Hidetoshi Tajima * src/tools/Makefile.am: ditto 2002-05-31 Havoc Pennington <hp@redhat.com> * src/theme.c: add MetaImageFillType and implement TILE in addition to the existing SCALE * src/theme.h (struct _MetaDrawOp): remove no-longer-used "alpha" field 2002-05-31 Havoc Pennington <hp@redhat.com> * src/theme.c (multiply_alpha): now just uses meta_gradient_add_alpha (draw_op_as_pixbuf): implement alpha gradients for tint, gradient, and image draw ops, so I can implement garrett's stuff. * src/gradient.c (meta_gradient_add_alpha): new function to multiply the alpha channel of a pixbuf by an alpha gradient 2002-05-30 Havoc Pennington <hp@redhat.com> * src/main.c (main): verbose-log on startup whether we were compiled with various extensions * src/display.c (meta_display_queue_retheme_all_windows): reapply shape mask when changing themes, sucks to do it here though, makes theme changing slower.

(meta_frames_paint_to_drawable): change to take a region argument; punch the client area out of the expose region, then iterate over rectangles in the region and draw each, manually doing begin_paint_rect. Results in 4 long thin backing pixmaps per frame repaint, instead of one large backing pixmap. Suggested by Owen. 2002-05-05 Bastien Nocera <hadess@hadess.net> * src/workspace.c: (meta_workspace_get_neighbor): Wrap-around workspaces (ie. when on the last workspace, "switch_to_workspace_right" goes back to the first one) 2002-05-05 Anders Carlsson <andersca@gnu.org> * src/metacity.schemas: Fix a spelling error and change switch_to_workspace_up and switch_to_workspace_down to use Ctrl+Alt since Nautilus uses Alt now. 2002-05-04 Havoc Pennington <hp@pobox.com> * src/window.c (update_net_wm_type): correctly print things if the type_atom is unset (meta_window_new): with workarounds disabled, always allow self-placement for windows with PPosition or USPosition set. 2002-05-03 Havoc Pennington <hp@redhat.com> * src/Makefile.am: fix for automake 1.5, patch from Tomasz Kloczko 2002-05-03 Laszlo Peter <laca@sun.com> * configure.in: add the X libs to METACITY_MESSAGE_LIBS and METACITY_WINDOW_DEMO_LIBS 2002-05-02 Havoc Pennington <hp@redhat.com> * README: updates * configure.in: 2.3.233 2002-05-02 Bastien Nocera <hadess@hadess.net> * src/metacity.schemas: change the default for switch_to_workspace_* to be <Control><Alt>arrow as just <Alt>arrow collides with some apps (especially web browsers) 2002-05-01 Havoc Pennington <hp@redhat.com> * src/screen.c (meta_screen_new): Xlib doesn't like NULL for out arguments; fix for #80472 from lbedford 2002-04-30 Havoc Pennington <hp@pobox.com> * src/keybindings.c: finish mopping up mode_switch_mask field * src/display.h (struct _MetaDisplay): remove mode_switch_mask field 2002-04-30 Havoc Pennington <hp@pobox.com> * src/window.c (recalc_window_features): don't try to decorate toolbars. * src/tools/metacity-window-demo.c: add menu and toolbar tests * src/place.c (meta_window_place): only dialogs should be centered over parent, not anything with transient for set. * src/window.c (meta_window_configure_request): become more fascist about window positioning if workarounds are disabled, and less fascist if they are enabled. * src/metacity.schemas: add a "disable_workarounds" option. Kind of crack-smoking. But we just can't get all applications fixed. And I need no-workarounds mode to monitor which apps are broken and what needs fixing in specs. * src/window.c (meta_window_configure_request): always allow windows to resize themselves * src/keybindings.c (reload_modmap): don't filter out Mode_switch, apparently some people bind window manager shortcuts to that. 2002-04-30 Havoc Pennington <hp@redhat.com> * src/window.c (constrain_position): oops, fix maximization. Pointed out by Gustavo GirÃ�¡ldez Tue Apr 30 06:24:09 2002 Jonathan Blandford <jrb@gnome.org> * src/menu.c: give Maximize/Unmaximize and Shade/Unshade the same mnemonic for consistency's sake. 2002-04-29 Havoc Pennington <hp@redhat.com> * src/window.c (TITLEBAR_LENGTH_ONSCREEN): require 36 pixels onscreen so you typically get a sliver of titlebar, suggested by tigert.

And they were kind of on crack anyway. 2002-03-17 Havoc Pennington <hp@pobox.com> * src/resizepopup.c (ensure_tick_windows): turn off the tick marks, that got annoying after about 5 minutes. One big shape window instead of lots of little windows might fix it. 2002-03-17 Havoc Pennington <hp@pobox.com> * src/resizepopup.c: Add some total crackrock resize-grid indication for windows that have width_inc/height_inc so I can debug gnome-terminal sizing. 2002-03-17 Havoc Pennington <hp@pobox.com> * src/session.c (set_clone_restart_commands): use proper property name for SmDiscardCommand (instead of setting the clone command to "rm").

Yeah the crack flows freely these days. Everyone knew it would happen. 2002-01-27 Havoc Pennington <hp@pobox.com> * src/frames.c: separate code to draw frame from the expose_event handler, so in principle we can draw the frame to a pixmap, but this isn't used yet. 2002-01-22 Hasbullah Bin Pit <sebol@ikhlas.com> * configure.in: Added Malay (ms)to ALL_LINGUAS. * po/ms.po: Added Malay Translation. 2002-01-19 Havoc Pennington <hp@pobox.com> * src/wm-tester/test-resizing.c: cheesy client with static bit gravity, used to test the below change. * src/window.c (meta_window_move_resize_internal): implement Owen's proposal for window resizing. http://mail.gnome.org/archives/wm-spec-list/1999-November/msg00088.html Currently you have to do METACITY_USE_STATIC_GRAVITY=1 in order to use it, because some GDK bug is screwing up exposes on my frames when it's enabled. * src/display.c (meta_display_create_x_cursor): fix glyph for NE/NW cursors * src/frames.c (get_control): add ability to resize from top * src/frame.c (meta_frame_get_flags): can't resize shaded windows (meta_frame_sync_to_window): add gravity arg * src/common.h (MetaWindowType): move here from window.h so it can be used in themes stuff.

We'll see what breaks. Should be more efficient and reduce flickery stuff a bit in some cases. 2002-01-15 Havoc Pennington <hp@redhat.com> * src/keybindings.c (handle_tab_backward): fix crash when grab failed due to another operation in progress (handle_tab_forward): fix crash when grab failed 2002-01-10 Havoc Pennington <hp@pobox.com> * src/frame.c (meta_window_destroy_frame): only bump unmaps_pending if the window was mapped (meta_window_ensure_frame): ditto * src/keybindings.c: change arrow key bindings to use Ctrl+Alt not just Alt, and add debug mode key bindings * src/stack.c (meta_stack_get_default_focus_window): don't choose a default focus window with unmaps pending, since we probably just unmapped it. * src/display.c (event_callback): move notify_focus on UnmapNotify after the window_free check, so we can move focus to another window when we unmanage * src/window.c (meta_window_hide): invalidate work areas when hiding a window with struts (meta_window_free): invalidate work areas when unmanaging a window with struts 2002-01-09 Havoc Pennington <hp@pobox.com> * src/window.c, src/window.h: store strut information, update it on property changes, etc. etc. so we avoid panel on maximize. * src/workspace.c (meta_workspace_get_work_area): add accessor for work area so we can compute it lazily * src/display.h, src/display.c: add _NET_WM_STRUT atom and _WIN_HINTS atom 2002-01-08 Havoc Pennington <hp@pobox.com> * configure.in (ACLOCAL): add code to save ACLOCAL_FLAGS * src/frames.c (meta_frames_expose_event): max dither * src/testgradient.c (render_simple): change dither mode to MAX to avoid banding * src/theme.c: lose the gradient cache, and put in some initial data types for the theme format 2002-01-07 Havoc Pennington <hp@redhat.com> * src/frames.c (meta_frames_expose_event): make gradient a bit more subtle (don't go to the full background, but to a blend of selection and background; put lighter color on top) 2002-01-06 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_notify_focus): rearrange code a bit to make it clear that has_focus flag always follows display->focus_window 2002-01-06 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_notify_focus): put in attempted fix for the GTK 1.2 plug/socket screwup, now that my fixed debug spew reveals what's actually happening. ;-) * src/gradient.c (meta_gradient_description_new): object to store gradient descriptions * src/window.c (meta_window_notify_focus): fix the debug spew that was confusing me * src/wm-tester/focus-window.c: add little program to focus a window ID 2002-01-06 Havoc Pennington <hp@pobox.com> * src/theme.c (meta_theme_get_gradient): change to use spiffy gradient code. * src/gradient.c: copy lovely gradient code from WindowMaker, as usual Dan and Alfredo have very nice code 2002-01-06 Fatih Demir <kabalak@gtranslator.org> * configure.in: Added "tr" to the languages list. 2002-01-05 Havoc Pennington <hp@pobox.com> * src/frames.c (meta_frames_expose_event): draw titlebar highlight with snazzy gradient that needs some tweaking to be less dumb-looking * src/theme.c: replace old theme.[hc] contents with newer stuff that doesn't do anything 2002-01-05 Havoc Pennington <hp@pobox.com> GTK 1.2 plug/socket clients still broken, don't know why. * src/screen.c (meta_screen_new): select focus change on root window, for debugging * src/display.c (event_callback): when unfocusing, use no_focus_window to hold the focus * src/display.h (struct _MetaDisplay): have a no_focus_window to hold the focus when we don't want to have anything focused. Then we can avoid confusing focusing-the-frame stuff. * src/window.c (meta_window_notify_focus): improve some debug spew (meta_window_notify_focus): add hack from WindowMaker to ignore focus in events with detail > NotifyNonlinearVirtual 2002-01-04 Havoc Pennington <hp@pobox.com> * src/display.c (event_callback): don't lower docks when a grab causes them to get LeaveNotify 2002-01-04 Havoc Pennington <hp@pobox.com> * src/screen.c (meta_screen_free): set event mask on root window to 0 so other window managers (such as ourselves restarting) can start up; addresses race condition on restart where the old WM still had RedirectMask when the new WM was trying to start up. * src/display.c (meta_display_close): free each screen * src/window.c (meta_window_show): always focus new windows in click-to-focus mode 2002-01-03 Havoc Pennington <hp@pobox.com> * src/window.c: use meta_XFree not XFree * src/display.h (meta_XFree): add null-safe XFree * src/util.c (meta_warning): have message prefix indicate that it's a warning (meta_fatal): indicate it's an error * src/window.c (update_sm_hints): clean up using meta_prop_get_latin1_string (update_role): ditto (read_client_leader): clean up using meta_prop_get_window (update_net_wm_type): clean up using meta_prop_get_cardinal (update_initial_workspace): ditto (update_net_wm_type): clean up using meta_prop_get_atom_list (read_rgb_icon): get result from XGetWindowProperty return value not from error trap (update_kwm_icon): ditto (meta_window_new): fix to read WM_STATE correctly 2002-01-03 Havoc Pennington <hp@pobox.com> * src/window.c (update_net_wm_state): clean up using meta_prop_get_atom_list (update_mwm_hints): clean up using meta_prop_get_motif_hints * src/Makefile.am (metacity_SOURCES): add xprops.[hc] * src/xprops.c: new file with convenience functions for X properties 2002-01-03 Havoc Pennington <hp@pobox.com> * src/workspace.c (meta_workspace_activate): focus top window when switching to a new workspace * src/util.c (meta_topic): start putting verbose output in categories * src/window.c (meta_window_shade): focus frame after we queue the calc_showing so the maps/unmaps have already happened. * src/display.c (meta_display_get_current_time): add the "get time of current event" function and call it occasionally. * src/window.c (meta_window_free): if we have focus, call meta_screen_focus_top_window().

Disadvantage is all left-button clicks now require window manager approval. ;-) * src/display.c (event_callback): don't focus dock/desktop when the mouse enters them; require a click. (meta_change_button_grab): allow sync grabs (meta_display_grab_unfocused_window_buttons): establish a synchronous grab and maintain it all the time, rename to meta_display_grab_focus_window_button * src/window.c: change to reflect display.c 2001-12-10 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_update_unfocused_button_grabs): oops, unbreak this _again_ - reported by Josh Barrow 2001-12-10 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_update_unfocused_button_grabs): don't allow grab on docks/desktop for now; needs fixing later to do the grab, but pass thru click, so we can focus those windows.

Implement unfocusing on LeaveNotify in mouse focus mode. Click to focus just ends up working if we do nothing on enter/leave, because of the way things already worked. Except I need to add some relatively complex hack to allow clicking on client area, right now you have to click on the frame. 2001-12-09 Havoc Pennington <hp@pobox.com> * src/main.c (main): move SM init a bit later in the process, and init prefs * src/session.c: fix no SM case (though I hardly know why I'm bothering) * src/main.c (main): call bindtextdomain * src/util.h (_): actually call gettext * configure.in: put in AM_GLIB_GNU_GETTEXT and gconf stuff * src/prefs.c: Preferences - this marks the beginning of our doom. None of them are actually implemented yet, but we monitor some stuff from gconf. 2001-12-07 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_unminimize): when unminimizing an app, if we're in "show desktop" (all windows minimized) mode, leave show desktop mode. Will occasionally be a bit weird, but allows people to recover via task list if they accidentally do the show desktop thing, and don't know what's going on. 2001-12-06 Havoc Pennington <hp@redhat.com> * src/ui.c (meta_text_property_to_utf8): fix gdkatom/xatom screwup - gee, I should read my warnings 2001-12-03 Laszlo Peter <laca@ireland.sun.com> * src/frames.c: add a dummy element to the enum so the signals array is not empty. (breaks the build with Forte C) * src/window.c: s/__FUNCTION__/G_GNUC_FUNCTION/ 2001-11-27 Havoc Pennington <hp@pobox.com> * src/window.c (constrain_position): change so that window can be offscreen to the bottom or the right, as long as a small top-left corner of the window remains onscreen.

Fixes bugs such as pinned windows not appearing in the tab order. (meta_window_client_message): use meta_window_visible_on_workspace * src/stack.c (find_tab_forward): ditto (find_tab_backward): ditto (meta_stack_get_tab_next): ditto (meta_stack_get_tab_list): ditto * src/place.c (get_windows_on_same_workspace): ditto * src/keybindings.c (handle_focus_previous): ditto (handle_focus_previous): ditto 2001-10-24 Havoc Pennington <hp@pobox.com> * src/frames.c (meta_frames_expose_event): use bg/fg not base/text for the window title area. 2001-10-24 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_new): support initial on-all-workspaces setting 2001-10-22 Havoc Pennington <hp@pobox.com> * src/stack.c (meta_stack_sync_to_server): fix to keep desktop window from appearing on top of everything else, among other stack bugs. Untested. 2001-10-15 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_new): use queried attributes to check whether window should be initially maximized, rather than window rect 2001-10-15 Havoc Pennington <hp@pobox.com> * src/main.c (meta_restart): add a restart feature, for debugging * src/tools/metacity-restart.c: little utility program to trigger the restart 2001-10-14 Havoc Pennington <hp@pobox.com> * src/frames.c (meta_frames_button_press_event): raise/focus windows on left-click, seem to have broken that yesterday * src/keybindings.c, src/display.c, src/window.c: add keybinding to show/hide all normal windows (so you can see the desktop). Currently Ctrl+Alt+D, which I don't like, but yay. 2001-10-14 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_new): take a window mapped at fullscreen size/pos to desire maximization; once I add a fullscreen state, will change to copy kwin and take this mapping as a desire for fullscreen, but for now testing with maximization. * src/window.h: remove fullscreen window type, now proposing it as a window state instead. 2001-10-14 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_maximize): always raise windows on maximize (meta_window_client_message): when activating a window, move it to current workspace, instead of moving user to the window's workspace. 2001-10-14 HÃ�©ctor GarcÃ�­a Ã�lvarez <hector@scouts-es.org> * configure.in: Added "es" to ALL_LINGUAS for Spanish translation. 2001-10-14 Havoc Pennington <hp@pobox.com> * src/display.c (event_callback): only handle events here if the modmask from our button grab is active. i.e. only the Alt-click is handled here. * src/frames.c: add check for whether button presses are in the frame client area before handling them, so we don't weirdly let you move a frame by clicking in its client area if the client hasn't selected button press events. 2001-10-13 Havoc Pennington <hp@pobox.com> * src/stack.c (meta_stack_sync_to_server): set last window before setting newp, so we don't get the current window as the last window and screw everything up (IN_TAB_CHAIN): use type not layer to decide if a window is in the tab chain, keeps panel out of alt-tab choices 2001-10-13 Havoc Pennington <hp@redhat.com> * configure.in: add bad hack to work with GTK 1.3.9.90 RPMs from gnomehide for now * src/ui.c: another piece of bad hack in here 2001-10-13 Havoc Pennington <hp@redhat.com> * configure.in: bump version 2001-10-13 Havoc Pennington <hp@pobox.com> * src/session.c (meta_session_init): hmm, fix build 2001-10-12 Havoc Pennington <hp@pobox.com> * src/session.c (meta_session_init): set the session manager priority so we start up before other apps. 2001-10-12 Mikael Hallendal <micke@codefactory.se> * src/ui.c (meta_ui_get_default_window_icon): use gdk_pixbuf_new_from_inline (meta_ui_get_default_mini_icon): use gdk_pixbuf_new_from_inline 2001-10-11 Christian Rose <menthos@menthos.com> * configure.in: Added "sv" to ALL_LINGUAS. 2001-10-10 Havoc Pennington <hp@pobox.com> * src/stack.c (meta_stack_free): fix mem leak of the MetaStack object (meta_stack_sync_to_server): try to avoid the restack-flicker thing 2001-10-07 Havoc Pennington <hp@pobox.com> * src/display.c (meta_display_update_active_window_hint): set _NET_ACTIVE_WINDOW hint * src/window.c (meta_window_client_message): support _NET_ACTIVE_WINDOW client message 2001-10-07 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_client_message): don't allow shade/maximize/minimize for windows that don't support those operations. (minimizing the panel = bad) 2001-10-04 Havoc Pennington <hp@pobox.com> * src/keybindings.c (meta_change_keygrab): add code to grab all modifier combinations, so keybindings work with NumLock etc. * src/menu.c (meta_window_menu_new): remove newlines from menu items 2001-09-27 Havoc Pennington <hp@pobox.com> * src/session.c (save_state): when encoding text for session file, escape XML entities 2001-09-21 Alex Graveley <alex@ximian.com> * src/Makefile.am (metacity_SOURCES): Add inlinepixbufs.h so that it gets generated. * src/frames.c (meta_frames_style_set): Update for new opaque PangoFontMetrics. 2001-09-17 Havoc Pennington <hp@pobox.com> * src/ui.c (meta_ui_init): add hackaround for the warning about gtk-menu-bar-accel 2001-09-17 Havoc Pennington <hp@pobox.com> * src/ui.c (meta_ui_get_default_mini_icon): (meta_ui_get_default_window_icon): ref the returned icon, oops. * src/main.c (main): get the GLib warning/error output into the metacity logfile, set warnings to be always fatal * configure.in: bump version to 2.3.13 * src/window.c (get_text_property): hrm, fix bug where we didn't check errors on XGetTextProperty 2001-09-17 Havoc Pennington <hp@pobox.com> * src/Makefile.am (VARIABLES): fix srcdir != builddir glitch 2001-09-17 Havoc Pennington <hp@pobox.com> * src/ui.c: use the inline image data for default icon * src/common.h (META_MINI_ICON_HEIGHT): move icon size defines here * src/Makefile.am: Create an inlinepixbufs.h header with inline images 2001-09-16 Havoc Pennington <hp@pobox.com> * src/session.c (process_ice_messages): disconnect this callback on error 2001-09-16 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_lower): new function * configure.in: bump version to 2.3.8 * src/display.c (event_callback): raise dock on enter notify, lower it on leave notify (need to refine this behavior) * src/stack.c (compute_layer): experiment with putting the panel in the normal layer, and raising it on mouseover 2001-09-15 Havoc Pennington <hp@pobox.com> * src/window.c: add support for a mini icon in the titlebar (update_icon): re-enable support for _NET_WM_ICON * src/session.c (save_state): add an ferror check when writing session file 2001-09-11 Havoc Pennington <hp@pobox.com> * src/main.c (usage): exit with error code on usage() (kind of wrong for --help, but oh well). 2001-09-11 Havoc Pennington <hp@pobox.com> * src/window.c: fix up handling of text properties, so we get UTF8_STRING as that type and not as text list, and so we properly convert from text list to UTF-8 2001-09-10 Havoc Pennington <hp@pobox.com> * src/menu.c (meta_window_menu_new): icon for unmaximize * src/ui.c (meta_ui_init): fix call to XDisplayName * src/util.c: add missing header * src/frames.c: draw an unmaximize control if already maximized 2001-09-10 Havoc Pennington <hp@pobox.com> * src/window.c: Don't separate user_has_moved/user_has_resized, fixes bug in east-resizing Emacs, among other things * src/frame.c (meta_frame_sync_to_window): return immediately if nothing to do * src/util.c (ensure_logfile): replace rather than truncate old logfiles 2001-09-08 Havoc Pennington <hp@pobox.com> * src/ui.c (meta_ui_init): don't use gdk_display_name * src/frame.c (meta_window_ensure_frame): create frame with screen default visual, rather than client window visual; for DRI games, the client window visual was not allowed to be a child of another window with the same visual, apparently. Anyhow now we copy twm, etc. so it must be correct. * src/place.c (meta_window_place): if a transient is placed and its parent has focus, focus the transient. 2001-09-06 Havoc Pennington <hp@pobox.com> * configure.in: bump version 2.3.5, require newer GTK release 2001-09-04 Havoc Pennington <hp@pobox.com> * src/wm-tester/Makefile.am (noinst_PROGRAMS): make test apps noinst * src/metacity.desktop: for the capplet * src/Makefile.am: add .desktop file 2001-09-01 Havoc Pennington <hp@pobox.com> * src/errors.c: clean up the code, and replace GDK X error handler with one that chains up to GDK but first logs the error to logfile. 2001-08-31 Havoc Pennington <hp@pobox.com> * src/tabpopup.c (meta_ui_tab_popup_new): fix args to gtk_alignment_new() 2001-08-29 Havoc Pennington <hp@pobox.com> * src/display.c (event_callback): avoid focusing a window on tab popup popdown * src/screen.c (meta_screen_ensure_tab_popup): compute frame outline size here 2001-08-29 Havoc Pennington <hp@redhat.com> * src/tabpopup.c: Switch back to outline. 2001-08-29 Havoc Pennington <hp@pobox.com> * src/tabpopup.c: experiment with window-cover-with-icon instead of just the outline; can't decide. 2001-08-29 Havoc Pennington <hp@pobox.com> * src/tabpopup.c: add crackrock window-outlining feature * src/session.c (window_type_to_string): handle fullscreen 2001-08-29 Havoc Pennington <hp@pobox.com> * src/display.c (meta_display_open): wrong atom name - _NET_SUPPORTED not _NET_WM_SUPPORTED * src/window.c (meta_window_configure_request): geez, why were we honoring configure requests for width/height for normal windows. Denied! (meta_window_client_message): _NET_WM_MOVERESIZE support, sort of (doesn't quite work, acts like owner_events = true?) * src/display.c: add _NET_WM_MOVERESIZE atom 2001-08-28 Havoc Pennington <hp@pobox.com> Unbreak tab popup a bit. * src/stack.c (meta_stack_get_tab_list): add workspace argument (meta_stack_get_tab_next): add workspace argument * src/window.c: implement recording of the last user-initiated window position, so we can magically handle moving panels around really nicely. * src/wm-tester/main.c (set_up_icon_windows): fix to use new GTK API 2001-08-24 Havoc Pennington <hp@pobox.com> * src/window.c (constrain_position): force fullscreen windows to be at 0,0 * src/ui.c: use NULL colormap to get bitmaps, requires very latest GTK from CVS or it will spew warnings and not work. * src/window.c (constrain_size): disallow larger than screen in all cases, even if user has performed a resize operation. (constrain_position): keep window boxed onscreen. * src/keybindings.c (meta_display_process_key_event): revert an earlier change that disabled global keybindings when a grab is in effect; instead, only disable global keybindings if a _keyboard_ grab is in effect. The earlier change was just a broken workaround, the problems it fixed should have been solved by the addition of XGrabKeyboard() on the metacity keyboard grabs. This should fix the problem with pick-up-window-and-move-to-another-desktop. 2001-08-23 Havoc Pennington <hp@pobox.com> * src/window.c (update_icon): attempt to use the mask as well as the pixmap. Probably doesn't work so well. * src/tabpopup.c: make this look a little nicer 2001-08-22 Havoc Pennington <hp@pobox.com> * src/window.c (update_mwm_hints): all the MWM flag tests were backward 2001-08-22 Havoc Pennington <hp@pobox.com> * src/window.c (update_icon): half-ass implementation of getting pixmap icons (WM_NORMAL_HINTS and KWM_WIN_ICON). Ignores mask for now, with possibly ugly results for some apps. (read_rgb_icon): fixage 2001-08-19 Havoc Pennington <hp@pobox.com> * src/window.c: add a "fullscreen" semantic type; if a window requests the screen size exactly, and is undecorated, and is not a desktop window, we consider it a fullscreen window and keep it on top. Totally untested. 2001-08-19 Havoc Pennington <hp@pobox.com> * src/screen.c (set_supported_hint): we support _NET_WM_ICON * src/wm-tester/main.c: add stuff to test _NET_WM_ICON (but it doesn't work, so it isn't tested yet) * src/window.c (update_icon): read _NET_WM_ICON * src/screen.c (meta_screen_new): set the WM_ICON_SIZE hint * src/tabpopup.c (meta_ui_tab_popup_select): remove assertion * src/window.c (meta_window_get_icon_geometry): fix obscure memleak 2001-08-19 Havoc Pennington <hp@pobox.com> * src/display.c (meta_display_grab_window_buttons): remove XSync, error traps already do that (meta_display_grab_window_buttons): implement * src/keybindings.c: src/display.c: wire up the tab window, it rulez! 2001-08-19 Havoc Pennington <hp@pobox.com> * src/tabpopup.c: add prototype thingy to display windows we're cycling through with tab. Not wired up to keybindings yet. 2001-08-18 Havoc Pennington <hp@pobox.com> * src/effects.c (meta_effects_draw_box_animation): put an XFlush() right after starting things moving 2001-08-18 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_configure_request): (meta_window_move_resize_internal): Make a half-hearted not-very-tested attempt to handle window resizes correctly with respect to window gravity. 2001-08-18 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_get_gravity_position): hrm, I fixed this wrong the other day. Fixes static gravity when moving windows. 2001-08-18 Havoc Pennington <hp@pobox.com> * src/ui.c (meta_image_window_set_position): also set the current size. Lame hack of the day. * src/effects.c (effects_draw_box_animation_timeout): use the delay exposes feature to avoid the screen dirt * src/ui.c (meta_ui_push_delay_exposes): (meta_ui_pop_delay_exposes): feature to let us delay redraws until after we do server-grabbed draw-on-inferiors effects 2001-08-17 Havoc Pennington <hp@redhat.com> * src/window.c (meta_window_get_gravity_position): fix for StaticGravity 2001-08-09 Havoc Pennington <hp@pobox.com> * src/window.c (meta_window_configure_request): Honor USPosition even post-map. I know I'll regret this. 2001-08-07 Havoc Pennington <hp@pobox.com> * src/display.c (meta_display_open): set _NET_WM_NAME hint as a UTF8_STRING not STRING. Patch from Anders. 2001-08-06 Havoc Pennington <hp@redhat.com> * src/effects.c: disable opaque animations by default, current implementation suXors. 2001-08-06 Havoc Pennington <hp@pobox.com> * src/effects.c (meta_effects_draw_box_animation): Get start time after we do the pixbuf from drawable, so we don't count time spent getting pixbuf from drawable in the animation time. 2001-08-06 Havoc Pennington <hp@pobox.com> * src/effects.c: add opaque minimize/shade feature. The wireframe seemed kind of confusing and unclear from a UI standpoint. I know, I know. The bloat begins here. Also, we don't need to grab the server during opaque min/shade, which has some nice implications. * src/ui.c: Add features to render a window with an image in it, and also wrap pixbuf_from_drawable * src/effects.c (meta_effects_draw_box_animation): modify to be smoother (at least theoretically) by syncing to current time and "dropping frames" as appropriate. * src/window.c (meta_window_shade): draw animation for shading too 2001-08-05 Anders Carlsson <andersca@gnu.org> * src/display.h, src/display.c: Add _NET_WM_ICON_GEOMETRY atom. * src/window.c (meta_window_calc_showing): See if the window has an icon geometry and show a morphing animation from the window's coordinates to the icon's coordinates. (meta_window_get_icon_geometry): New function that fetches a window's icon geometry. * src/Makefile.am: Add effects.[ch]. * src/effects.c: New file with cool effects. 2001-08-03 Havoc Pennington <hp@pobox.com> * src/keybindings.c: Add Alt + left/right arrow to move between workspaces. * src/screen.c (set_wm_check_hint): put property pointing back to itself on the _WIN_SUPPORTING_WM_CHECK window. 2001-08-03 Havoc Pennington <hp@pobox.com> * src/display.c (event_callback): push error trap around configure of withdrawn window, fixes a crash caused by rapidly creating/destroying a window. * src/window.c (recalc_window_features): don't allow shading undecorated windows. * src/wm-tester/main.c: add a program to torture window managers. 2001-08-01 Havoc Pennington <hp@pobox.com> * src/window.c (recalc_window_features): if a window isn't resizeable, turn off maximize function. If min size is equal to max size, turn off resize function. �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/AUTHORS��������������������������������������������������������������������������������0000664�0001750�0001750�00000000041�14211404421�014177� 0����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������Havoc Pennington <hp@redhat.com> �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/clutter/�������������������������������������������������������������������������������0000775�0001750�0001750�00000000000�14211404421�014616� 5����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/clutter/Makefile.am��������������������������������������������������������������������0000664�0001750�0001750�00000003142�14211404421�016652� 0����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������NULL = SUBDIRS = build clutter tests if BUILD_EXAMPLES SUBDIRS += examples endif DIST_SUBDIRS = clutter tests examples build # XXX -

Each #ClutterConstraint can change the * allocation of the actor to which they are applied by overriding the * #ClutterConstraintClass.update_allocation() virtual function. * * #ClutterConstraint is available since Clutter 1.4 * * ## Using Constraints * * Constraints can be used with fixed layout managers, like * #ClutterFixedLayout, or with actors implicitly using a fixed layout * manager, like #ClutterGroup and #ClutterStage. * * Constraints provide a way to build user interfaces by using * relations between #ClutterActors, without explicit fixed * positioning and sizing, similarly to how fluid layout managers like * #ClutterBoxLayout and #ClutterTableLayout lay out their children. * * Constraints are attached to a #ClutterActor, and are available * for inspection using clutter_actor_get_constraints(). * * Clutter provides different implementation of the #ClutterConstraint * abstract class, for instance: * * - #ClutterAlignConstraint, a constraint that can be used to align * an actor to another one on either the horizontal or the vertical * axis, using a normalized value between 0 and 1. * - #ClutterBindConstraint, a constraint binds the X, Y, width or height * of an actor to the corresponding position or size of a source actor, * with or without an offset. * - #ClutterSnapConstraint, a constraint that "snaps" together the edges * of two #ClutterActors; if an actor uses two constraints on both its * horizontal or vertical edges then it can also expand to fit the empty * space. * * The [constraints example](https://git.gnome.org/browse/clutter/tree/examples/constraints.c?h=clutter-1.18) * uses various types of #ClutterConstraints to lay out three actors on a * resizable stage. Only the central actor has an explicit size, and no * actor has an explicit position. * * - The #ClutterActor with #ClutterActor:name `layerA` is explicitly * sized to 100 pixels by 25 pixels, and it's added to the #ClutterStage * - two #ClutterAlignConstraints are used to anchor `layerA` to the * center of the stage, by using 0.5 as the alignment #ClutterAlignConstraint:factor on * both the X and Y axis * - the #ClutterActor with #ClutterActor:name `layerB` is added to the * #ClutterStage with no explicit size * - the #ClutterActor:x and #ClutterActor:width of `layerB` are bound * to the same properties of `layerA` using two #ClutterBindConstraint * objects, thus keeping `layerB` aligned to `layerA` * - the top edge of `layerB` is snapped together with the bottom edge * of `layerA`; the bottom edge of `layerB` is also snapped together with * the bottom edge of the #ClutterStage; an offset is given to the two * #ClutterSnapConstraintss to allow for some padding; since `layerB` is * snapped between two different #ClutterActors, its height is stretched * to match the gap * - the #ClutterActor with #ClutterActor:name `layerC` mirrors `layerB`, * snapping the top edge of the #ClutterStage to the top edge of `layerC` * and the top edge of `layerA` to the bottom edge of `layerC` * * You can try resizing interactively the #ClutterStage and verify * that the three #ClutterActors maintain the same position and * size relative to each other, and to the #ClutterStage. * * It is important to note that Clutter does not avoid loops or * competing constraints; if two or more #ClutterConstraints * are operating on the same positional or dimensional attributes of an * actor, or if the constraints on two different actors depend on each * other, then the behavior is undefined. * * ## Implementing a ClutterConstraint * * Creating a sub-class of #ClutterConstraint requires the * implementation of the #ClutterConstraintClass.update_allocation() * virtual function. * * The `update_allocation()` virtual function is called during the * allocation sequence of a #ClutterActor, and allows any #ClutterConstraint * attached to that actor to modify the allocation before it is passed to * the actor's #ClutterActorClass.allocate() implementation. * * The #ClutterActorBox passed to the `update_allocation()` implementation * contains the original allocation of the #ClutterActor, plus the eventual * modifications applied by the other #ClutterConstraints, in the same order * the constraints have been applied to the actor. * * It is not necessary for a #ClutterConstraint sub-class to chain * up to the parent's implementation. * * If a #ClutterConstraint is parametrized - i.e. if it contains * properties that affect the way the constraint is implemented - it should * call clutter_actor_queue_relayout() on the actor to which it is attached * to whenever any parameter is changed. The actor to which it is attached * can be recovered at any point using clutter_actor_meta_get_actor(). */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include <string.h> #include "clutter-constraint-private.h" #include "clutter-actor.h" #include "clutter-actor-meta-private.h" #include "clutter-private.h" G_DEFINE_ABSTRACT_TYPE (ClutterConstraint, clutter_constraint, CLUTTER_TYPE_ACTOR_META); static void constraint_update_allocation (ClutterConstraint *constraint, ClutterActor *actor, ClutterActorBox *allocation) { } static void constraint_update_preferred_size (ClutterConstraint *constraint, ClutterActor *actor, ClutterOrientation direction, float for_size, float *minimum_size, float *natural_size) { } static void clutter_constraint_notify (GObject *gobject, GParamSpec *pspec) { if (strcmp (pspec->name, "enabled") == 0) { ClutterActorMeta *meta = CLUTTER_ACTOR_META (gobject); ClutterActor *actor = clutter_actor_meta_get_actor (meta); if (actor != NULL) clutter_actor_queue_relayout (actor); } if (G_OBJECT_CLASS (clutter_constraint_parent_class)->notify != NULL) G_OBJECT_CLASS (clutter_constraint_parent_class)->notify (gobject, pspec); } static void clutter_constraint_class_init (ClutterConstraintClass *klass) { GObjectClass *gobject_class = G_OBJECT_CLASS (klass); gobject_class->notify = clutter_constraint_notify; klass->update_allocation = constraint_update_allocation; klass->update_preferred_size = constraint_update_preferred_size; } static void clutter_constraint_init (ClutterConstraint *self) { } /*< private > * clutter_constraint_update_allocation: * @constraint: a #ClutterConstraint * @actor: a #ClutterActor * @allocation: (inout): the allocation to modify * * Asks the @constraint to update the @allocation of a #ClutterActor. * * Returns: %TRUE if the allocation was updated */ gboolean clutter_constraint_update_allocation (ClutterConstraint *constraint, ClutterActor *actor, ClutterActorBox *allocation) { ClutterActorBox old_alloc; g_return_val_if_fail (CLUTTER_IS_CONSTRAINT (constraint), FALSE); g_return_val_if_fail (CLUTTER_IS_ACTOR (actor), FALSE); g_return_val_if_fail (allocation != NULL, FALSE); old_alloc = *allocation; CLUTTER_CONSTRAINT_GET_CLASS (constraint)->update_allocation (constraint, actor, allocation); return !clutter_actor_box_equal (allocation, &old_alloc); } void clutter_constraint_update_preferred_size (ClutterConstraint *constraint, ClutterActor *actor, ClutterOrientation direction, float for_size, float *minimum_size, float *natural_size) { g_return_if_fail (CLUTTER_IS_CONSTRAINT (constraint)); g_return_if_fail (CLUTTER_IS_ACTOR (actor)); CLUTTER_CONSTRAINT_GET_CLASS (constraint)->update_preferred_size (constraint, actor, direction, for_size, minimum_size, natural_size); } ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/clutter/clutter/clutter-shader-effect.h������������������������������������������������0000664�0001750�0001750�00000011000�14211404421�022621� 0����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������/* * Clutter. * * An OpenGL based 'interactive canvas' library. * * Copyright (C) 2010 Intel Corporation. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

the layout will try * to maintain all its children on a single row or * column; * - if either the width or the height allocated are * smaller than the preferred ones, the layout will wrap; in this case, * the preferred height or width, respectively, will take into account * the amount of columns and rows; * - each line (either column or row) in reflowing will * have the size of the biggest cell on that line; if the * #ClutterFlowLayout:homogeneous property is set to %FALSE the actor * will be allocated within that area, and if set to %TRUE instead the * actor will be given exactly that area; * - the size of the columns or rows can be controlled * for both minimum and maximum; the spacing can also be controlled * in both columns and rows. * * The [flow-layout example](https://git.gnome.org/browse/clutter/tree/examples/flow-layout.c?h=clutter-1.18) * shows how to use the #ClutterFlowLayout. * * #ClutterFlowLayout is available since Clutter 1.2 */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include <math.h> #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "deprecated/clutter-container.h" #include "clutter-actor.h" #include "clutter-animatable.h" #include "clutter-child-meta.h" #include "clutter-debug.h" #include "clutter-enum-types.h" #include "clutter-flow-layout.h" #include "clutter-layout-meta.h" #include "clutter-private.h" struct _ClutterFlowLayoutPrivate { ClutterContainer *container;

If you need to schedule a closure * after an interval, see clutter_threads_add_timeout() instead. * * Users of #ClutterTimeline should connect to the #ClutterTimeline::new-frame * signal, which is emitted each time a timeline is advanced during the maste * clock iteration. The #ClutterTimeline::new-frame signal provides the time * elapsed since the beginning of the timeline, in milliseconds. A normalized * progress value can be obtained by calling clutter_timeline_get_progress(). * By using clutter_timeline_get_delta() it is possible to obtain the wallclock * time elapsed since the last emission of the #ClutterTimeline::new-frame * signal. * * Initial state can be set up by using the #ClutterTimeline::started signal, * while final state can be set up by using the #ClutterTimeline::stopped * signal. The #ClutterTimeline guarantees the emission of at least a single * #ClutterTimeline::new-frame signal, as well as the emission of the * #ClutterTimeline::completed signal every time the #ClutterTimeline reaches * its #ClutterTimeline:duration. * * It is possible to connect to specific points in the timeline progress by * adding markers using clutter_timeline_add_marker_at_time() and connecting * to the #ClutterTimeline::marker-reached signal. * * Timelines can be made to loop once they reach the end of their duration, by * using clutter_timeline_set_repeat_count(); a looping timeline will still * emit the #ClutterTimeline::completed signal once it reaches the end of its * duration at each repeat. If you want to be notified of the end of the last * repeat, use the #ClutterTimeline::stopped signal. * * Timelines have a #ClutterTimeline:direction: the default direction is * %CLUTTER_TIMELINE_FORWARD, and goes from 0 to the duration; it is possible * to change the direction to %CLUTTER_TIMELINE_BACKWARD, and have the timeline * go from the duration to 0. The direction can be automatically reversed * when reaching completion by using the #ClutterTimeline:auto-reverse property. * * Timelines are used in the Clutter animation framework by classes like * #ClutterAnimation, #ClutterAnimator, and #ClutterState. * * ## Defining Timelines in ClutterScript * * A #ClutterTimeline can be described in #ClutterScript like any * other object.

A * layout manager implements the layouting policy for a composite or a * container actor: it controls the preferred size of the actor to which * it has been paired, and it controls the allocation of its children. * * Any composite or container #ClutterActor subclass can delegate the * layouting of its children to a #ClutterLayoutManager. Clutter provides * a generic container using #ClutterLayoutManager called #ClutterBox. * * Clutter provides some simple #ClutterLayoutManager sub-classes, like * #ClutterFlowLayout and #ClutterBinLayout. * * ## Implementing a ClutterLayoutManager * The implementation of a layout manager does not differ from the * implementation of the size requisition and allocation bits of * #ClutterActor, so you should read the relative documentation * forr subclassing #ClutterActor. * * The layout manager implementation can hold a back pointer to the * #ClutterContainer by implementing the #ClutterLayoutManagerClass.set_container() * virtual function. The layout manager should not hold a real reference (i.e. * call g_object_ref()) on the container actor, to avoid reference cycles. * * If a layout manager has properties affecting the layout policies then it should * emit the #ClutterLayoutManager::layout-changed signal on itself by using the * clutter_layout_manager_layout_changed() function whenever one of these properties * changes. * * ## Layout Properties * * If a layout manager has layout properties, that is properties that * should exist only as the result of the presence of a specific (layout * manager, container actor, child actor) combination, and it wishes to store * those properties inside a #ClutterLayoutMeta, then it should override the * #ClutterLayoutManagerClass.get_child_meta_type() virtual function to return * the #GType of the #ClutterLayoutMeta sub-class used to store the layout * properties; optionally, the #ClutterLayoutManager sub-class might also * override the #ClutterLayoutManagerClass.create_child_meta() virtual function * to control how the #ClutterLayoutMeta instance is created, otherwise the * default implementation will be equivalent to: * * |[ * ClutterLayoutManagerClass *klass; * GType meta_type; * * klass = CLUTTER_LAYOUT_MANAGER_GET_CLASS (manager); * meta_type = klass->get_child_meta_type (manager); * * return g_object_new (meta_type, * "manager", manager, * "container", container, * "actor", actor, * NULL); * ]| * * Where `manager` is the #ClutterLayoutManager, `container` is the * #ClutterContainer using the #ClutterLayoutManager, and `actor` is * the #ClutterActor child of the #ClutterContainer. * * ## Using ClutterLayoutManager with ClutterScript * * #ClutterLayoutManager instances can be created in the same way * as other objects in #ClutterScript; properties can be set using the * common syntax. * * Layout properties can be set on children of a container with * a #ClutterLayoutManager using the `layout::` modifier on the property * name, for instance: * * |[ * { * "type" : "ClutterBox", * "layout-manager" : { "type" : "ClutterTableLayout" }, * "children" : [ * { * "type" : "ClutterTexture", * "filename" : "image-00.png", * * "layout::row" : 0, * "layout::column" : 0, * "layout::x-align" : "left", * "layout::y-align" : "center", * "layout::x-expand" : true, * "layout::y-expand" : true * }, * { * "type" : "ClutterTexture", * "filename" : "image-01.png", * * "layout::row" : 0, * "layout::column" : 1, * "layout::x-align" : "right", * "layout::y-align" : "center", * "layout::x-expand" : true, * "layout::y-expand" : true * } * ] * } * ]| * * #ClutterLayoutManager is available since Clutter 1.2 */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include <glib-object.h> #include <gobject/gvaluecollector.h> #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "deprecated/clutter-container.h" #include "deprecated/clutter-alpha.h" #include "clutter-debug.h" #include "clutter-layout-manager.h" #include "clutter-layout-meta.h" #include "clutter-marshal.h" #include "clutter-private.h" #include "clutter-timeline.h" #define LAYOUT_MANAGER_WARN_NOT_IMPLEMENTED(m,method) G_STMT_START { \ GObject *_obj = G_OBJECT (m);

This can be used in a * #ClutterBehaviourPath to animate an actor moving along the path. * * The path consists of a series of nodes. Each node is one of the * following four types: * * - %CLUTTER_PATH_MOVE_TO, changes the position of the path to the * given pair of coordinates. This is usually used as the first node * of a path to mark the start position. If it is used in the middle * of a path then the path will be disjoint and the actor will appear * to jump to the new position when animated. * - %CLUTTER_PATH_LINE_TO, creates a straight line from the previous * point to the given point. * - %CLUTTER_PATH_CURVE_TO, creates a bezier curve. The end of the * last node is used as the first control point and the three * subsequent coordinates given in the node as used as the other three. * -%CLUTTER_PATH_CLOSE, creates a straight line from the last node to * the last %CLUTTER_PATH_MOVE_TO node. This can be used to close a * path so that it will appear as a loop when animated. * * The first three types have the corresponding relative versions * %CLUTTER_PATH_REL_MOVE_TO, %CLUTTER_PATH_REL_LINE_TO and * %CLUTTER_PATH_REL_CURVE_TO.

It listens for low level events * such as #ClutterButtonEvent and #ClutterMotionEvent on the stage to raise * the #ClutterGestureAction::gesture-begin, #ClutterGestureAction::gesture-progress, * and #ClutterGestureAction::gesture-end signals. * * To use #ClutterGestureAction you just need to apply it to a #ClutterActor * using clutter_actor_add_action() and connect to the signals: * * |[<!-- language="C" --> * ClutterAction *action = clutter_gesture_action_new (); * * clutter_actor_add_action (actor, action); * * g_signal_connect (action, "gesture-begin", G_CALLBACK (on_gesture_begin), NULL); * g_signal_connect (action, "gesture-progress", G_CALLBACK (on_gesture_progress), NULL); * g_signal_connect (action, "gesture-end", G_CALLBACK (on_gesture_end), NULL); * ]| * * ## Creating Gesture actions * * A #ClutterGestureAction provides four separate states that can be * used to recognize or ignore gestures when writing a new action class: * * - Prepare -> Cancel * - Prepare -> Begin -> Cancel * - Prepare -> Begin -> End * - Prepare -> Begin -> Progress -> Cancel * - Prepare -> Begin -> Progress -> End * * Each #ClutterGestureAction starts in the "prepare" state, and calls * the #ClutterGestureActionClass.gesture_prepare() virtual function; this * state can be used to reset the internal state of a #ClutterGestureAction * subclass, but it can also immediately cancel a gesture without going * through the rest of the states. * * The "begin" state follows the "prepare" state, and calls the * #ClutterGestureActionClass.gesture_begin() virtual function. This state * signals the start of a gesture recognizing process. From the "begin" state * the gesture recognition process can successfully end, by going to the * "end" state; it can continue in the "progress" state, in case of a * continuous gesture; or it can be terminated, by moving to the "cancel" * state. * * In case of continuous gestures, the #ClutterGestureAction will use * the "progress" state, calling the #ClutterGestureActionClass.gesture_progress() * virtual function; the "progress" state will continue until the end of the * gesture, in which case the "end" state will be reached, or until the * gesture is cancelled, in which case the "cancel" gesture will be used * instead. * * Since: 1.8 */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include "clutter-gesture-action-private.h" #include "clutter-debug.h" #include "clutter-enum-types.h" #include "clutter-marshal.h" #include "clutter-private.h" #include <math.h> #define MAX_GESTURE_POINTS (10) #define FLOAT_EPSILON (1e-15) typedef struct { ClutterInputDevice *device;

This file is maintained # only for historical reasons. 2010-07-05 Alejandro Pieiro <apinheiro@igalia.com> Cleaning ClutterText * Removing superfluous g_return_if_fail * Removing unused ClutterText::text-changed callback 2010-07-05 Alejandro Pieiro <apinheiro@igalia.com> Refactoring "window:create" and "window:destroy" emission code Previously "window:create" and "window:destroy" were emitted on CallyUtil. Although it works, and CallyUtil already have callbacks to stage_added/removed signals, I think that it is more tidy/clear to do that on CallyRoot: * CallyRoot already has code to manage ClutterStage addition/removal * In fact, we can see CallyRoot as the object exposing the a11y information from ClutterStageManager, so it fits better here. * CallyUtil callbacks these signals are related to key event listeners (key snooper simulation). One of the main CallyUtil responsabilities is managing event (connecting, emitting), so I would prefer to not start to add/mix more functionalities here. Ideally it would be better to emit all CallyStage methods from CallyStage, but it is clear that "create" and "destroy" are more easy to emit from a external object. 2010-06-25 Alejandro Pieiro <apinheiro@igalia.com> Cleaning clutter-actor Some cleaning changes: * Using CallyActionFunc instead of ACTION_FUNC * Removing a extra * on cally-actor-private macro documentation, to avoid gtk-doc warnings * Using g_strcmp0 instead of strcmp Changes to be applied on clutter (see CB#2097 and CB#2098), applied also here to maintain the sync. My intention is keep this developing line until the real integration, in order to make a final independent cally release. 2010-06-14 Alejandro Pieiro <apinheiro@igalia.com> Adding -Wshadow option and solving warnings related 2010-06-14 Alejandro Pieiro <apinheiro@igalia.com> Added dummy padding for future vt expasion Added dummy padding on the different classes structures, to allow future expansion of virtual methods. I decided to add this on all the classes, although it would be really unlikely in some cases (ie, CallyGroup) 2010-06-10 Alejandro Pieiro <apinheiro@igalia.com> Adding and emitting "window:xxx" methods on CallyStage Added some window related signals on CallyStage: * window:activate and window:deactivate emitted from CallyStage * window:create and window:destroy emitted from CallyUtil ClutterStage doesn't fulfill 100% the window concept, but some of these signals are important in order to identify the object which could emit global/key events. The current implementation is equivalent to GailWindow one, supposing CallyStage as the only window related window. This likely would change in any clutter-based toolkit implement a real Window object, so a more flexible procedure would be required. But we would solve problems step by step. BTW: as I explain here [1] I really think that the current way to implement "window:xxx" signals (not defined in ATK but expected from the a11y implementation toolkit) somewhat hacky and undocumented (you need to check at-spi2 idls to know that you require to emit this events) Related to bug CB#2147 (Orca doesn't speech out properly non printable chars on some environments), as solves this problem in a specific case. [1] https://bugzilla.gnome.org/show_bug.cgi?id=620977#c1 2010-06-04 Alejandro Pieiro <apinheiro@igalia.com> Avoiding clutter_stage_get_key_focus warning For any reason, in some cases, a clutter actor doesn't have a stage associated. We use the default one as fallback. 2010-06-02 Alejandro Pieiro <apinheiro@igalia.com> Added a defunct check on cally_group_get_n_children Some warnings appeared when we tried to get the number of children of a defunct object. 2010-06-02 Alejandro Pieiro <apinheiro@igalia.com> Update TODO file Use Bugzilla to setting missing features. 2010-06-01 Alejandro Pieiro <apinheiro@igalia.com> Removing heuristics to decide CallyRectable/CallyTexture role Previously CallyRectangle and CallyTexture used some heuristics in order to decide the default role: ATK_ROLE_IMAGE or ATK_PUSH_BUTTON, as in practice most applications using these objects as buttons were not applying the proper role. As this is a hack, and a application responsibility, finally we have decided to remove this, so the default role is ATK_ROLE_IMAGE. Fixes CB#1732 (CallyTexture and CallyRectangle uses some heuristics to decide the role) 2010-05-28 Alejandro Pieiro <apinheiro@igalia.com> Post-release version bump, after release 1.2.0 I wrongly added the last commit on the 1.1 branch, when in fact it requires clutter 1.3.3, and on the README it is explained that cally versioning is tied to clutter versioning. In order to solve that a clutter-1.2 release branch is created, and bumped the version. This versioning tyding will be obsolete when the integration with clutter become a reality, but in the same way, this is the way to tidy this thinking in this integration. 2010-04-13 Alejandro Pieiro <apinheiro@igalia.com> Use clutter_actor_get_accessible The method clutter_actor_get_accessible was added due work on bug 2070, and should be used to get the accessibility object, instead of atk_gobject_accessible_for_object This would allow to implement a11y support directly on any clutter based toolkit object (ie StLabel). 2010-05-13 Alejandro Pieiro <apinheiro@igalia.com> Added CallyClone example 2010-05-13 Alejandro Pieiro <apinheiro@igalia.com> Added a11y support for ClutterClone Resolved in the most simplified way, just as a image and a default description to identify cloned objects. More information: http://lists.o-hand.com/clutter/3797.html 2010-04-14 Alejandro Pieiro <apinheiro@igalia.com> Remove gail dependency Removed to avoid gdk/gtk dependency on cally. Part of bug CB#2072 solution 2010-04-14 Alejandro Pieiro <apinheiro@igalia.com> Avoid gdk functions filling AtkKeyEventStruct Now when AtkKeyEventStruct is filled in order to emit any key event signal, it is not used any gdk function on the keyval or the string fields. event_string is filled with the printable character if possible, if not (Ctrl, Alt, etc) it is set as NULL. Now the AT should take care of that, at least until we define atk key event struct in a more agnostic way (not tied to gdk/gtk). See orca bug bgo#616206 as a example. Part of bug CB#2072 solution. 2010-04-15 Alejandro Pieiro <apinheiro@igalia.com> Added gail_misc_layout_get_run_attributes implementation Part of bug CB#2072 solution 2010-04-14 Alejandro Pieiro <apinheiro@igalia.com> Remove gailutil/gailmisc functions calls This is because gailutil/gailmisc added a gdk/gtk dependency, and this dependency is being removed. New cally-specific implementation are required. Related to bug CB#1733 Part of bug CB#2072 solution 2010-04-13 Alejandro Pieiro <apinheiro@igalia.com> Fixing the libdir directory in some examples 2010-03-26 Alejandro Pieiro <apinheiro@igalia.com> Previous cally.pc.in update was incomplete The previous commit was not tested properly, and it was missing one detail. Sorry for the noise. 2010-03-26 Alejandro Pieiro <apinheiro@igalia.com> Update cally.pc.in after module relocation Previous commit places cally module in a different directory. It also corrects where the include directory is placed. 2010-03-15 Alejandro Pieiro <apinheiro@igalia.com> Use a proper clutter module directory Use a proper clutter module directory, instead of keep being installed on a gtk directory. Improve the cally-examples-util, in order to keep using hardcoded values. Fixes CB#1737 (Wrong cally module directory) 2010-03-15 Alejandro Pieiro <apinheiro@igalia.com> Proper UTF-8 headers 2010-02-25 Alejandro Pieiro <apinheiro@igalia.com> Change "--with-dbus" option for "atk-bridge-dir" on examples The atk-adaptor in the dbus at-spi was renamed to atk-bridge due some apps hardcoding the name. So right now the only difference is the final directory. So the option was removed, and atk-bridge-dir added. This also allows to use the system atk-bridge or the compiled in any developing environment, so it is really more flexible. See the README (updated with this commit) for more information. 2010-02-19 Alejandro Pieiro <apinheiro@igalia.com> Added .gitignore file 2010-02-19 Alejandro Pieiro <apinheiro@igalia.com> Release 1.1.1 2010-02-19 Alejandro Pieiro <apinheiro@igalia.com> Using clutter_threads_idle_add instead of the gdk one The idea is being as less gdk dependent as possible. Right now it is inviable to remove the dependency (gailutil and so on) but hypothetically, the ideal is remove this dependency in the future, and being "clutter pure". 2010-02-15 Alejandro Pieiro <apinheiro@igalia.com> Check if the state is defunct on cally_text_get_name Check if the state is defunct on cally_text_get_name, in order to avoid warnings cally clutter_text_get_text when the clutter object is NULL 2010-01-26 Alejandro Pieiro <apinheiro@igalia.com> Update on configure.ac after autoupdate call 2010-02-02 Alejandro Pieiro <apinheiro@igalia.com> Try to apply the key modifiers to event->keyval like GDK does ClutterKeyEvent defines the keyval without taking into account the modifiers. GDK defines this keyval taking into account the modifiers. AtkKeyEventStruct expects the keyval in a GDK fashion, so a translation is required. This patch tries to do that using using gdk_keymap_translate_keyboard_state. This functions only works correctly if gtk has been initialized, so the fallback is create the AtkKeyEventStruct with the keyval provided by Clutter. More information: http://library.gnome.org/devel/atk/stable/AtkUtil.html#AtkKeyEventStruct http://bugzilla.openedhand.com/show_bug.cgi?id=1961 2010-02-02 Alejandro Pieiro <apinheiro@igalia.com> Filling AtkKeyEventStruct->string used on the atk key event listeners Finally we use directly gdk_keyval_name. Not the ideal solution, but works, and more important, it avoids to reimplement this issue on clutter or cally. More information on Bug 1952 Fixes http://bugzilla.openedhand.com/show_bug.cgi?id=1952 2010-01-22 Alejandro Pieiro <apinheiro@igalia.com> Added AM_PROG_CC_C_O option to avoid a warning running configure 2010-01-22 Alejandro Pieiro <apinheiro@igalia.com> Fix clutter version required on the pc files 2010-01-22 Alejandro Pieiro <apinheiro@igalia.com> Check on configure time if any x11 clutter backend is in use It uses AC_CHECK_LIB in order to check if x11 backend is in use. It also modifies cally-actor in order to use the information retrieved. So now cally has a minimum multi-backend support. It only manages a x11 (glx or eglx) backend, but at least, it checks it, so you can compile cally without this backend. It probably will not work properly, but at least you can compile and execute it. Solves http://bugzilla.openedhand.com/show_bug.cgi?id=1736 2010-01-21 Alejandro Pieiro <apinheiro@igalia.com> Fix the perspective problems computing the on-screen extensions Use clutter_actor_get_abs_allocation_vertices and clutter_actor_get_transformed_size to get the real on-screen position and size, instead of compute that using the geometry and the anchor point. It also update cally-atkcomponent-example, adding a actor inside a nested ClutterGroup hierarchy. Fixes: http://bugzilla.openedhand.com/show_bug.cgi?id=1731 2010-01-13 Alejandro Pieiro <apinheiro@igalia.com> Added extra button on cally-atkeditabletext-example Added a button to print the current cursor position, and also extend the size of the buttons 2010-01-12 Alejandro Pieiro <apinheiro@igalia.com> Remove superfluous g_print on CallyStage 2009-12-03 Alejandro Pieiro <apinheiro@igalia.com> Use clutter_stage_manager_peek_stages to avoid a leak 2009-12-03 Alejandro Pieiro <apinheiro@igalia.com> Added ATK_STATE_SELECTABLE_TEXT management 2009-11-26 Alejandro Pieiro <apinheiro@igalia.com> Manage properly ATK_STATE_ACTIVE on CallyStage * cally/cally-stage.c Added private struct (cally_stage_class_init),(cally_stage_init),(cally_stage_real_initalize): Initialization stuff (cally_stage_activate_cb) (cally_stage_deactivate_cb): new ClutterStage signal callbacks, change the internal value of active, and notify the atk state change (cally_stage_ref_state_set): manage ATK_STATE_ACTIVATE * examples/cally-atktext-example2.c If possible, creates two stage, in order to test ATK_STATE_ACTIVATE 2009-11-24 Alejandro Pieiro <apinheiro@igalia.com> Focused state change and focused object notification * cally/cally-actor.h (focus_clutter): added virtual method for the focus management * cally/cally-actor.c (cally_actor_component_interface_init) (cally_actor_add_focus_handler) (cally_actor_remove_focus_handler): Implementation of the AtkComponent methods add_focus_handler and remove_focus_handler (cally_actor_focus_event): CallyActor specific focus handler, notify the state focused change (cally_actor_focus_clutter) (cally_actor_real_focus_clutter): Handlers for the ClutterActor "key-focus-in" and "key-focus-out" signals. Emit the signal AtkObject "focus_event" and set the focus object with atk_focus_tracker_notify. (cally_actor_initialize): Connect to the signals "key-focus-in" and "key-focus-out", use atk_component_add_focus_handler to add cally_actor_focus_event Note: The focus management is more simplified that the gail one. The main reason is that the focus management in GTK is really more complex that the Clutter one. 2009-11-24 Alejandro Pieiro <apinheiro@igalia.com> Modify cally-atkeditabletext-example.c to manage "activatable" status 2009-11-24 Alejandro Pieiro <apinheiro@igalia.com> Added "activate" action in ClutterText * cally/cally-actor.h * cally/cally-actor.c cally_actor_add_action now returns the action id added. Documentation added in order to explain the return values and others. * cally/cally-text.c Added action "activate". This action is only available if the ClutterText is activatable, so the "activatable" property is tracked in the notify 2009-11-20 Alejandro Pieiro <apinheiro@igalia.com> Signal event emission Emits the signals "text_selection_changed", "text_caret_moved", "text_changed::insert", "text_changed::delete", and notify the ATK_STATE_EDITABLE state change. It also adds the ATK_STATE_EDITABLE in the ref_state_set, includes a finalize to clean the new private data used, and move part of the initialization from the _init to the _real_initialization. 2009-12-03 Alejandro Pieiro <apinheiro@igalia.com> Remove the ATK_STATE_DEFUNCT emission Remove the ATK_STATE_DEFUNCT emission, as this is already made by AtkGObjectAccessible. It also removes the clutter actor from the private structure, as we can use the AtkGObjectAccessible API to obtain it. This makes the code more coherent, with respect of the rest of the Cally classes implementation. 2009-11-26 Alejandro Pieiro <apinheiro@igalia.com> Remove ; from the CALLY_GET_CLUTTER_ACTOR macro 2009-11-25 Alejandro Pieiro <apinheiro@igalia.com> TODO cleanup and more implementation notes * TODO: removed the data that we have in the bugzilla or in the implementation notes on the cally source * cally/cally-actor.c: complete implementations notes * cally/Makefile.am: add a comment related to the public headers, and include Makefile.in in the MAINTAINERCLEANFILES 2009-11-13 Alejandro Pieiro <apinheiro@igalia.com> Adding new tips on CODING_STYLE 2009-11-09 Alejandro Pieiro <apinheiro@igalia.com> AtkEditableText implementation on CallyText * examples/Makefile.am * examples/cally-atkeditabletext-example.c: New example added * cally/cally-text.c Interface AtkEditableText implemented, except some methods: * Missing ClipBoard feature on Clutter: paste_text copy_text cut_text * Missing a equivalent GtkTextTag on Clutter (so the possibility to set run attributes in a range): set_run_attributes Fixes bug CB#1734 2009-11-03 Alejandro Pieiro <apinheiro@igalia.com> Removed DG_DISABLE_CHECKS and DG_DISABLE_CAST_CHECKS from CFLAGS * configure.ac: Removed DG_DISABLE_CHECKS and DG_DISABLE_CAST_CHECKS from the common CFLAGS options * cally/cally-actor.c: fixed cast errors on some return values, not detected previously because of the use of relaxed compilation options Problem detected by Mario Sánchez Prada <msanchez@igalia.com> 2009-10-28 Alejandro Pieiro <apinheiro@igalia.com> Support for multiple stages * cally-root.c * cally-stage.c * cally-util.c Implemented the support for multiple stages, by tracking the signals stage-added and stage-removed of the ClutterStageManager. In the same way CallyRoot has implement properly the atk_object_initialize, and in general now is more tied to ClutterStageManager (CallyRoot is now the a11y object of ClutterStageManager), but factory not required anyway, as it is instanced on the CallyUtil atk_get_root Fixes: CB#1754 (Missing multi-stage support) 2009-10-27 Alejandro Pieiro <apinheiro@igalia.com> Implemented atk_[add/remove]_key_event_listener on CallyUtil * cally/cally-util.c: Implemented atk_[add/remove]_key_event_listener * examples/cally-atktext-example2.c: Modified in order to install and remove key event listeners, for testing purposes Fixes CB#1852 (AtkUtil implementation misses atk_[add/remove]_key_event_listener) 2009-10-21 Alejandro Pieiro <apinheiro@igalia.com> Implemented atk-[add/remove]-global-event-listener on CallyUtil * cally/cally-util.c: Implemented atk-[add/remove]-global-event-listener on CallyUtil * examples/Makefile.am * examples/cally-atktext-example2.c New example in order to test easier the event emission on focus change (not working right now) 2009-10-12 Alejandro Pieiro <apinheiro@igalia.com> Add --with-dbus option executing the examples The replacement for atk-bridge on at-spi-dbus has a different name (atk-adaptor), and it has not defined the method gnome_accessibility_init. The --with-dbus option allow to load the correct library and use the correct hook method if you are using at-spi-dbus. Anyway, take into account that this is just an example, and in a final environment, this should be made in a more general way. More information: CB#1738, CB#1737 2009-09-25 Alejandro Pieiro <apinheiro@igalia.com> Symplifying shave support. 2009-09-25 Alejandro Pieiro <apinheiro@igalia.com> Cleanup on the compilation and installation process * cally/Makefile.am: Added libcallydir and libcally_HEADERS in order to publish all cally headers, as the current policy is use the cally headers as public. * configure.ac: Change API_VERSION_MAJOR for CALLY_API_VERSION, as was the real meaning, and define CALLY_VERSION. Change CALLY_OBJ_CFLAGS and CALLY_OBJ_LIBS, used to compile the tests, as was not required to compile against the cally module (the example only required to compile against Clutter, as the cally module was just a module loaded by GModule). Support for Shave. 2009-07-31 Alejandro Pieiro <apinheiro@igalia.com> Be able to run the examples without installing Cally Before that, the examples searched the cally module from the final installed directory. This means that you should install the library to use the examples. On development this is not desirable. Now it is loaded from ../cally/.libs This is a little hackish, but more useful, and in the end, it is just a example. Probably a best option could be configure that on the command line. $ ./example --cally-dir="mydir" But just a nitpick. 2009-07-29 Alejandro Pieiro <apinheiro@igalia.com> Upgrade to cally-1.0, using clutter-1.0 * NEWS * TODO: removed several items, waiting to be moved to the bugzilla * configure.ac * examples/cally-examples-util.c 2009-07-27 Alejandro Pieiro <apinheiro@igalia.com> Fixed return value of cally_actor_get_index_in_parent Bug and solutiond pointed by Gerd Kohlberger 2009-06-30 Alejandro Pieiro <apinheiro@igalia.com> Added the implementation of most AtkText methods for CluttetText (CallyText) It remains some methods: get_default_attributes get_character_extents get_offset_at_point The current gail implementation delegate on gailmisc, but this is tied to GtkWidget so an equivalent functionality would be implemented (something like callymisc), and in the case of get_character_extents, not sure about the layout position (see gtk_entry_get_layout_offsets). I think that worth manage this in a different commit. In the same way is still missing AtkEditableText support. 2009-07-07 Alejandro Pieiro <apinheiro@igalia.com> Added CALLY_GET_CLUTTER_ACTOR macro This macro was created to simplify how do you get the clutter actor object related to the cally object. On CallyActor a private attributte maintains it (for convenience, as it is heavily used) but outside, atkgobject methods can be used. Note that there is a possibility on the future to change it. Two options: * Add a public method to get the clutter object * Use this method on CallyActor too This macro simplifies this: CLUTTER_ACTOR (atk_gobject_accessible_get_object (ATK_GOBJECT_ACCESSIBLE (cally_object))) 2009-06-24 Alejandro Pieiro <apinheiro@igalia.com> Renamed examples/cally-util.[ch] to examples/cally-examples-util.[ch] Renamed examples/cally-util.[ch] to examples/cally-examples-util.[ch] to avoid confusion with cally/cally-util.[ch], implementation of the AtkUtil interface 2009-06-23 Alejandro Pieiro <apinheiro@igalia.com> Adding examples directory * NEWS: Updates * configure.ac * Makefile.am * cally/Makefile.am * examples/Makefile.am: New * examples/cally-util.[ch]: New * examples/example1.c: New Added a directory in order to put examples. In this way we don't require any external clutter app to make the basic a11y functionality checks. At this moment only an example was added, but all the compiling structure is working. By default the examples are not compiled, use "--enable-examples" on configure time in order to enable their compilation. This basic example basically shows several objects, with different depth, in order to check that AtkComponent returns the correct screen position. Other minor changes done on the building infrastructure. 2009-06-23 Alejandro Pieiro <apinheiro@igalia.com> Fix clutter version required 2009-06-23 Alejandro Pieiro <apinheiro@igalia.com> Solve a

Basically any actor can be focused using * clutter_stage_set_key_focus. So, we will use this approach: all actors are * focusable, and we get the currently focused using clutter_stage_get_key_focus * This affects focus related stateset and some atk_componenet focus methods (like * grab focus). * * In the same way, we will manage the focus state change management * on the cally-stage object. The reason is avoid missing a focus * state change event if the object is focused just before the * accessibility object being created. * * #AtkAction implementation: on previous releases ClutterActor added * the actions "press", "release" and "click", as at that time some * general-purpose actors like textures were directly used as buttons. * * But now, new toolkits appeared, providing high-level widgets, like * buttons. So in this environment, it doesn't make sense to keep * adding them as default. * * Anyway, current implementation of AtkAction is done at CallyActor * providing methods to add and remove actions.

So, from a a11y POV * CallyCloneTexture was just another image, like ClutterTexture, and if * it was a clone was irrevelant. So on cally-0.8, CallyCloneTexture * expose a object with role ATK_ROLE_IMAGE. But now, ClutterClone is more * general. You can clone any object, including groups, and made things * like have one text entry, and a clone with different properties in the * same window, updated both at once. * * The question is if the idea is have a ClutterClone as a "first-class" * citizen inside the stage hierarchy (full clone), or it is just supposed * to be a mirror image of the original object. * * In the case of the a11y POV this would mean that if the text changes on * the source, the clone should emit as well the text-changing signals. * * As ClutterClone smartly just paint the same object with different * parameters, this would mean that it should be the cally object the one * that should replicate the source clutter hierarchy to do that, * something that just sound crazy. * * Taking into account that: * * - ClutterClone doesn't re-emit mirrored signals from the source * I think that likely the answer would be "yes, it is just a * mirrored image, not a real full clone". * * - You can't interact directly with the clone (ie: focus, and so on). * Its basic usage (right now) is clone textures. * * Any other solution could be overwhelming. * * I think that the final solution would be that ClutterClone from the * a11y POV should still be managed as a image (with the proper properties, * position, size, etc.). */ #include "clutter-build-config.h" #include "cally-clone.h" #include "cally-actor-private.h" /* AtkObject */ static void cally_clone_real_initialize (AtkObject *obj, gpointer data); G_DEFINE_TYPE (CallyClone, cally_clone, CALLY_TYPE_ACTOR) static void cally_clone_class_init (CallyCloneClass *klass) { /* GObjectClass *gobject_class = G_OBJECT_CLASS (klass); */ AtkObjectClass *class = ATK_OBJECT_CLASS (klass); class->initialize = cally_clone_real_initialize; } static void cally_clone_init (CallyClone *clone) { /* nothing to do yet */ } /** * cally_clone_new: * @actor: a #ClutterActor * * Creates a new #CallyClone for the given @actor. @actor must be a * #ClutterClone. * * Return value: the newly created #AtkObject * * Since: 1.4 */ AtkObject* cally_clone_new (ClutterActor *actor) { GObject *object = NULL; AtkObject *accessible = NULL; g_return_val_if_fail (CLUTTER_IS_CLONE (actor), NULL); object = g_object_new (CALLY_TYPE_CLONE, NULL); accessible = ATK_OBJECT (object); atk_object_initialize (accessible, actor); return accessible; } static void cally_clone_real_initialize (AtkObject *obj, gpointer data) { ATK_OBJECT_CLASS (cally_clone_parent_class)->initialize (obj, data); obj->role = ATK_ROLE_IMAGE; } ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������muffin-5.2.1/clutter/clutter/cally/cally-text.h�����������������������������������������������������0000664�0001750�0001750�00000005021�14211404421�021641� 0����������������������������������������������������������������������������������������������������ustar �jpeisach������������������������jpeisach���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������/* CALLY - The Clutter Accessibility Implementation Library * * Copyright (C) 2009 Igalia, S.L. * * Author: Alejandro Piñeiro Iglesias <apinheiro@igalia.com> * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It is also convenient * to implement the #ClutterShaderEffectClass.get_static_shader_source() * virtual function in case you are planning to create more than one * instance of the effect. * * The #ClutterShaderEffectClass.get_static_shader_source() * function should return a copy of the shader source to use. This * function is only called once per subclass of #ClutterShaderEffect * regardless of how many instances of the effect are created. The * source for the shader is typically stored in a static const * string which is returned from this function via * g_strdup(). * * The #ClutterOffscreenEffectClass.paint_target() should set the * shader's uniforms if any. This is done by calling * clutter_shader_effect_set_uniform_value() or * clutter_shader_effect_set_uniform(). The sub-class should then * chain up to the #ClutterShaderEffect implementation. * * ## Setting uniforms on a ClutterShaderEffect * * The example below shows a typical implementation of the * #ClutterShaderEffectClass.get_static_shader_source() and * #ClutterOffscreenEffectClass.paint_target() virtual functions * for a #ClutterShaderEffect subclass. * * |[<!-- language="C" --> * static gchar * * my_effect_get_static_shader_source (ClutterShaderEffect *effect) * { * // shader_source is set elsewhere * return g_strdup (shader_source); * } * * static gboolean * my_effect_paint_target (ClutterOffscreenEffect *effect) * { * MyEffect *self = MY_EFFECT (effect); * ClutterShaderEffect *shader = CLUTTER_SHADER_EFFECT (effect); * ClutterEffectClass *parent_class; * gfloat component_r, component_g, component_b; * * // the "tex" uniform is declared in the shader as: * // * // uniform int tex; * // * // and it is passed a constant value of 0 * clutter_shader_effect_set_uniform (shader, "tex", G_TYPE_INT, 1, 0); * * // the "component" uniform is declared in the shader as: * // * // uniform vec3 component; * // * // and it's defined to contain the normalized components * // of a #ClutterColor * component_r = self->color.red / 255.0f; * component_g = self->color.green / 255.0f; * component_b = self->color.blue / 255.0f; * clutter_shader_effect_set_uniform (shader, "component", * G_TYPE_FLOAT, 3, * component_r, * component_g, * component_b); * * // chain up to the parent's implementation * parent_class = CLUTTER_OFFSCREEN_EFFECT_CLASS (my_effect_parent_class); * return parent_class->paint_target (effect); * } * ]| */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include "cogl/cogl.h" #include "clutter-shader-effect.h" #include "clutter-debug.h" #include "clutter-enum-types.h" #include "clutter-feature.h" #include "clutter-private.h" #include "clutter-shader-types.h" typedef struct _ShaderUniform { gchar *name; GType type; GValue value; int location; } ShaderUniform; struct _ClutterShaderEffectPrivate { ClutterActor *actor; ClutterShaderType shader_type; CoglHandle program; CoglHandle shader; GHashTable *uniforms; }; typedef struct _ClutterShaderEffectClassPrivate { /* These are the per-class pre-compiled shader and program which is used when the class implements get_static_shader_source without calling set_shader_source.

You should use * the [implicit animation API][clutter-actor-animation] available inside * #ClutterActor instead. If you require to define explicit transitions for * one or more properties in order to reuse them, see #ClutterTransition * instead. * * ## Defining ClutterAnimationMode inside ClutterScript * * When defining a #ClutterAnimation inside a ClutterScript * file or string the #ClutterAnimation:mode can be defined either * using the #ClutterAnimationMode enumeration values through their * "nick" (the short string used inside #GEnumValue), their numeric * id, or using the following strings: * * - easeInQuad, easeOutQuad, easeInOutQuad * - easeInCubic, easeOutCubic, easeInOutCubic * - easeInQuart, easeOutQuart, easeInOutQuart * - easeInQuint, easeOutQuint, easeInOutQuint * - easeInSine, easeOutSine, easeInOutSine * - easeInExpo, easeOutExpo, easeInOutExpo * - easeInCirc, easeOutCirc, easeInOutCirc * - easeInElastic, easeOutElastic, easeInOutElastic * - easeInBack, easeOutBack, easeInOutBack * - easeInBounce, easeOutBounce, easeInOutBounce */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include #include #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "clutter-alpha.h" #include "clutter-animatable.h" #include "clutter-animation.h" #include "clutter-debug.h" #include "clutter-enum-types.h" #include "clutter-interval.h" #include "clutter-marshal.h" #include "clutter-private.h" #include "clutter-scriptable.h" #include "clutter-script-private.h" #include "deprecated/clutter-animation.h" enum { PROP_0, PROP_OBJECT, PROP_MODE, PROP_DURATION, PROP_LOOP, PROP_TIMELINE, PROP_ALPHA, PROP_LAST }; static GParamSpec *obj_props[PROP_LAST]; enum { STARTED, COMPLETED, LAST_SIGNAL }; struct _ClutterAnimationPrivate { GObject *object; GHashTable *properties; ClutterAlpha *alpha; ClutterTimeline *timeline; guint timeline_started_id; guint timeline_completed_id; guint timeline_frame_id; }; static guint animation_signals[LAST_SIGNAL] = { 0, }; static GQuark quark_object_animation = 0; static void clutter_scriptable_init (ClutterScriptableIface *iface); static void clutter_animation_set_alpha_internal (ClutterAnimation *animation, ClutterAlpha *alpha); static ClutterAlpha * clutter_animation_get_alpha_internal (ClutterAnimation *animation); static ClutterTimeline * clutter_animation_get_timeline_internal (ClutterAnimation *animation); G_DEFINE_TYPE_WITH_CODE (ClutterAnimation, clutter_animation, G_TYPE_OBJECT, G_ADD_PRIVATE (ClutterAnimation) G_IMPLEMENT_INTERFACE (CLUTTER_TYPE_SCRIPTABLE, clutter_scriptable_init)); static ClutterAlpha * clutter_animation_get_alpha_internal (ClutterAnimation *animation) { ClutterAnimationPrivate *priv = animation->priv; if (priv->alpha == NULL) { ClutterAlpha *alpha; alpha = clutter_alpha_new (); clutter_alpha_set_mode (alpha, CLUTTER_LINEAR); priv->alpha = g_object_ref_sink (alpha); g_object_notify_by_pspec (G_OBJECT (animation), obj_props[PROP_ALPHA]); } return priv->alpha; } static void on_actor_destroy (ClutterActor *actor, ClutterAnimation *animation) { ClutterAnimationPrivate *priv = animation->priv; GObject *obj = G_OBJECT (actor); if (obj == priv->object) { g_object_set_qdata (priv->object, quark_object_animation, NULL); g_signal_handlers_disconnect_by_func (priv->object, G_CALLBACK (on_actor_destroy), animation); g_object_unref (animation); } } static void clutter_animation_real_completed (ClutterAnimation *self) { ClutterAnimationPrivate *priv = self->priv; ClutterAnimatable *animatable = NULL; ClutterAnimation *animation; ClutterTimeline *timeline; ClutterTimelineDirection direction; gpointer key, value; GHashTableIter iter; timeline = clutter_animation_get_timeline (self); direction = clutter_timeline_get_direction (timeline); if (CLUTTER_IS_ANIMATABLE (priv->object)) animatable = CLUTTER_ANIMATABLE (priv->object); /* explicitly set the final state of the animation */ CLUTTER_NOTE (ANIMATION, "Set final state on object [%p]", priv->object); g_hash_table_iter_init (&iter, priv->properties); while (g_hash_table_iter_next (&iter, &key, &value)) { const gchar *p_name = key; ClutterInterval *interval = value; GValue *p_value; if (direction == CLUTTER_TIMELINE_FORWARD) p_value = clutter_interval_peek_final_value (interval); else p_value = clutter_interval_peek_initial_value (interval); if (animatable != NULL) clutter_animatable_set_final_state (animatable, p_name, p_value); else g_object_set_property (priv->object, p_name, p_value); } /* at this point, if this animation was created by clutter_actor_animate() * and friends, the animation will be attached to the object's data; since * we want to allow developers to use g_signal_connect_after("completed") * to concatenate a new animation, we need to remove the animation back * pointer here, and unref() the animation.

If the source_state_name for a key * is NULL it is used for transition to the target state unless a specific key * exists for transitioning from the current state to the requested state. * * #ClutterState is available since Clutter 1.4. * * #ClutterState has been deprecated in Clutter 1.12. There is no direct * replacement for this API, but it's highly suggested you use a combination * of [implicit transitions][clutter-actor-animation] and explicit transitions * using #ClutterTransition and its subclasses. * * ## Using ClutterState * * The following example defines a "base" and a "hover" state in a * #ClutterState instance. * * |[ * ClutterState *state = clutter_state_new (); * ClutterColor color = { 0, }; * * // transition from any state to the "base" state * clutter_color_from_string (&color, "rgb(255, 0, 0)"); * clutter_state_set (state, NULL, "base", * actor, "color", CLUTTER_LINEAR, &color, * actor, "scale-x", CLUTTER_EASE_IN_BOUNCE, 1.0, * actor, "scale-y", CLUTTER_EASE_IN_BOUNCE, 1.0, * NULL); * * // transition from the "base" state to the "hover" state * clutter_color_from_string (&color, "rgb(0, 0, 255)"); * clutter_state_set (state, "base", "hover", * actor, "color", CLUTTER_LINEAR, &color, * actor, "scale-x", CLUTTER_EASE_OUT_BOUNCE, 1.7, * actor, "scale-y", CLUTTER_EASE_OUT_BOUNCE, 1.7, * NULL); * * // the default duration of any transition * clutter_state_set_duration (state, NULL, NULL, 500); * * // set "base" as the initial state * clutter_state_warp_to_state (state, "base"); * ]| * * The actor then uses the #ClutterState to animate through the * two states using callbacks for the #ClutterActor::enter-event and * #ClutterActor::leave-event signals. * * |[ * static gboolean * on_enter (ClutterActor *actor, * ClutterEvent *event, * ClutterState *state) * { * clutter_state_set_state (state, "hover"); * * return CLUTTER_EVENT_STOP; * } * * static gboolean * on_leave (ClutterActor *actor, * ClutterEvent *event, * ClutterState *state) * { * clutter_state_set_state (state, "base"); * * return CLUTTER_EVENT_STOP; * } * * ## ClutterState description for ClutterScript * * #ClutterState defines a custom `transitions` JSON object member which * allows describing the states. * * The `transitions` property has the following syntax: * * |[ * { * "transitions" : [ * { * "source" : "source-state", * "target" : "target-state", * "duration" : milliseconds, * "keys" : [ * [ * "object-id", * "property-name", * "easing-mode", * "final-value", * ], * [ * "object-id", * "property-name", * "easing-mode", * "final-value", * pre-delay, * post-delay; * ], * ... * ] * }, * { * "source" : "source-state", * "target" : "target-state", * "duration" : milliseconds, * "animator" : "animator-definition" * }, * ... * ] * } * ]| * * Each element of the transitions array follows the same rules and order * as clutter_state_set_key() function arguments. * * The source and target values control the source and target state of the * transition. The key and animator properties are mutually exclusive. * * The pre-delay and post-delay values are optional. * * The example below is a translation into a #ClutterScript definition of * the code in the #ClutterState example above. * * |[ * { * "id" : "button-state", * "type" : "ClutterState", * "duration" : 500, * "transitions" : [ * { * "source" : "*", * "target" : "base", * "keys" : [ * [ "button", "color", "linear", "rgb(255, 0, 0)" ], * [ "button", "scale-x", "easeInBounce", 1.0 ], * [ "button", "scale-y", "easeInBounce", 1.0 ] * ] * }, * { * "source" : "base", * "target" : "hover", * "keys" : [ * [ "button", "color", "linear", "rgb(0, 0, 255)" ], * [ "button", "scale-x", "easeOutBounce", 1.7 ], * [ "button", "scale-y", "easeOutBounce", 1.7 ] * ] * } * ] * } * ]| */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include #include #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "clutter-state.h" #include "clutter-alpha.h" #include "clutter-animatable.h" #include "clutter-animator.h" #include "clutter-enum-types.h" #include "clutter-interval.h" #include "clutter-marshal.h" #include "clutter-private.h" #include "clutter-scriptable.h" #include "clutter-script-private.h" typedef struct StateAnimator { const gchar *source_state_name; /* interned string identifying entry */ ClutterAnimator *animator; /* pointer to animator itself */ } StateAnimator; typedef struct State { const gchar *name; /* interned string for this state name */ GHashTable *durations; /* durations for transitions from various state names */ GList *keys; /* list of all keys pertaining to transitions from other states to this one */ GArray *animators; /* list of animators for transitioning from * specific source states */ ClutterState *clutter_state; /* the ClutterState object this state belongs to */ } State; struct _ClutterStatePrivate { GHashTable *states; /* contains state objects */ guint duration; /* global fallback duration */ ClutterTimeline *timeline; /* The timeline used for doing the progress */ ClutterTimeline *slave_timeline; /* a slave timeline used to compute alphas */ const gchar *source_state_name; /* current source state */ State *source_state; /* current source_state */ const gchar *target_state_name; /* current target state */ State *target_state; /* target state name */ ClutterAnimator *current_animator; /* !NULL if the current transition is overriden by an animator */ }; #define SLAVE_TIMELINE_LENGTH 10000 /* * ClutterStateKey: * * An opaque data structure with accessor functions. * */ typedef struct _ClutterStateKey { GObject *object; /* an Gobject */ const gchar *property_name;/* the name of a property */ gulong mode; /* alpha to use */ GValue value; /* target value */ gdouble pre_delay; /* fraction of duration to delay before starting */ gdouble pre_pre_delay;/* fraction of duration to add to pre_delay.

The factor can * then be used to drive a #ClutterBehaviour, which will translate the * alpha value into something meaningful for a #ClutterActor. * * You should provide a #ClutterTimeline and bind it to the #ClutterAlpha * instance using clutter_alpha_set_timeline(). You should also set an * "animation mode", either by using the #ClutterAnimationMode values that * Clutter itself provides or by registering custom functions using * clutter_alpha_register_func(). * * Instead of a #ClutterAnimationMode you may provide a function returning * the alpha value depending on the progress of the timeline, using * clutter_alpha_set_func() or clutter_alpha_set_closure(). The alpha * function will be executed each time a new frame in the #ClutterTimeline * is reached. * * Since the alpha function is controlled by the timeline instance, you can * pause, stop or resume the #ClutterAlpha from calling the alpha function by * using the appropriate functions of the #ClutterTimeline object. * * #ClutterAlpha is used to "drive" a #ClutterBehaviour instance, and it * is internally used by the #ClutterAnimation API. * * #ClutterAlpha is available since Clutter 0.2. * * #ClutterAlpha is deprecated since Clutter 1.12. #ClutterTimeline and * the #ClutterTimeline:progress-mode property replace this whole class. * * ## ClutterAlpha custom properties for #ClutterScript * * #ClutterAlpha defines a custom `function` property for * #ClutterScript which allows to reference a custom alpha function * available in the source code. Setting the `function` property * is equivalent to calling clutter_alpha_set_func() with the * specified function name. No user data or #GDestroyNotify is * available to be passed. * * The following JSON fragment defines a #ClutterAlpha * using a #ClutterTimeline with id "sine-timeline" and an alpha * function called `my_sine_alpha`. The defined #ClutterAlpha * instance can be reused in multiple #ClutterBehaviour * definitions or for #ClutterAnimation definitions. * * |[ * { * "id" : "sine-alpha", * "timeline" : { * "id" : "sine-timeline", * "duration" : 500, * "loop" : true * }, * "function" : "my_sine_alpha" * } * ]| */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include #include #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "clutter-alpha.h" #include "clutter-debug.h" #include "clutter-enum-types.h" #include "clutter-easing.h" #include "clutter-main.h" #include "clutter-marshal.h" #include "clutter-private.h" #include "clutter-scriptable.h" #include "clutter-script-private.h" struct _ClutterAlphaPrivate { ClutterTimeline *timeline;

It requires that * the %CLUTTER_FEATURE_OFFSCREEN feature is supported by the current backend * and the target system. * * Some tips on usage: * * - The source actor must be visible * - The source actor must have a parent in order for it to be * allocated a size from the layouting mechanism. If the source * actor does not have a parent when this function is called then * the ClutterTexture will adopt it and allocate it at its * preferred size. Using this you can clone an actor that is * otherwise not displayed. Because of this feature if you do * intend to display the source actor then you must make sure that * the actor is parented before calling * clutter_texture_new_from_actor() or that you unparent it before * adding it to a container. * - When getting the image for the clone texture, Clutter * will attempt to render the source actor exactly as it would * appear if it was rendered on screen. The source actor's parent * transformations are taken into account. Therefore if your * source actor is rotated along the X or Y axes so that it has * some depth, the texture will appear differently depending on * the on-screen location of the source actor. While painting the * source actor, Clutter will set up a temporary asymmetric * perspective matrix as the projection matrix so that the source * actor will be projected as if a small section of the screen was * being viewed. Before version 0.8.2, an orthogonal identity * projection was used which meant that the source actor would be * clipped if any part of it was not on the zero Z-plane. * - Avoid reparenting the source with the created texture. * - A group can be padded with a transparent rectangle as to * provide a border to contents for shader output (blurring text * for example). * - The texture will automatically resize to contain a further * transformed source. However, this involves overhead and can be * avoided by placing the source actor in a bounding group * sized large enough to contain any child tranformations. * - Uploading pixel data to the texture (e.g by using * clutter_texture_set_from_file()) will destroy the offscreen texture * data and end redirection. * - cogl_texture_get_data() with the handle returned by * clutter_texture_get_cogl_texture() can be used to read the * offscreen texture pixels into a pixbuf. * * Return value: A newly created #ClutterTexture object, or %NULL on failure. * * Since: 0.6 * * Deprecated: 1.8: Use the #ClutterOffscreenEffect and #ClutterShaderEffect * directly on the intended #ClutterActor to replace the functionality of * this function. */ ClutterActor * clutter_texture_new_from_actor (ClutterActor *actor) { ClutterTexture *texture; ClutterTexturePrivate *priv; gfloat w, h; ClutterActorBox box; gboolean status; g_return_val_if_fail (CLUTTER_IS_ACTOR (actor), NULL); if (clutter_feature_available (CLUTTER_FEATURE_OFFSCREEN) == FALSE) return NULL; if (!CLUTTER_ACTOR_IS_REALIZED (actor)) { clutter_actor_realize (actor); if (!CLUTTER_ACTOR_IS_REALIZED (actor)) return NULL; } status = clutter_actor_get_paint_box (actor, &box); if (status) clutter_actor_box_get_size (&box, &w, &h); /* In the end we will size the framebuffer according to the paint * box, but for code that does: * tex = clutter_texture_new_from_actor (src); * clutter_actor_get_size (tex, &width, &height); * it seems more helpfull to return the src actor size if it has a * degenerate paint box.

For example, the "first" iterator represents the gap immediately * before the first row, and the "last" iterator represents the gap immediately * after the last row. In an empty sequence, the first and last iterators are * the same. * * |[ * enum * { * COLUMN_INT, * COLUMN_STRING. * * N_COLUMNS * }; * * { * ClutterModel *model; * ClutterModelIter *iter = NULL; * * // fill the model * model = populate_model (); * * // get the iterator for the first row in the model * iter = clutter_model_get_first_iter (model); * while (!clutter_model_iter_is_last (iter)) * { * print_row (iter); * * iter = clutter_model_iter_next (iter); * } * * // Make sure to unref the iter * g_object_unref (iter); * } * ]| * * #ClutterModel is an abstract class.

It also defines a custom * "rows" property which allows filling the #ClutterModel with some * data. * * The definition below will create a #ClutterListModel with three * columns: the first one with name "Name" and containing strings; the * second one with name "Score" and containing integers; the third one with * name "Icon" and containing #ClutterTextures.

A * behaviour is a controller object for #ClutterActors; you can * use a behaviour to control one or more properties of an actor (such * as its opacity, or its position). A #ClutterBehaviour is driven by * an "alpha function" stored inside a #ClutterAlpha object; an alpha * function is a function depending solely on time. The alpha function * computes a value which is then applied to the properties of the * actors driven by a behaviour. * * Clutter provides some pre-defined behaviours, like #ClutterBehaviourPath, * which controls the position of a set of actors making them "walk" along * a set of nodes; #ClutterBehaviourOpacity, which controls the opacity * of a set of actors; #ClutterBehaviourScale, which controls the width * and height of a set of actors. * * To visualize the effects of different alpha functions on a * #ClutterBehaviour implementation it is possible to take the * #ClutterBehaviourPath as an example: * * ![](path-alpha-func.png) * * The actors position between the path's end points directly correlates * to the #ClutterAlpha's current alpha value driving the behaviour. With * the #ClutterAlpha's function set to a linear ramp the actor * will follow the path at a constant velocity, but when changing to * a sine wave the actor initially accelerates before quickly * decelerating. * * In order to implement a new behaviour you should subclass #ClutterBehaviour * and override the "alpha_notify" virtual function; inside the overridden * function you should obtain the alpha value from the #ClutterAlpha * instance bound to the behaviour and apply it to the desiderd property * (or properties) of every actor controlled by the behaviour. * * #ClutterBehaviour is available since Clutter 0.2. * * #ClutterBehaviour and its sub-classes have been discouraged sing Clutter * 1.0, and formally deprecated since Clutter 1.6. You should use the * [implicit animation][clutter-actor-animation] support inside #ClutterActor * if you still have code using #ClutterBehaviour. */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "clutter-behaviour.h" #include "clutter-alpha.h" #include "clutter-debug.h" #include "clutter-main.h" #include "clutter-marshal.h" #include "clutter-private.h" #include "clutter-scriptable.h" #include "clutter-script-private.h" struct _ClutterBehaviourPrivate { ClutterAlpha *alpha; guint notify_id; GSList *actors; }; enum { PROP_0, PROP_ALPHA, PROP_LAST }; static GParamSpec *obj_props[PROP_LAST]; enum { APPLIED, REMOVED, LAST_SIGNAL }; static guint behave_signals[LAST_SIGNAL] = { 0 }; static void clutter_scriptable_iface_init (ClutterScriptableIface *iface); G_DEFINE_ABSTRACT_TYPE_WITH_CODE (ClutterBehaviour, clutter_behaviour, G_TYPE_OBJECT, G_ADD_PRIVATE (ClutterBehaviour) G_IMPLEMENT_INTERFACE (CLUTTER_TYPE_SCRIPTABLE, clutter_scriptable_iface_init)) static gboolean clutter_behaviour_parse_custom_node (ClutterScriptable *scriptable, ClutterScript *script, GValue *value, const gchar *name, JsonNode *node) { if (strncmp (name, "alpha", 5) == 0) { GObject *alpha; alpha = _clutter_script_parse_alpha (script, node); if (alpha != NULL) { g_value_init (value, CLUTTER_TYPE_ALPHA); g_value_set_object (value, alpha); return TRUE; } } return FALSE; } static void clutter_scriptable_iface_init (ClutterScriptableIface *iface) { iface->parse_custom_node = clutter_behaviour_parse_custom_node; } static void clutter_behaviour_dispose (GObject *gobject) { ClutterBehaviour *self = CLUTTER_BEHAVIOUR (gobject); clutter_behaviour_set_alpha (self, NULL); clutter_behaviour_remove_all (self); G_OBJECT_CLASS (clutter_behaviour_parent_class)->dispose (gobject); } static void clutter_behaviour_set_property (GObject *object, guint prop_id, const GValue *value, GParamSpec *pspec) { ClutterBehaviour *behaviour = CLUTTER_BEHAVIOUR (object); switch (prop_id) { case PROP_ALPHA: clutter_behaviour_set_alpha (behaviour, g_value_get_object (value)); break; default: G_OBJECT_WARN_INVALID_PROPERTY_ID (object, prop_id, pspec); break; } } static void clutter_behaviour_get_property (GObject *object, guint prop_id, GValue *value, GParamSpec *pspec) { ClutterBehaviour *behaviour = CLUTTER_BEHAVIOUR (object); ClutterBehaviourPrivate *priv = behaviour->priv; switch (prop_id) { case PROP_ALPHA: g_value_set_object (value, priv->alpha); break; default: G_OBJECT_WARN_INVALID_PROPERTY_ID (object, prop_id, pspec); break; } } static void clutter_behaviour_alpha_notify_unimplemented (ClutterBehaviour *behaviour, gdouble alpha_value) { g_warning ("ClutterBehaviourClass::alpha_notify not implemented for '%s'", g_type_name (G_TYPE_FROM_INSTANCE (behaviour))); } static void clutter_behaviour_class_init (ClutterBehaviourClass *klass) { GObjectClass *object_class = G_OBJECT_CLASS (klass); object_class->dispose = clutter_behaviour_dispose; object_class->set_property = clutter_behaviour_set_property; object_class->get_property = clutter_behaviour_get_property; /** * ClutterBehaviour:alpha: * * The #ClutterAlpha object used to drive this behaviour.

* - a child can also set a span, and this way, take * more than one cell both horizontally and vertically; * - each child will be allocated to its natural * size or, if set to expand, the available size; * - if a child is set to fill on either (or both) * axis, its allocation will match all the available size; the * fill layout property only makes sense if the expand property is * also set; * - if a child is set to expand but not to fill then * it is possible to control the alignment using the horizontal and * vertical alignment layout properties. * * It is possible to control the spacing between children of a * #ClutterTableLayout by using clutter_table_layout_set_row_spacing() * and clutter_table_layout_set_column_spacing(). * * In order to set the layout properties when packing an actor inside a * #ClutterTableLayout you should use the clutter_table_layout_pack() * function. * * A #ClutterTableLayout can use animations to transition between different * values of the layout management properties; the easing mode and duration * used for the animations are controlled by the * #ClutterTableLayout:easing-mode and #ClutterTableLayout:easing-duration * properties and their accessor functions. * * #ClutterTableLayout is available since Clutter 1.4 * * Since Clutter 1.18 it's recommended to use #ClutterGridLayout instead * of #ClutterTableLayout; the former supports right-to-left text direction, * as well as using the alignment and expansion flags on #ClutterActor. */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "deprecated/clutter-container.h" #include "deprecated/clutter-alpha.h" #include "clutter-table-layout.h" #include "clutter-debug.h" #include "clutter-enum-types.h" #include "clutter-layout-meta.h" #include "clutter-private.h" #include "clutter-types.h" #define CLUTTER_TYPE_TABLE_CHILD (clutter_table_child_get_type ()) #define CLUTTER_TABLE_CHILD(obj) (G_TYPE_CHECK_INSTANCE_CAST ((obj), CLUTTER_TYPE_TABLE_CHILD, ClutterTableChild)) #define CLUTTER_IS_TABLE_CHILD(obj) (G_TYPE_CHECK_INSTANCE_TYPE ((obj), CLUTTER_TYPE_TABLE_CHILD)) typedef struct _ClutterTableChild ClutterTableChild;

Each object must * have an "id" and a "type" properties defining the name to be used * to retrieve it from #ClutterScript with clutter_script_get_object(), * and the class type to be instanciated. Every other attribute will * be mapped to the class properties. * * A #ClutterScript holds a reference on every object it creates from * the definition data, except for the stage. Every non-actor object * will be finalized when the #ClutterScript instance holding it will * be finalized, so they need to be referenced using g_object_ref() in * order for them to survive. * * A simple object might be defined as: * * * * This will produce a red #ClutterRectangle, 100x100 pixels wide, and * with a ClutterScript id of "red-button"; it can be retrieved by calling: * * |[ * ClutterActor *red_button; * * red_button = CLUTTER_ACTOR (clutter_script_get_object (script, "red-button")); * ]| * * and then manipulated with the Clutter API. For every object created * using ClutterScript it is possible to check the id by calling * clutter_get_script_id(). * * Packing can be represented using the "children" member, and passing an * array of objects or ids of objects already defined (but not packed: the * packing rules of Clutter still apply, and an actor cannot be packed * in multiple containers without unparenting it in between). * * Behaviours and timelines can also be defined inside a UI definition * buffer: * * * * And then to apply a defined behaviour to an actor defined inside the * definition of an actor, the "behaviour" member can be used: * * * * A #ClutterAlpha belonging to a #ClutterBehaviour can only be defined * implicitly like in the example above, or explicitly by setting the * "alpha" property to point to a previously defined #ClutterAlpha, e.g.: * * * * Implicitely defined #ClutterAlphas and #ClutterTimelines * can omit the `id`, as well as the `type` members, but will not be available * using clutter_script_get_object() (they can, however, be extracted using the * #ClutterBehaviour and #ClutterAlpha API respectively). * * Signal handlers can be defined inside a Clutter UI definition file and * then autoconnected to their respective signals using the * clutter_script_connect_signals() function: * * * * Signal handler definitions must have a "name" and a "handler" members; * they can also have the "after" and "swapped" boolean members (for the * signal connection flags %G_CONNECT_AFTER and %G_CONNECT_SWAPPED * respectively) and the "object" string member for calling * g_signal_connect_object() instead of g_signal_connect(). * * Signals can also be directly attached to a specific state defined * inside a #ClutterState instance, for instance: * * |[ * ... * "signals" : [ * { * "name" : "enter-event", * "states" : "button-states", * "target-state" : "hover" * }, * { * "name" : "leave-event", * "states" : "button-states", * "target-state" : "base" * }, * { * "name" : "button-press-event", * "states" : "button-states", * "target-state" : "active", * }, * { * "name" : "key-press-event", * "states" : "button-states", * "target-state" : "key-focus", * "warp" : true * } * ], * ... * ]| * * The "states" key defines the #ClutterState instance to be used to * resolve the "target-state" key; it can be either a script id for a * #ClutterState built by the same #ClutterScript instance, or to a * #ClutterState built in code and associated to the #ClutterScript * instance through the clutter_script_add_states() function. If no * "states" key is present, then the default #ClutterState associated to * the #ClutterScript instance will be used; the default #ClutterState * can be set using clutter_script_add_states() using a %NULL name. The * "warp" key can be used to warp to a specific state instead of * animating to it. State changes on signal emission will not affect * the signal emission chain. * * Clutter reserves the following names, so classes defining properties * through the usual GObject registration process should avoid using these * names to avoid collisions: * * * * #ClutterScript is available since Clutter 0.6 */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include #include #include #include #include #include #include #define CLUTTER_DISABLE_DEPRECATION_WARNINGS #include "clutter-actor.h" #include "clutter-stage.h" #include "clutter-texture.h" #include "clutter-script.h" #include "clutter-script-private.h" #include "clutter-scriptable.h" #include "clutter-enum-types.h" #include "clutter-private.h" #include "clutter-debug.h" #include "deprecated/clutter-alpha.h" #include "deprecated/clutter-behaviour.h" #include "deprecated/clutter-container.h" #include "deprecated/clutter-state.h" enum { PROP_0, PROP_FILENAME_SET, PROP_FILENAME, PROP_TRANSLATION_DOMAIN, PROP_LAST }; static GParamSpec *obj_props[PROP_LAST]; #define CLUTTER_SCRIPT_GET_PRIVATE(obj) (G_TYPE_INSTANCE_GET_PRIVATE ((obj), CLUTTER_TYPE_SCRIPT, ClutterScriptPrivate)) struct _ClutterScriptPrivate { GHashTable *objects; guint last_merge_id; guint last_unknown; ClutterScriptParser *parser; GHashTable *states; gchar **search_paths; gchar *translation_domain; gchar *filename; guint is_filename : 1; }; G_DEFINE_TYPE_WITH_PRIVATE (ClutterScript, clutter_script, G_TYPE_OBJECT) static GType clutter_script_real_get_type_from_name (ClutterScript *script, const gchar *type_name) { GType gtype; gtype = g_type_from_name (type_name); if (gtype != G_TYPE_INVALID) return gtype; return _clutter_script_get_type_from_class (type_name); } void property_info_free (gpointer data) { if (G_LIKELY (data)) { PropertyInfo *pinfo = data; if (pinfo->node) json_node_free (pinfo->node); if (pinfo->pspec) g_param_spec_unref (pinfo->pspec); free (pinfo->name); g_slice_free (PropertyInfo, pinfo); } } static void signal_info_free (gpointer data) { if (G_LIKELY (data)) { SignalInfo *sinfo = data; free (sinfo->name); free (sinfo->handler); free (sinfo->object); free (sinfo->state); free (sinfo->target); g_slice_free (SignalInfo, sinfo); } } void object_info_free (gpointer data) { if (G_LIKELY (data)) { ObjectInfo *oinfo = data; free (oinfo->id); free (oinfo->class_name); free (oinfo->type_func); g_list_foreach (oinfo->properties, (GFunc) property_info_free, NULL); g_list_free (oinfo->properties); g_list_foreach (oinfo->signals, (GFunc) signal_info_free, NULL); g_list_free (oinfo->signals); /* these are ids */ g_list_foreach (oinfo->children, (GFunc) free, NULL); g_list_free (oinfo->children); /* we unref top-level objects and leave the actors alone, * unless we are unmerging in which case we have to destroy * the actor to unparent them */ if (oinfo->object != NULL) { if (oinfo->is_unmerged) { if (oinfo->is_actor && !oinfo->is_stage) clutter_actor_destroy (CLUTTER_ACTOR (oinfo->object)); } g_object_unref (oinfo->object); oinfo->object = NULL; } g_slice_free (ObjectInfo, oinfo); } } static void clutter_script_finalize (GObject *gobject) { ClutterScriptPrivate *priv = CLUTTER_SCRIPT_GET_PRIVATE (gobject); g_object_unref (priv->parser); g_hash_table_destroy (priv->objects); g_strfreev (priv->search_paths); free (priv->filename); g_hash_table_destroy (priv->states); free (priv->translation_domain); G_OBJECT_CLASS (clutter_script_parent_class)->finalize (gobject); } static void clutter_script_set_property (GObject *gobject, guint prop_id, const GValue *value, GParamSpec *pspec) { ClutterScript *script = CLUTTER_SCRIPT (gobject); switch (prop_id) { case PROP_TRANSLATION_DOMAIN: clutter_script_set_translation_domain (script, g_value_get_string (value)); break; default: G_OBJECT_WARN_INVALID_PROPERTY_ID (gobject, prop_id, pspec); break; } } static void clutter_script_get_property (GObject *gobject, guint prop_id, GValue *value, GParamSpec *pspec) { ClutterScript *script = CLUTTER_SCRIPT (gobject); switch (prop_id) { case PROP_FILENAME_SET: g_value_set_boolean (value, script->priv->is_filename); break; case PROP_FILENAME: g_value_set_string (value, script->priv->filename); break; case PROP_TRANSLATION_DOMAIN: g_value_set_string (value, script->priv->translation_domain); break; default: G_OBJECT_WARN_INVALID_PROPERTY_ID (gobject, prop_id, pspec); break; } } static void clutter_script_class_init (ClutterScriptClass *klass) { GObjectClass *gobject_class = G_OBJECT_CLASS (klass); klass->get_type_from_name = clutter_script_real_get_type_from_name; /** * ClutterScript:filename-set: * * Whether the #ClutterScript:filename property is set.

Each pointer motion during a drag will also result * in the #ClutterDragAction::drag-motion signal to be emitted. * * It is also possible to set another #ClutterActor as the dragged actor * by calling clutter_drag_action_set_drag_handle() from within a handle * of the #ClutterDragAction::drag-begin signal. The drag handle must be * parented and exist between the emission of #ClutterDragAction::drag-begin * and #ClutterDragAction::drag-end. * * The [drag-action example](https://git.gnome.org/browse/clutter/tree/examples/drag-action.c?h=clutter-1.18) * allows dragging the rectangle around the stage using a #ClutterDragAction. * When pressing the `Shift` key the actor that is being dragged will be a * separate rectangle, and when the drag ends, the original rectangle will be * animated to the final drop coordinates. * * #ClutterDragAction is available since Clutter 1.4 */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include "clutter-drag-action.h" #include "clutter-debug.h" #include "clutter-enum-types.h" #include "clutter-marshal.h" #include "clutter-private.h" #include "clutter-stage-private.h" struct _ClutterDragActionPrivate { ClutterStage *stage;

The implementation of the function should look * something like this: * * |[ * void effect_paint (ClutterEffect *effect, ClutterEffectPaintFlags flags) * { * // Set up initialisation of the paint such as binding a * // CoglOffscreen or other operations * * // Chain to the next item in the paint sequence. This will either call * // ‘paint’ on the next effect or just paint the actor if this is * // the last effect. * ClutterActor *actor = * clutter_actor_meta_get_actor (CLUTTER_ACTOR_META (effect)); * * clutter_actor_continue_paint (actor); * * // perform any cleanup of state, such as popping the CoglOffscreen * } * ]| * * The effect can optionally avoid calling clutter_actor_continue_paint() to skip any * further stages of the paint sequence. This is useful for example if the effect * contains a cached image of the actor. In that case it can optimise painting by * avoiding the actor paint and instead painting the cached image. * * The %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag is useful in this case. Clutter will set * this flag when a redraw has been queued on the actor since it was last painted. The * effect can use this information to decide if the cached image is still valid. * * ## A simple ClutterEffect implementation * * The example below creates two rectangles: one will be painted "behind" the actor, * while another will be painted "on top" of the actor. * * The #ClutterActorMetaClass.set_actor() implementation will create the two materials * used for the two different rectangles; the #ClutterEffectClass.paint() implementation * will paint the first material using cogl_rectangle(), before continuing and then it * will paint paint the second material after. * * |[ * typedef struct { * ClutterEffect parent_instance; * * CoglHandle rect_1; * CoglHandle rect_2; * } MyEffect; * * typedef struct _ClutterEffectClass MyEffectClass; * * G_DEFINE_TYPE (MyEffect, my_effect, CLUTTER_TYPE_EFFECT); * * static void * my_effect_set_actor (ClutterActorMeta *meta, * ClutterActor *actor) * { * MyEffect *self = MY_EFFECT (meta); * * // Clear the previous state // * if (self->rect_1) * { * cogl_handle_unref (self->rect_1); * self->rect_1 = NULL; * } * * if (self->rect_2) * { * cogl_handle_unref (self->rect_2); * self->rect_2 = NULL; * } * * // Maintain a pointer to the actor * self->actor = actor; * * // If we've been detached by the actor then we should just bail out here * if (self->actor == NULL) * return; * * // Create a red material * self->rect_1 = cogl_material_new (); * cogl_material_set_color4f (self->rect_1, 1.0, 0.0, 0.0, 1.0); * * // Create a green material * self->rect_2 = cogl_material_new (); * cogl_material_set_color4f (self->rect_2, 0.0, 1.0, 0.0, 1.0); * } * * static gboolean * my_effect_paint (ClutterEffect *effect) * { * MyEffect *self = MY_EFFECT (effect); * gfloat width, height; * * clutter_actor_get_size (self->actor, &width, &height); * * // Paint the first rectangle in the upper left quadrant * cogl_set_source (self->rect_1); * cogl_rectangle (0, 0, width / 2, height / 2); * * // Continue to the rest of the paint sequence * clutter_actor_continue_paint (self->actor); * * // Paint the second rectangle in the lower right quadrant * cogl_set_source (self->rect_2); * cogl_rectangle (width / 2, height / 2, width, height); * } * * static void * my_effect_class_init (MyEffectClass *klass) * { * ClutterActorMetaClas *meta_class = CLUTTER_ACTOR_META_CLASS (klass); * * meta_class->set_actor = my_effect_set_actor; * * klass->paint = my_effect_paint; * } * ]| * * #ClutterEffect is available since Clutter 1.4 */ #ifdef HAVE_CONFIG_H #include "clutter-build-config.h" #endif #include "clutter-effect.h" #include "clutter-actor-meta-private.h" #include "clutter-debug.h" #include "clutter-effect-private.h" #include "clutter-enum-types.h" #include "clutter-marshal.h" #include "clutter-private.h" #include "clutter-actor-private.h" G_DEFINE_ABSTRACT_TYPE (ClutterEffect, clutter_effect, CLUTTER_TYPE_ACTOR_META); static gboolean clutter_effect_real_pre_paint (ClutterEffect *effect) { return TRUE; } static void clutter_effect_real_post_paint (ClutterEffect *effect) { } static gboolean clutter_effect_real_get_paint_volume (ClutterEffect *effect, ClutterPaintVolume *volume) { return TRUE; } static void clutter_effect_real_paint (ClutterEffect *effect, ClutterEffectPaintFlags flags) { ClutterActorMeta *actor_meta = CLUTTER_ACTOR_META (effect); ClutterActor *actor; gboolean pre_paint_succeeded; /* The default implementation provides a compatibility wrapper for effects that haven't migrated to use the 'paint' virtual yet.

In this case a redraw wouldn't be queued on * the actor itself so the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY would still * not be set.

The order in which the transformations are * applied is decided by Clutter and it is the following: * * 1. translation by the origin of the #ClutterActor:allocation property * 2. translation by the actor's #ClutterActor:z-position property * 3. translation by the actor's #ClutterActor:pivot-point property * 4. scaling by the #ClutterActor:scale-x and #ClutterActor:scale-y factors * 5. rotation around the #ClutterActor:rotation-angle-x and #ClutterActor:rotation-center-x * 6. rotation around the #ClutterActor:rotation-angle-y and #ClutterActor:rotation-center-y * 7. rotation around the #ClutterActor:rotation-angle-z and #ClutterActor:rotation-center-z * 8. negative translation by the #ClutterActor:anchor-x and #ClutterActor:anchor-y point. * 9. negative translation by the actor's #ClutterActor:pivot-point * * ## Modifying an actor's geometry ## {#clutter-actor-geometry} * * Each actor has a bounding box, called #ClutterActor:allocation * which is either set by its parent or explicitly through the * clutter_actor_set_position() and clutter_actor_set_size() methods. * Each actor also has an implicit preferred size. * * An actor’s preferred size can be defined by any subclass by * overriding the #ClutterActorClass.get_preferred_width() and the * #ClutterActorClass.get_preferred_height() virtual functions, or it can * be explicitly set by using clutter_actor_set_width() and * clutter_actor_set_height(). * * An actor’s position can be set explicitly by using * clutter_actor_set_x() and clutter_actor_set_y(); the coordinates are * relative to the origin of the actor’s parent. * * ## Managing actor children ## {#clutter-actor-children} * * Each actor can have multiple children, by calling * clutter_actor_add_child() to add a new child actor, and * clutter_actor_remove_child() to remove an existing child. #ClutterActor * will hold a reference on each child actor, which will be released when * the child is removed from its parent, or destroyed using * clutter_actor_destroy(). * * |[ * ClutterActor *actor = clutter_actor_new (); * * // set the bounding box of the actor * clutter_actor_set_position (actor, 0, 0); * clutter_actor_set_size (actor, 480, 640); * * // set the background color of the actor * clutter_actor_set_background_color (actor, CLUTTER_COLOR_Orange); * * // set the bounding box of the child, relative to the parent * ClutterActor *child = clutter_actor_new (); * clutter_actor_set_position (child, 20, 20); * clutter_actor_set_size (child, 80, 240); * * // set the background color of the child * clutter_actor_set_background_color (child, CLUTTER_COLOR_Blue); * * // add the child to the actor * clutter_actor_add_child (actor, child); * ]| * * Children can be inserted at a given index, or above and below * another child actor. The order of insertion determines the order of the * children when iterating over them. Iterating over children is performed * by using clutter_actor_get_first_child(), clutter_actor_get_previous_sibling(), * clutter_actor_get_next_sibling(), and clutter_actor_get_last_child(). It is * also possible to retrieve a list of children by using * clutter_actor_get_children(), as well as retrieving a specific child at a * given index by using clutter_actor_get_child_at_index(). * * If you need to track additions of children to a #ClutterActor, use * the #ClutterContainer::actor-added signal; similarly, to track removals * of children from a ClutterActor, use the #ClutterContainer::actor-removed * signal. * * See [basic-actor.c](https://git.gnome.org/browse/clutter/tree/examples/basic-actor.c?h=clutter-1.18). * * ## Painting an actor ## {#clutter-actor-painting} * * There are three ways to paint an actor: * * - set a delegate #ClutterContent as the value for the #ClutterActor:content property of the actor * - subclass #ClutterActor and override the #ClutterActorClass.paint_node() virtual function * - subclass #ClutterActor and override the #ClutterActorClass.paint() virtual function. * * A #ClutterContent is a delegate object that takes over the painting * operations of one, or more actors. The #ClutterContent painting will * be performed on top of the #ClutterActor:background-color of the actor, * and before calling the actor's own implementation of the * #ClutterActorClass.paint_node() virtual function. * * |[ * ClutterActor *actor = clutter_actor_new (); * * // set the bounding box * clutter_actor_set_position (actor, 50, 50); * clutter_actor_set_size (actor, 100, 100); * * // set the content; the image_content variable is set elsewhere * clutter_actor_set_content (actor, image_content); * ]| * * The #ClutterActorClass.paint_node() virtual function is invoked whenever * an actor needs to be painted. The implementation of the virtual function * must only paint the contents of the actor itself, and not the contents of * its children, if the actor has any. * * The #ClutterPaintNode passed to the virtual function is the local root of * the render tree; any node added to it will be rendered at the correct * position, as defined by the actor's #ClutterActor:allocation. * * |[ * static void * my_actor_paint_node (ClutterActor *actor, * ClutterPaintNode *root) * { * ClutterPaintNode *node; * ClutterActorBox box; * * // where the content of the actor should be painted * clutter_actor_get_allocation_box (actor, &box); * * // the cogl_texture variable is set elsewhere * node = clutter_texture_node_new (cogl_texture, CLUTTER_COLOR_White, * CLUTTER_SCALING_FILTER_TRILINEAR, * CLUTTER_SCALING_FILTER_LINEAR); * * // paint the content of the node using the allocation * clutter_paint_node_add_rectangle (node, &box); * * // add the node, and transfer ownership * clutter_paint_node_add_child (root, node); * clutter_paint_node_unref (node); * } * * The #ClutterActorClass.paint() virtual function is invoked when the * #ClutterActor::paint signal is emitted, and after the other signal * handlers have been invoked. Overriding the paint virtual function * gives total control to the paint sequence of the actor itself, * including the children of the actor, if any. * * It is strongly discouraged to override the #ClutterActorClass.paint() * virtual function, as well as connecting to the #ClutterActor::paint * signal. These hooks into the paint sequence are considered legacy, and * will be removed when the Clutter API changes. * * ## Handling events on an actor ## {#clutter-actor-event-handling} * * A #ClutterActor can receive and handle input device events, for * instance pointer events and key events, as long as its * #ClutterActor:reactive property is set to %TRUE. * * Once an actor has been determined to be the source of an event, * Clutter will traverse the scene graph from the top-level actor towards the * event source, emitting the #ClutterActor::captured-event signal on each * ancestor until it reaches the source; this phase is also called * the "capture" phase. If the event propagation was not stopped, the graph * is walked backwards, from the source actor to the top-level, and the * #ClutterActor::event signal is emitted, alongside eventual event-specific * signals like #ClutterActor::button-press-event or #ClutterActor::motion-event; * this phase is also called the "bubble" phase. * * At any point of the signal emission, signal handlers can stop the propagation * through the scene graph by returning %CLUTTER_EVENT_STOP; otherwise, they can * continue the propagation by returning %CLUTTER_EVENT_PROPAGATE. * * ## Animation ## {#clutter-actor-animation} * * Animation is a core concept of modern user interfaces; Clutter provides a * complete and powerful animation framework that automatically tweens the * actor's state without requiring direct, frame by frame manipulation from * your application code. You have two models at your disposal: * * - an implicit animation model * - an explicit animation model * * The implicit animation model of Clutter assumes that all the * changes in an actor state should be gradual and asynchronous; Clutter * will automatically transition an actor's property change between the * current state and the desired one without manual intervention, if the * property is defined to be animatable in its documentation. * * By default, in the 1.0 API series, the transition happens with a duration * of zero milliseconds, and the implicit animation is an opt in feature to * retain backwards compatibility. * * Implicit animations depend on the current easing state; in order to use * the default easing state for an actor you should call the * clutter_actor_save_easing_state() function: * * |[ * // assume that the actor is currently positioned at (100, 100) * * // store the current easing state and reset the new easing state to * // its default values * clutter_actor_save_easing_state (actor); * * // change the actor's position * clutter_actor_set_position (actor, 500, 500); * * // restore the previously saved easing state * clutter_actor_restore_easing_state (actor); * ]| * * The example above will trigger an implicit animation of the * actor between its current position to a new position. * * Implicit animations use a default duration of 250 milliseconds, * and a default easing mode of %CLUTTER_EASE_OUT_CUBIC, unless you call * clutter_actor_set_easing_mode() and clutter_actor_set_easing_duration() * after changing the easing state of the actor. * * It is possible to animate multiple properties of an actor * at the same time, and you can animate multiple actors at the same * time as well, for instance: * * |[ * clutter_actor_save_easing_state (actor); * * // animate the actor's opacity and depth * clutter_actor_set_opacity (actor, 0); * clutter_actor_set_depth (actor, -100); * * clutter_actor_restore_easing_state (actor); * * clutter_actor_save_easing_state (another_actor); * * // animate another actor's opacity * clutter_actor_set_opacity (another_actor, 255); * clutter_actor_set_depth (another_actor, 100); * * clutter_actor_restore_easing_state (another_actor); * ]| * * Changing the easing state will affect all the following property * transitions, but will not affect existing transitions. * * It is important to note that if you modify the state on an * animatable property while a transition is in flight, the transition's * final value will be updated, as well as its duration and progress * mode by using the current easing state; for instance, in the following * example: * * |[ * clutter_actor_save_easing_state (actor); * clutter_actor_set_easing_duration (actor, 1000); * clutter_actor_set_x (actor, 200); * clutter_actor_restore_easing_state (actor); * * clutter_actor_save_easing_state (actor); * clutter_actor_set_easing_duration (actor, 500); * clutter_actor_set_x (actor, 100); * clutter_actor_restore_easing_state (actor); * ]| * * the first call to clutter_actor_set_x() will begin a transition * of the #ClutterActor:x property from the current value to the value of * 200 over a duration of one second; the second call to clutter_actor_set_x() * will change the transition's final value to 100 and the duration to 500 * milliseconds. * * It is possible to receive a notification of the completion of an * implicit transition by using the #ClutterActor::transition-stopped * signal, decorated with the name of the property. In case you want to * know when all the currently in flight transitions are complete, use * the #ClutterActor::transitions-completed signal instead. * * It is possible to retrieve the #ClutterTransition used by the * animatable properties by using clutter_actor_get_transition() and using * the property name as the transition name. * * The explicit animation model supported by Clutter requires that * you create a #ClutterTransition object, and optionally set the initial * and final values. The transition will not start unless you add it to the * #ClutterActor. * * |[ * ClutterTransition *transition; * * transition = clutter_property_transition_new ("opacity"); * clutter_timeline_set_duration (CLUTTER_TIMELINE (transition), 3000); * clutter_timeline_set_repeat_count (CLUTTER_TIMELINE (transition), 2); * clutter_timeline_set_auto_reverse (CLUTTER_TIMELINE (transition), TRUE); * clutter_transition_set_from (transition, G_TYPE_UINT, 255); * clutter_transition_set_to (transition, G_TYPE_UINT, 0); * * clutter_actor_add_transition (actor, "animate-opacity", transition); * ]| * * The example above will animate the #ClutterActor:opacity property * of an actor between fully opaque and fully transparent, and back, over * a span of 3 seconds. The animation does not begin until it is added to * the actor. * * The explicit animation API applies to all #GObject properties, * as well as the custom properties defined through the #ClutterAnimatable * interface, regardless of whether they are defined as implicitly * animatable or not. * * The explicit animation API should also be used when using custom * animatable properties for #ClutterAction, #ClutterConstraint, and * #ClutterEffect instances associated to an actor; see the section on * custom animatable properties below for an example. * * Finally, explicit animations are useful for creating animations * that run continuously, for instance: * * |[ * // this animation will pulse the actor's opacity continuously * ClutterTransition *transition; * ClutterInterval *interval; * * transition = clutter_property_transition_new ("opacity"); * * // we want to animate the opacity between 0 and 255 * clutter_transition_set_from (transition, G_TYPE_UINT, 0); * clutter_transition_set_to (transition, G_TYPE_UINT, 255); * * // over a one second duration, running an infinite amount of times * clutter_timeline_set_duration (CLUTTER_TIMELINE (transition), 1000); * clutter_timeline_set_repeat_count (CLUTTER_TIMELINE (transition), -1); * * // we want to fade in and out, so we need to auto-reverse the transition * clutter_timeline_set_auto_reverse (CLUTTER_TIMELINE (transition), TRUE); * * // and we want to use an easing function that eases both in and out * clutter_timeline_set_progress_mode (CLUTTER_TIMELINE (transition), * CLUTTER_EASE_IN_OUT_CUBIC); * * // add the transition to the desired actor to start it * clutter_actor_add_transition (actor, "opacityAnimation", transition); * ]| * * ## Implementing an actor ## {#clutter-actor-implementing} * * Careful consideration should be given when deciding to implement * a #ClutterActor sub-class. It is generally recommended to implement a * sub-class of #ClutterActor only for actors that should be used as leaf * nodes of a scene graph. * * If your actor should be painted in a custom way, you should * override the #ClutterActor::paint signal class handler. You can either * opt to chain up to the parent class implementation or decide to fully * override the default paint implementation; Clutter will set up the * transformations and clip regions prior to emitting the #ClutterActor::paint * signal. * * By overriding the #ClutterActorClass.get_preferred_width() and * #ClutterActorClass.get_preferred_height() virtual functions it is * possible to change or provide the preferred size of an actor; similarly, * by overriding the #ClutterActorClass.allocate() virtual function it is * possible to control the layout of the children of an actor. Make sure to * always chain up to the parent implementation of the * #ClutterActorClass.allocate() virtual function. * * In general, it is strongly encouraged to use delegation and composition * instead of direct subclassing. * * ## ClutterActor custom properties for ClutterScript ## {#clutter-actor-custom-script} * * #ClutterActor defines a custom "rotation" property which allows a short-hand * description of the rotations to be applied to an actor. * * The syntax of the "rotation" property is the following: * * |[ * "rotation" : [ { "" : [ , [ ] ] } ] * ]| * * where: * * - axis is the name of an enumeration value of type #ClutterRotateAxis * - angle is a floating point value representing the rotation angle on the given axis in degrees * - center-point is an optional array, and if present it must contain the center of rotation as described by two coordinates: * - Y and Z for "x-axis" * - X and Z for "y-axis" * - X and Y for "z-axis". * * #ClutterActor also defines a scriptable "margin" property which follows the CSS "margin" shorthand. * * |[ * // 4 values * "margin" : [ top, right, bottom, left ] * // 3 values * "margin" : [ top, left/right, bottom ] * // 2 values * "margin" : [ top/bottom, left/right ] * // 1 value * "margin" : [ top/right/bottom/left ] * ]| * * #ClutterActor will also parse every positional and dimensional * property defined as a string through clutter_units_from_string(); you * should read the documentation for the #ClutterUnits parser format for * the valid units and syntax. * * ## Custom animatable properties * * #ClutterActor allows accessing properties of #ClutterAction, * #ClutterEffect, and #ClutterConstraint instances associated to an actor * instance for animation purposes. * * In order to access a specific #ClutterAction or a #ClutterConstraint * property it is necessary to set the #ClutterActorMeta:name property on the * given action or constraint. * * The property can be accessed using the following syntax: * * |[ * @
.. * ]| * * - the initial `@` is mandatory * - the `section` fragment can be one between "actions", "constraints" and "effects" * - the `meta-name` fragment is the name of the action, effect, or constraint, as * specified by the #ClutterActorMeta:name property of #ClutterActorMeta * - the `property-name` fragment is the name of the action, effect, or constraint * property to be animated. * * The example below animates a #ClutterBindConstraint applied to an actor * using an explicit transition. The `rect` actor has a binding constraint * on the `origin` actor, and in its initial state is overlapping the actor * to which is bound to. * * |[ * constraint = clutter_bind_constraint_new (origin, CLUTTER_BIND_X, 0.0); * clutter_actor_meta_set_name (CLUTTER_ACTOR_META (constraint), "bind-x"); * clutter_actor_add_constraint (rect, constraint); * * constraint = clutter_bind_constraint_new (origin, CLUTTER_BIND_Y, 0.0); * clutter_actor_meta_set_name (CLUTTER_ACTOR_META (constraint), "bind-y"); * clutter_actor_add_constraint (rect, constraint); * * clutter_actor_set_reactive (origin, TRUE); * * g_signal_connect (origin, "button-press-event", * G_CALLBACK (on_button_press), * rect); * ]| * * On button press, the rectangle "slides" from behind the actor to * which is bound to, using the #ClutterBindConstraint:offset property to * achieve the effect: * * |[ * gboolean * on_button_press (ClutterActor *origin, * ClutterEvent *event, * ClutterActor *rect) * { * ClutterTransition *transition; * * // the offset that we want to apply; this will make the actor * // slide in from behind the origin and rest at the right of * // the origin, plus a padding value * float new_offset = clutter_actor_get_width (origin) + h_padding; * * // the property we wish to animate; the "@constraints" section * // tells Clutter to check inside the constraints associated * // with the actor; the "bind-x" section is the name of the * // constraint; and the "offset" is the name of the property * // on the constraint * const char *prop = "@constraints.bind-x.offset"; * * // create a new transition for the given property * transition = clutter_property_transition_new (prop); * * // set the easing mode and duration * clutter_timeline_set_progress_mode (CLUTTER_TIMELINE (transition), * CLUTTER_EASE_OUT_CUBIC); * clutter_timeline_set_duration (CLUTTER_TIMELINE (transition), 500); * * // create the interval with the initial and final values * clutter_transition_set_from (transition, G_TYPE_FLOAT, 0.f); * clutter_transition_set_to (transition, G_TYPE_FLOAT, new_offset); * * // add the transition to the actor; this causes the animation * // to start. the name "offsetAnimation" can be used to retrieve * // the transition later * clutter_actor_add_transition (rect, "offsetAnimation", transition); * * // we handled the event * return CLUTTER_EVENT_STOP; * } * ]| */ /** * CLUTTER_ACTOR_IS_MAPPED: * @a: a #ClutterActor * * Evaluates to %TRUE if the %CLUTTER_ACTOR_MAPPED flag is set. * * The mapped state is set when the actor is visible and all its parents up * to a top-level (e.g. a #ClutterStage) are visible, realized, and mapped. * * This check can be used to see if an actor is going to be painted, as only * actors with the %CLUTTER_ACTOR_MAPPED flag set are going to be painted. * * The %CLUTTER_ACTOR_MAPPED flag is managed by Clutter itself, and it should * not be checked directly; instead, the recommended usage is to connect a * handler on the #GObject::notify signal for the #ClutterActor:mapped * property of #ClutterActor, and check the presence of * the %CLUTTER_ACTOR_MAPPED flag on state changes. * * It is also important to note that Clutter may delay the changes of * the %CLUTTER_ACTOR_MAPPED flag on top-levels due to backend-specific * limitations, or during the reparenting of an actor, to optimize * unnecessary (and potentially expensive) state changes. * * Since: 0.2 * * Deprecated: 1.24: Use clutter_actor_is_mapped() or the #ClutterActor:mapped * property instead of this macro. */ /** * CLUTTER_ACTOR_IS_REALIZED: * @a: a #ClutterActor * * Evaluates to %TRUE if the %CLUTTER_ACTOR_REALIZED flag is set. * * The realized state has an actor-dependant interpretation.

Secondly, it will make * the opacity look correct even if there are overlapping primitives * in the actor. * * Caching the actor could in some cases be a performance win and in * some cases be a performance lose so it is important to determine * which value is right for an actor before modifying this value. For * example, there is never any reason to flatten an actor that is just * a single texture (such as a #ClutterTexture) because it is * effectively already cached in an image so the offscreen would be * redundant. Also if the actor contains primitives that are far apart * with a large transparent area in the middle (such as a large * CluterGroup with a small actor in the top left and a small actor in * the bottom right) then the cached image will contain the entire * image of the large area and the paint will waste time blending all * of the transparent pixels in the middle. * * The default method of implementing opacity on a container simply * forwards on the opacity to all of the children. If the children are * overlapping then it will appear as if they are two separate glassy * objects and there will be a break in the color where they * overlap. By redirecting to an offscreen buffer it will be as if the * two opaque objects are combined into one and then made transparent * which is usually what is expected. * * The image below demonstrates the difference between redirecting and * not. The image shows two Clutter groups, each containing a red and * a green rectangle which overlap. The opacity on the group is set to * 128 (which is 50%). When the offscreen redirect is not used, the * red rectangle can be seen through the blue rectangle as if the two * rectangles were separately transparent. When the redirect is used * the group as a whole is transparent instead so the red rectangle is * not visible where they overlap. * *
* Sample of using an offscreen redirect for transparency * *
* * The default value for this property is 0, so we effectively will * never redirect an actor offscreen by default. This means that there * are times that transparent actors may look glassy as described * above. The reason this is the default is because there is a * performance trade off between quality and performance here. In many * cases the default form of glassy opacity looks good enough, but if * it's not you will need to set the * %CLUTTER_OFFSCREEN_REDIRECT_AUTOMATIC_FOR_OPACITY flag to enable * redirection for opacity. * * Custom actors that don't contain any overlapping primitives are * recommended to override the has_overlaps() virtual to return %FALSE * for maximum efficiency. * * Since: 1.8 */ void clutter_actor_set_offscreen_redirect (ClutterActor *self, ClutterOffscreenRedirect redirect) { ClutterActorPrivate *priv; g_return_if_fail (CLUTTER_IS_ACTOR (self)); priv = self->priv; if (priv->offscreen_redirect != redirect) { priv->offscreen_redirect = redirect; /* Queue a redraw from the effect so that it can use its cached image if available instead of having to redraw the actual actor.

This is used for support programs/scripts # that should not themselves be run as testcases (but exist to be used from other testcases): # # test_extra_programs, installed_test_extra_programs, uninstalled_test_extra_programs # test_extra_scripts, installed_test_extra_scripts, uninstalled_test_extra_scripts # # Additionally, for _scripts and _data, we support the customary dist_ prefix so that the named script or data # file automatically end up in the tarball. # # dist_test_scripts, dist_test_data, dist_test_extra_scripts # dist_installed_test_scripts, dist_installed_test_data, dist_installed_test_extra_scripts # dist_uninstalled_test_scripts, dist_uninstalled_test_data, dist_uninstalled_test_extra_scripts # # Note that no file is automatically disted unless it appears in one of the dist_ variables. This follows the # standard automake convention of not disting programs scripts or data by default. # # test_programs, test_scripts, uninstalled_test_programs and uninstalled_test_scripts (as well as their disted # variants) will be run as part of the in-tree 'make check'. These are all assumed to be runnable under # gtester. That's a bit strange for scripts, but it's possible.

See conform/ADDING_NEW_TESTS for more details. Although it may seem a bit awkward; all the tests are built into a single binary because it makes building the tests *much* faster by avoiding lots of linking. Each test has a wrapper script generated though so running the individual tests should be convenient enough. Running the wrapper script will also print out for convenience how you could run the test under gdb or valgrind like this for example: NOTE: For debugging purposes, you can run this single test as follows: $ libtool --mode=execute \ gdb --eval-command="b test_cogl_depth_test" \ --args ./test-conformance -p /conform/cogl/test_cogl_depth_test or: $ env G_SLICE=always-malloc \ libtool --mode=execute \ valgrind ./test-conformance -p /conform/cogl/test_cogl_depth_test By default the conformance tests are run offscreen. This makes the tests run much faster and they also don't interfere with other work you may want to do by constantly stealing focus. CoglOnscreen framebuffers obviously don't get tested this way so it's important that the tests also get run onscreen every once in a while, especially if changes are being made to CoglFramebuffer related code. Onscreen testing can be enabled by setting COGL_TEST_ONSCREEN=1 in your environment. The micro-bench/ tests: ----------------------- These should be focused performance tests, ideally testing a single metric. Please never forget that these tests are synthetic and if you are using them then you understand what metric is being tested. They probably don't reflect any real world application loads and the intention is that you use these tests once you have already determined the crux of your problem and need focused feedback that your changes are indeed improving matters. There is no exit status requirements for these tests, but they should give clear feedback as to their performance.

It is backward-compatible with the current OpenGL Utilities tesselator, and is intended to replace it. Here is a summary of the major differences: - input contours can be intersecting, self-intersecting, or degenerate. - supports a choice of several winding rules for determining which parts of the polygon are on the "interior". This makes it possible to do CSG operations on polygons. - boundary extraction: instead of tesselating the polygon, returns a set of closed contours which separate the interior from the exterior. - returns the output as a small number of triangle fans and strips, rather than a list of independent triangles (when possible). - output is available as an explicit mesh (a quad-edge structure), in addition to the normal callback interface. - the algorithm used is extremely robust. The interface ------------- The tesselator state is maintained in a "tesselator object". These are allocated and destroyed using GLUtesselator *gluNewTess( void ); void gluDeleteTess( GLUtesselator *tess ); Several tesselator objects may be used simultaneously. Inputs ------ The input contours are specified with the following routines: void gluTessBeginPolygon( GLUtesselator *tess ); void gluTessBeginContour( GLUtesselator *tess ); void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data ); void gluTessEndContour( GLUtesselator *tess ); void gluTessEndPolygon( GLUtesselator *tess ); Within each BeginPolygon/EndPolygon pair, there can be zero or more calls to BeginContour/EndContour. Within each contour, there are zero or more calls to gluTessVertex(). The vertices specify a closed contour (the last vertex of each contour is automatically linked to the first). "coords" give the coordinates of the vertex in 3-space. For useful results, all vertices should lie in some plane, since the vertices are projected onto a plane before tesselation. "data" is a pointer to a user-defined vertex structure, which typically contains other information such as color, texture coordinates, normal, etc. It is used to refer to the vertex during rendering. The library can be compiled in single- or double-precision; the type GLUcoord represents either "float" or "double" accordingly. The GLU version will be available in double-precision only. Compile with GLU_TESS_API_FLOAT defined to get the single-precision version. When EndPolygon is called, the tesselation algorithm determines which regions are interior to the given contours, according to one of several "winding rules" described below. The interior regions are then tesselated, and the output is provided as callbacks. Rendering Callbacks ------------------- Callbacks are specified by the client using void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)()); If "fn" is NULL, any previously defined callback is discarded. The callbacks used to provide output are: /* which == */ void begin( GLenum type ); /* GLU_TESS_BEGIN */ void edgeFlag( GLboolean flag ); /* GLU_TESS_EDGE_FLAG */ void vertex( void *data ); /* GLU_TESS_VERTEX */ void end( void ); /* GLU_TESS_END */ Any of the callbacks may be left undefined; if so, the corresponding information will not be supplied during rendering. The "begin" callback indicates the start of a primitive; type is one of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the notes on "boundary extraction" below). It is followed by any number of "vertex" callbacks, which supply the vertices in the same order as expected by the corresponding glBegin() call. After the last vertex of a given primitive, there is a callback to "end". If the "edgeFlag" callback is provided, no triangle fans or strips will be used. When edgeFlag is called, if "flag" is GL_TRUE then each vertex which follows begins an edge which lies on the polygon boundary (ie. an edge which separates an interior region from an exterior one). If "flag" is GL_FALSE, each vertex which follows begins an edge which lies in the polygon interior. "edgeFlag" will be called before the first call to "vertex". Other Callbacks --------------- void mesh( GLUmesh *mesh ); /* GLU_TESS_MESH */ - Returns an explicit mesh, represented using the quad-edge structure (Guibas/Stolfi '85). Other implementations of this interface might use a different mesh structure, so this is available only only as an SGI extension. When the mesh is no longer needed, it should be freed using void gluDeleteMesh( GLUmesh *mesh ); There is a brief description of this data structure in the include file "mesh.h". For the full details, see L. Guibas and J. Stolfi, Primitives for the manipulation of general subdivisions and the computation of Voronoi diagrams, ACM Transactions on Graphics, 4(2):74-123, April 1985. For an introduction, see the course notes for CS348a, "Mathematical Foundations of Computer Graphics", available at the Stanford bookstore (and taught during the fall quarter). void error( GLenum errno ); /* GLU_TESS_ERROR */ - errno is one of GLU_TESS_MISSING_BEGIN_POLYGON, GLU_TESS_MISSING_END_POLYGON, GLU_TESS_MISSING_BEGIN_CONTOUR, GLU_TESS_MISSING_END_CONTOUR, GLU_TESS_COORD_TOO_LARGE, GLU_TESS_NEED_COMBINE_CALLBACK The first four are obvious. The interface recovers from these errors by inserting the missing call(s). GLU_TESS_COORD_TOO_LARGE says that some vertex coordinate exceeded the predefined constant GLU_TESS_MAX_COORD in absolute value, and that the value has been clamped. (Coordinate values must be small enough so that two can be multiplied together without overflow.) GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an intersection between two edges in the input data, and the "combine" callback (below) was not provided. No output will be generated. void combine( GLUcoord coords[3], void *data[4], /* GLU_TESS_COMBINE */ GLUcoord weight[4], void **outData ); - When the algorithm detects an intersection, or wishes to merge features, it needs to create a new vertex. The vertex is defined as a linear combination of up to 4 existing vertices, referenced by data[0..3]. The coefficients of the linear combination are given by weight[0..3]; these weights always sum to 1.0. All vertex pointers are valid even when some of the weights are zero. "coords" gives the location of the new vertex. The user must allocate another vertex, interpolate parameters using "data" and "weights", and return the new vertex pointer in "outData". This handle is supplied during rendering callbacks. For example, if the polygon lies in an arbitrary plane in 3-space, and we associate a color with each vertex, the combine callback might look like this: void myCombine( GLUcoord coords[3], VERTEX *d[4], GLUcoord w[4], VERTEX **dataOut ) { VERTEX *new = new_vertex(); new->x = coords[0]; new->y = coords[1]; new->z = coords[2]; new->r = w[0]*d[0]->r + w[1]*d[1]->r + w[2]*d[2]->r + w[3]*d[3]->r; new->g = w[0]*d[0]->g + w[1]*d[1]->g + w[2]*d[2]->g + w[3]*d[3]->g; new->b = w[0]*d[0]->b + w[1]*d[1]->b + w[2]*d[2]->b + w[3]*d[3]->b; new->a = w[0]*d[0]->a + w[1]*d[1]->a + w[2]*d[2]->a + w[3]*d[3]->a; *dataOut = new; } If the algorithm detects an intersection, then the "combine" callback must be defined, and must write a non-NULL pointer into "dataOut". Otherwise the GLU_TESS_NEED_COMBINE_CALLBACK error occurs, and no output is generated. This is the only error that can occur during tesselation and rendering. Control over Tesselation ------------------------ void gluTessProperty( GLUtesselator *tess, GLenum which, GLUcoord value ); Properties defined: - GLU_TESS_WINDING_RULE. Possible values: GLU_TESS_WINDING_ODD GLU_TESS_WINDING_NONZERO GLU_TESS_WINDING_POSITIVE GLU_TESS_WINDING_NEGATIVE GLU_TESS_WINDING_ABS_GEQ_TWO The input contours parition the plane into regions. A winding rule determines which of these regions are inside the polygon. For a single contour C, the winding number of a point x is simply the signed number of revolutions we make around x as we travel once around C (where CCW is positive). When there are several contours, the individual winding numbers are summed. This procedure associates a signed integer value with each point x in the plane. Note that the winding number is the same for all points in a single region. The winding rule classifies a region as "inside" if its winding number belongs to the chosen category (odd, nonzero, positive, negative, or absolute value of at least two). The current GLU tesselator implements the "odd" rule. The "nonzero" rule is another common way to define the interior. The other three rules are useful for polygon CSG operations (see below). - GLU_TESS_BOUNDARY_ONLY. Values: TRUE (non-zero) or FALSE (zero). If TRUE, returns a set of closed contours which separate the polygon interior and exterior (rather than a tesselation). Exterior contours are oriented CCW with respect to the normal, interior contours are oriented CW. The GLU_TESS_BEGIN callback uses the type GL_LINE_LOOP for each contour. - GLU_TESS_TOLERANCE. Value: a real number between 0.0 and 1.0. This specifies a tolerance for merging features to reduce the size of the output. For example, two vertices which are very close to each other might be replaced by a single vertex. The tolerance is multiplied by the largest coordinate magnitude of any input vertex; this specifies the maximum distance that any feature can move as the result of a single merge operation. If a single feature takes part in several merge operations, the total distance moved could be larger. Feature merging is completely optional; the tolerance is only a hint. The implementation is free to merge in some cases and not in others, or to never merge features at all. The default tolerance is zero. The current implementation merges vertices only if they are exactly coincident, regardless of the current tolerance. A vertex is spliced into an edge only if the implementation is unable to distinguish which side of the edge the vertex lies on. Two edges are merged only when both endpoints are identical. void gluTessNormal( GLUtesselator *tess, GLUcoord x, GLUcoord y, GLUcoord z ) - Lets the user supply the polygon normal, if known. All input data is projected into a plane perpendicular to the normal before tesselation. All output triangles are oriented CCW with respect to the normal (CW orientation can be obtained by reversing the sign of the supplied normal). For example, if you know that all polygons lie in the x-y plane, call "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons. - If the supplied normal is (0,0,0) (the default value), the normal is determined as follows. The direction of the normal, up to its sign, is found by fitting a plane to the vertices, without regard to how the vertices are connected. It is expected that the input data lies approximately in plane; otherwise projection perpendicular to the computed normal may substantially change the geometry. The sign of the normal is chosen so that the sum of the signed areas of all input contours is non-negative (where a CCW contour has positive area). - The supplied normal persists until it is changed by another call to gluTessNormal. Backward compatibility with the GLU tesselator ---------------------------------------------- The preferred interface is the one described above. The following routines are obsolete, and are provided only for backward compatibility: typedef GLUtesselator GLUtriangulatorObj; /* obsolete name */ void gluBeginPolygon( GLUtesselator *tess ); void gluNextContour( GLUtesselator *tess, GLenum type ); void gluEndPolygon( GLUtesselator *tess ); "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or GLU_UNKNOWN. It is ignored by the current GLU tesselator. GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END, GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG. Polygon CSG operations ---------------------- The features of the tesselator make it easy to find the union, difference, or intersection of several polygons. First, assume that each polygon is defined so that the winding number is 0 for each exterior region, and 1 for each interior region. Under this model, CCW contours define the outer boundary of the polygon, and CW contours define holes. Contours may be nested, but a nested contour must be oriented oppositely from the contour that contains it. If the original polygons do not satisfy this description, they can be converted to this form by first running the tesselator with the GLU_TESS_BOUNDARY_ONLY property turned on. This returns a list of contours satisfying the restriction above. By allocating two tesselator objects, the callbacks from one tesselator can be fed directly to the input of another. Given two or more polygons of the form above, CSG operations can be implemented as follows: Union Draw all the input contours as a single polygon. The winding number of each resulting region is the number of original polygons which cover it. The union can be extracted using the GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules. Note that with the nonzero rule, we would get the same result if all contour orientations were reversed. Intersection (two polygons at a time only) Draw a single polygon using the contours from both input polygons. Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO. (Since this winding rule looks at the absolute value, reversing all contour orientations does not change the result.) Difference Suppose we want to compute A \ (B union C union D). Draw a single polygon consisting of the unmodified contours from A, followed by the contours of B,C,D with the vertex order reversed (this changes the winding number of the interior regions to -1). To extract the result, use the GLU_TESS_WINDING_POSITIVE rule. If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an alternative to reversing the vertex order is to reverse the sign of the supplied normal. For example in the x-y plane, call gluTessNormal( tess, 0.0, 0.0, -1.0 ). Performance ----------- The tesselator is not intended for immediate-mode rendering; when possible the output should be cached in a user structure or display list. General polygon tesselation is an inherently difficult problem, especially given the goal of extreme robustness. The implementation makes an effort to output a small number of fans and strips; this should improve the rendering performance when the output is used in a display list. Single-contour input polygons are first tested to see whether they can be rendered as a triangle fan with respect to the first vertex (to avoid running the full decomposition algorithm on convex polygons). Non-convex polygons may be rendered by this "fast path" as well, if the algorithm gets lucky in its choice of a starting vertex. For best performance follow these guidelines: - supply the polygon normal, if available, using gluTessNormal(). This represents about 10% of the computation time. For example, if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1). - render many polygons using the same tesselator object, rather than allocating a new tesselator for each one. (In a multi-threaded, multi-processor environment you may get better performance using several tesselators.) Comparison with the GLU tesselator ---------------------------------- On polygons which make it through the "fast path", the tesselator is 3 to 5 times faster than the GLU tesselator. On polygons which don't make it through the fast path (but which don't have self-intersections or degeneracies), it is about 2 times slower. On polygons with self-intersections or degeneraces, there is nothing to compare against. The new tesselator generates many more fans and strips, reducing the number of vertices that need to be sent to the hardware.

Guibas and J. Stolfi, Primitives * for the manipulation of general subdivisions and the computation of * Voronoi diagrams, ACM Transactions on Graphics, 4(2):74-123, April 1985). * For a simplified description, see the course notes for CS348a, * "Mathematical Foundations of Computer Graphics", available at the * Stanford bookstore (and taught during the fall quarter). * The implementation also borrows a tiny subset of the graph-based approach * use in Mantyla's Geometric Work Bench (see M. Mantyla, An Introduction * to Sold Modeling, Computer Science Press, Rockville, Maryland, 1988). * * The fundamental data structure is the "half-edge". Two half-edges * go together to make an edge, but they point in opposite directions. * Each half-edge has a pointer to its mate (the "symmetric" half-edge Sym), * its origin vertex (Org), the face on its left side (Lface), and the * adjacent half-edges in the CCW direction around the origin vertex * (Onext) and around the left face (Lnext). There is also a "next" * pointer for the global edge list (see below). * * The notation used for mesh navigation: * Sym = the mate of a half-edge (same edge, but opposite direction) * Onext = edge CCW around origin vertex (keep same origin) * Dnext = edge CCW around destination vertex (keep same dest) * Lnext = edge CCW around left face (dest becomes new origin) * Rnext = edge CCW around right face (origin becomes new dest) * * "prev" means to substitute CW for CCW in the definitions above. * * The mesh keeps global lists of all vertices, faces, and edges, * stored as doubly-linked circular lists with a dummy header node. * The mesh stores pointers to these dummy headers (vHead, fHead, eHead). * * The circular edge list is special; since half-edges always occur * in pairs (e and e->Sym), each half-edge stores a pointer in only * one direction. Starting at eHead and following the e->next pointers * will visit each *edge* once (ie. e or e->Sym, but not both). * e->Sym stores a pointer in the opposite direction, thus it is * always true that e->Sym->next->Sym->next == e. * * Each vertex has a pointer to next and previous vertices in the * circular list, and a pointer to a half-edge with this vertex as * the origin (NULL if this is the dummy header). There is also a * field "data" for client data. * * Each face has a pointer to the next and previous faces in the * circular list, and a pointer to a half-edge with this face as * the left face (NULL if this is the dummy header). There is also * a field "data" for client data. * * Note that what we call a "face" is really a loop; faces may consist * of more than one loop (ie. not simply connected), but there is no * record of this in the data structure. The mesh may consist of * several disconnected regions, so it may not be possible to visit * the entire mesh by starting at a half-edge and traversing the edge * structure. * * The mesh does NOT support isolated vertices; a vertex is deleted along * with its last edge. Similarly when two faces are merged, one of the * faces is deleted (see __gl_meshDelete below). For mesh operations, * all face (loop) and vertex pointers must not be NULL. However, once * mesh manipulation is finished, __gl_MeshZapFace can be used to delete * faces of the mesh, one at a time.

The basic mesh operations are MakeEdge, * Splice, and Delete. All the other edge operations can be implemented * in terms of these. The other operations are provided for convenience * and/or efficiency. * * When a face is split or a vertex is added, they are inserted into the * global list *before* the existing vertex or face (ie. e->Org or e->Lface). * This makes it easier to process all vertices or faces in the global lists * without worrying about processing the same data twice. As a convenience, * when a face is split, the "inside" flag is copied from the old face. * Other internal data (v->data, v->activeRegion, f->data, f->marked, * f->trail, e->winding) is set to zero. * * ********************** Basic Edge Operations ************************** * * __gl_meshMakeEdge( mesh ) creates one edge, two vertices, and a loop. * The loop (face) consists of the two new half-edges. * * __gl_meshSplice( eOrg, eDst ) is the basic operation for changing the * mesh connectivity and topology. It changes the mesh so that * eOrg->Onext <- OLD( eDst->Onext ) * eDst->Onext <- OLD( eOrg->Onext ) * where OLD(...) means the value before the meshSplice operation. * * This can have two effects on the vertex structure: * - if eOrg->Org != eDst->Org, the two vertices are merged together * - if eOrg->Org == eDst->Org, the origin is split into two vertices * In both cases, eDst->Org is changed and eOrg->Org is untouched. * * Similarly (and independently) for the face structure, * - if eOrg->Lface == eDst->Lface, one loop is split into two * - if eOrg->Lface != eDst->Lface, two distinct loops are joined into one * In both cases, eDst->Lface is changed and eOrg->Lface is unaffected. * * __gl_meshDelete( eDel ) removes the edge eDel. There are several cases: * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop * eDel->Lface is deleted. Otherwise, we are splitting one loop into two; * the newly created loop will contain eDel->Dst. If the deletion of eDel * would create isolated vertices, those are deleted as well. * * ********************** Other Edge Operations ************************** * * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex. * eOrg and eNew will have the same left face. * * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew, * such that eNew == eOrg->Lnext. The new vertex is eOrg->Dst == eNew->Org. * eOrg and eNew will have the same left face. * * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst * to eDst->Org, and returns the corresponding half-edge eNew. * If eOrg->Lface == eDst->Lface, this splits one loop into two, * and the newly created loop is eNew->Lface. Otherwise, two disjoint * loops are merged into one, and the loop eDst->Lface is destroyed. * * ************************ Other Operations ***************************** * * __gl_meshNewMesh() creates a new mesh with no edges, no vertices, * and no loops (what we usually call a "face"). * * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in * both meshes, and returns the new mesh (the old meshes are destroyed). * * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh. * * __gl_meshZapFace( fZap ) destroys a face and removes it from the * global face list. All edges of fZap will have a NULL pointer as their * left face. Any edges which also have a NULL pointer as their right face * are deleted entirely (along with any isolated vertices this produces). * An entire mesh can be deleted by zapping its faces, one at a time, * in any order. Zapped faces cannot be used in further mesh operations! * * __gl_meshCheckMesh( mesh ) checks a mesh for self-consistency. */ GLUhalfEdge *__gl_meshMakeEdge( GLUmesh *mesh ); int __gl_meshSplice( GLUhalfEdge *eOrg, GLUhalfEdge *eDst ); int __gl_meshDelete( GLUhalfEdge *eDel ); GLUhalfEdge *__gl_meshAddEdgeVertex( GLUhalfEdge *eOrg ); GLUhalfEdge *__gl_meshSplitEdge( GLUhalfEdge *eOrg ); GLUhalfEdge *__gl_meshConnect( GLUhalfEdge *eOrg, GLUhalfEdge *eDst ); GLUmesh *__gl_meshNewMesh( void ); GLUmesh *__gl_meshUnion( GLUmesh *mesh1, GLUmesh *mesh2 ); void __gl_meshDeleteMesh( GLUmesh *mesh ); void __gl_meshZapFace( GLUface *fZap ); #ifdef NDEBUG #define __gl_meshCheckMesh( mesh ) #else void __gl_meshCheckMesh( GLUmesh *mesh ); #endif #endif muffin-5.2.1/cogl/cogl-path/cogl-path-types.h0000664000175000017500000000610714211404421021133 0ustar jpeisachjpeisach/* * Cogl * * A Low Level GPU Graphics and Utilities API * * Copyright (C) 2008,2009,2013 Intel Corporation. * * Permission is hereby granted, free of charge, to any person * obtaining a copy of this software and associated documentation * files (the "Software"), to deal in the Software without * restriction, including without limitation the rights to use, copy, * modify, merge, publish, distribute, sublicense, and/or sell copies * of the Software, and to permit persons to whom the Software is * furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be * included in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND * NONINFRINGEMENT.

The values could be passed to Cogl only when * manipulation is necessary. * * * * Disadvantages: * * * Aliasing: it's possible to represent some rotations with multiple * different heading, pitch and roll rotations. * * * They can suffer from a problem called Gimbal Lock. A good * explanation of this can be seen on wikipedia here: * http://en.wikipedia.org/wiki/Gimbal_lock but basically two * of the axis of rotation may become aligned and so you loose a * degree of freedom. For example a pitch of +-90° would mean that * heading and bank rotate around the same axis. * * * If you use euler angles to orient something in 3D space and try to * transition between orientations by interpolating the component * angles you probably wont get the transitions you expect as they may * not follow the shortest path between the two orientations. * * * There's no standard to what order the component axis rotations are * applied. The most common convention seems to be what we do in Cogl * with heading (y-axis), pitch (x-axis) and then roll (z-axis), but * other software might apply x-axis, y-axis then z-axis or any other * order so you need to consider this if you are accepting euler * rotations from some other software. Other software may also use * slightly different aeronautical terms, such as "yaw" instead of * "heading" or "bank" instead of "roll". * * * * To minimize the aliasing issue we may refer to "Canonical Euler" * angles where heading and roll are restricted to +- 180° and pitch is * restricted to +- 90°. If pitch is +- 90° bank is set to 0°. * * Quaternions don't suffer from Gimbal Lock and they can be nicely * interpolated between, their disadvantage is that they don't have an * intuitive representation. * * A common practice is to accept angles in the intuitive Euler form * and convert them to quaternions internally to avoid Gimbal Lock and * handle interpolations.

This is to * help applications control the lifetime a context without us needing to * introduce special api to handle the breakup of internal circular * references due to internal resources and caches associated with the * context. * * One a context has been destroyed then all directly or indirectly * dependant resources will be in an inconsistent state and should not * be manipulated or queried in any way. * * For applications that rely on the operating system to clean up * resources this policy shouldn't affect them, but for applications * that need to carefully destroy and re-create Cogl contexts multiple * times throughout their lifetime (such as Android applications) they * should be careful to destroy all context dependant resources, such as * framebuffers or textures etc before unrefing and destroying the * context. */ #define COGL_CONTEXT(OBJECT) ((CoglContext *)OBJECT) /** * cogl_context_get_gtype: * * Returns: a #GType that can be used with the GLib type system. */ GType cogl_context_get_gtype (void); /** * cogl_context_new: (constructor) * @display: (allow-none): A #CoglDisplay pointer * @error: A CoglError return location. * * Creates a new #CoglContext which acts as an application sandbox * for any state objects that are allocated. * * Return value: (transfer full): A newly allocated #CoglContext * Since: 1.8 * Stability: unstable */ CoglContext * cogl_context_new (CoglDisplay *display, CoglError **error); /** * cogl_context_get_display: * @context: A #CoglContext pointer * * Retrieves the #CoglDisplay that is internally associated with the * given @context.

There is no * the concept of stack frames to allow partial rewinds. * * For example; we plan to use this in our tesselator which has to * allocate lots of small vertex, edge and face structures because * when tesselation has been finished we just want to free the whole * lot in one go. * * * Authors: * Robert Bragg */ #ifdef HAVE_CONFIG_H #include "cogl-config.h" #endif #include "cogl-memory-stack-private.h" #include "cogl-list.h" #include #include typedef struct _CoglMemorySubStack { CoglList link; size_t bytes; uint8_t *data; } CoglMemorySubStack; struct _CoglMemoryStack { CoglList sub_stacks; CoglMemorySubStack *sub_stack; size_t sub_stack_offset; }; static CoglMemorySubStack * _cogl_memory_sub_stack_alloc (size_t bytes) { CoglMemorySubStack *sub_stack = g_slice_new (CoglMemorySubStack); sub_stack->bytes = bytes; sub_stack->data = malloc (bytes); return sub_stack; } static void _cogl_memory_stack_add_sub_stack (CoglMemoryStack *stack, size_t sub_stack_bytes) { CoglMemorySubStack *sub_stack = _cogl_memory_sub_stack_alloc (sub_stack_bytes); _cogl_list_insert (stack->sub_stacks.prev, &sub_stack->link); stack->sub_stack = sub_stack; stack->sub_stack_offset = 0; } CoglMemoryStack * _cogl_memory_stack_new (size_t initial_size_bytes) { CoglMemoryStack *stack = g_slice_new0 (CoglMemoryStack); _cogl_list_init (&stack->sub_stacks); _cogl_memory_stack_add_sub_stack (stack, initial_size_bytes); return stack; } void * _cogl_memory_stack_alloc (CoglMemoryStack *stack, size_t bytes) { CoglMemorySubStack *sub_stack; void *ret; sub_stack = stack->sub_stack; if (G_LIKELY (sub_stack->bytes - stack->sub_stack_offset >= bytes)) { ret = sub_stack->data + stack->sub_stack_offset; stack->sub_stack_offset += bytes; return ret; } /* If the stack has been rewound and then a large initial allocation * is made then we may need to skip over one or more of the * sub-stacks that are too small for the requested allocation * size... */ for (_cogl_list_set_iterator (sub_stack->link.next, sub_stack, link); &sub_stack->link != &stack->sub_stacks; _cogl_list_set_iterator (sub_stack->link.next, sub_stack, link)) { if (sub_stack->bytes >= bytes) { ret = sub_stack->data; stack->sub_stack = sub_stack; stack->sub_stack_offset = bytes; return ret; } } /* Finally if we couldn't find a free sub-stack with enough space * for the requested allocation we allocate another sub-stack that's * twice as big as the last sub-stack or twice as big as the * requested allocation if that's bigger. */ sub_stack = _cogl_container_of (stack->sub_stacks.prev, CoglMemorySubStack, link); _cogl_memory_stack_add_sub_stack (stack, MAX (sub_stack->bytes, bytes) * 2); sub_stack = _cogl_container_of (stack->sub_stacks.prev, CoglMemorySubStack, link); stack->sub_stack_offset += bytes; return sub_stack->data; } void _cogl_memory_stack_rewind (CoglMemoryStack *stack) { stack->sub_stack = _cogl_container_of (stack->sub_stacks.next, CoglMemorySubStack, link); stack->sub_stack_offset = 0; } static void _cogl_memory_sub_stack_free (CoglMemorySubStack *sub_stack) { free (sub_stack->data); g_slice_free (CoglMemorySubStack, sub_stack); } void _cogl_memory_stack_free (CoglMemoryStack *stack) { while (!_cogl_list_empty (&stack->sub_stacks)) { CoglMemorySubStack *sub_stack = _cogl_container_of (stack->sub_stacks.next, CoglMemorySubStack, link); _cogl_list_remove (&sub_stack->link); _cogl_memory_sub_stack_free (sub_stack); } g_slice_free (CoglMemoryStack, stack); } muffin-5.2.1/cogl/cogl/cogl-memory-stack-private.h0000664000175000017500000000312314211404421022161 0ustar jpeisachjpeisach/* * Cogl * * A Low Level GPU Graphics and Utilities API * * Copyright (C) 2011 Intel Corporation. * * Permission is hereby granted, free of charge, to any person * obtaining a copy of this software and associated documentation * files (the "Software"), to deal in the Software without * restriction, including without limitation the rights to use, copy, * modify, merge, publish, distribute, sublicense, and/or sell copies * of the Software, and to permit persons to whom the Software is * furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be * included in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND * NONINFRINGEMENT.

Copying a pipeline creates an empty * diff and a child->parent relationship between the empty diff and * the source @pipeline, parent. * * Because of this internal graph design a single #CoglPipeline may * indirectly depend on a chain of ancestors to fully define all of * its properties. Because a node depends on its ancestors it normally * owns a reference to its parent to stop it from being freed. Also if * you try to modify a pipeline with children we internally use a * copy-on-write mechanism to ensure that you don't indirectly change * the properties those children. * * Weak pipelines avoid the use of copy-on-write to preserve the * integrity of weak dependants and instead weak dependants are * simply destroyed allowing the parent to be modified directly. Also * because weak pipelines don't own a reference to their parent they * won't stop the source @pipeline from being freed when the user * releases their reference on it. * * Because weak pipelines don't own a reference on their parent they * are the recommended mechanism for creating derived pipelines that you * want to cache as a private property of the original pipeline * because they won't result in a circular dependency. * * An example use case: * * Consider for example you are implementing a custom primitive that is * not compatible with certain source pipelines. To handle this you * implement a validation stage that given an arbitrary pipeline as * input will create a derived pipeline that is suitable for drawing * your primitive. * * Because you don't want to have to repeat this validation every time * the same incompatible pipeline is given as input you want to cache * the result as a private property of the original pipeline. If the * derived pipeline were created using cogl_pipeline_copy that would * create a circular dependency so the original pipeline can never be * freed. * * If you instead create a weak copy you won't stop the original pipeline * from being freed if it's no longer needed, and you will instead simply * be notified that your weak pipeline has been destroyed. * * This is the recommended coding pattern for validating an input * pipeline and caching a derived result: * |[ * static CoglUserDataKey _cogl_my_cache_key; * * typedef struct { * CoglPipeline *validated_source; * } MyValidatedMaterialCache; * * static void * destroy_cache_cb (CoglObject *object, void *user_data) * { * g_slice_free (MyValidatedMaterialCache, user_data); * } * * static void * invalidate_cache_cb (CoglPipeline *destroyed, void *user_data) * { * MyValidatedMaterialCache *cache = user_data; * cogl_object_unref (cache->validated_source); * cache->validated_source = NULL; * } * * static CoglPipeline * * get_validated_pipeline (CoglPipeline *source) * { * MyValidatedMaterialCache *cache = * cogl_object_get_user_data (COGL_OBJECT (source), * &_cogl_my_cache_key); * if (G_UNLIKELY (cache == NULL)) * { * cache = g_slice_new (MyValidatedMaterialCache); * cogl_object_set_user_data (COGL_OBJECT (source), * &_cogl_my_cache_key, * cache, destroy_cache_cb); * cache->validated_source = source; * } * * if (G_UNLIKELY (cache->validated_source == NULL)) * { * cache->validated_source = source; * * / * Start validating source... * / * * / * If you find you need to change something... * / * if (cache->validated_source == source) * cache->validated_source = * cogl_pipeline_weak_copy (source, * invalidate_cache_cb, * cache); * * / * Modify cache->validated_source * / * } * * return cache->validated_source; * } * ]| */ CoglPipeline * _cogl_pipeline_weak_copy (CoglPipeline *pipeline, CoglPipelineDestroyCallback callback, void *user_data); void _cogl_pipeline_set_progend (CoglPipeline *pipeline, int progend); CoglPipeline * _cogl_pipeline_get_parent (CoglPipeline *pipeline); void _cogl_pipeline_get_colorubv (CoglPipeline *pipeline, uint8_t *color); /* XXX: At some point it could be good for this to accept a mask of * the state groups we are interested in comparing since we can * probably use that information in a number situations to reduce * the work we do. */ unsigned long _cogl_pipeline_compare_differences (CoglPipeline *pipeline0, CoglPipeline *pipeline1); CoglBool _cogl_pipeline_equal (CoglPipeline *pipeline0, CoglPipeline *pipeline1, unsigned int differences, unsigned long layer_differences, CoglPipelineEvalFlags flags); unsigned int _cogl_pipeline_hash (CoglPipeline *pipeline, unsigned int differences, unsigned long layer_differences, CoglPipelineEvalFlags flags); /* Makes a copy of the given pipeline that is a child of the root * pipeline rather than a child of the source pipeline.

These low-level textures * are the only ones that a GPU really understands but because * applications often want more high-level texture abstractions * (such as storing multiple textures inside one larger "atlas" * texture) it's desirable to be able to deal with these * using a common interface. * * For example the GPU is not able to automatically handle repeating a * texture that is part of a larger atlas texture but if you use * %COGL_PIPELINE_WRAP_MODE_REPEAT with an atlas texture when drawing * with cogl_rectangle() you should see that it "Just Works™" - at * least if you don't use multi-texturing. The reason this works is * because cogl_rectangle() internally understands the #CoglMetaTexture * interface and is able to manually resolve the low-level textures * using this interface and by making multiple draw calls it can * emulate the texture repeat modes. * * Cogl doesn't aim to pretend that meta-textures are just like real * textures because it would get extremely complex to try and emulate * low-level GPU semantics transparently for these textures. The low * level drawing APIs of Cogl, such as cogl_primitive_draw() don't * actually know anything about the #CoglMetaTexture interface and its * the developer's responsibility to resolve all textures referenced * by a #CoglPipeline to low-level textures before drawing. * * If you want to develop custom primitive APIs like * cogl_framebuffer_draw_rectangle() and you want to support drawing * with #CoglAtlasTextures or #CoglSubTextures for * example, then you will need to use this #CoglMetaTexture interface * to be able to resolve high-level textures into low-level textures * before drawing with Cogl's low-level drawing APIs such as * cogl_primitive_draw(). * * Most developers won't need to use this interface directly * but still it is worth understanding the distinction between * low-level and meta textures because you may find other references * in the documentation that detail limitations of using * meta-textures. */ #if defined(__COGL_H_INSIDE__) && !defined(COGL_ENABLE_MUFFIN_API) && \ !defined(COGL_GIR_SCANNING) /* For the public C api we typedef interface types as void to avoid needing * lots of casting in code and instead we will rely on runtime type checking * for these objects. */ typedef void CoglMetaTexture; #else typedef struct _CoglMetaTexture CoglMetaTexture; #define COGL_META_TEXTURE(X) ((CoglMetaTexture *)X) #endif /** * CoglMetaTextureCallback: * @sub_texture: A low-level #CoglTexture making up part of a * #CoglMetaTexture. * @sub_texture_coords: A float 4-tuple ordered like * (tx1,ty1,tx2,ty2) defining what region of the * current @sub_texture maps to a sub-region of a * #CoglMetaTexture.

It would not be acceptable to simply require that * developers must query back the n_vertices of a buffer and then the * n_components, type and stride etc of each attribute since there * would be too many combinations to realistically handle. * * - In practice, some cases might be best solved with a higher level * EditableMesh API, (see futher below) but for many cases I think an * API like this might be appropriate: * * cogl_vertex_buffer_foreach_vertex (buffer_handle, * (AttributesBufferIteratorFunc)callback, * "gl_Vertex", "gl_Color", NULL); * static void callback (CoglVertexBufferVertex *vert) * { * GLfloat *pos = vert->attrib[0]; * GLubyte *color = vert->attrib[1]; * GLfloat *new_attrib = buf[vert->index]; * * new_attrib = pos*color; * } * * TODO * Think about a higher level Mesh API for building/modifying attribute buffers * - E.g. look at Blender for inspiration here. They can build a mesh from * "MVert", "MFace" and "MEdge" primitives. */ #ifdef HAVE_CONFIG_H #include "cogl-config.h" #endif #include #include #include #include "cogl-util.h" #include "cogl-context-private.h" #include "cogl-object-private.h" #include "cogl-vertex-buffer-private.h" #include "cogl-texture-private.h" #include "cogl-pipeline.h" #include "cogl-pipeline-private.h" #include "cogl-primitives.h" #include "cogl-framebuffer-private.h" #include "cogl-primitive-private.h" #include "cogl-journal-private.h" #include "cogl1-context.h" #include "cogl-vertex-buffer.h" #define PAD_FOR_ALIGNMENT(VAR, TYPE_SIZE) \ (VAR = TYPE_SIZE + ((VAR - 1) & ~(TYPE_SIZE - 1))) static void _cogl_vertex_buffer_free (CoglVertexBuffer *buffer); static void _cogl_vertex_buffer_indices_free (CoglVertexBufferIndices *buffer_indices); static CoglUserDataKey _cogl_vertex_buffer_pipeline_priv_key; COGL_HANDLE_DEFINE (VertexBuffer, vertex_buffer); COGL_OBJECT_DEFINE_DEPRECATED_REF_COUNTING (vertex_buffer); COGL_HANDLE_DEFINE (VertexBufferIndices, vertex_buffer_indices); CoglHandle cogl_vertex_buffer_new (unsigned int n_vertices) { CoglVertexBuffer *buffer = g_slice_alloc (sizeof (CoglVertexBuffer)); buffer->n_vertices = n_vertices; buffer->submitted_vbos = NULL; buffer->new_attributes = NULL; buffer->primitive = cogl_primitive_new (COGL_VERTICES_MODE_TRIANGLES, n_vertices, NULL); /* return COGL_INVALID_HANDLE; */ return _cogl_vertex_buffer_handle_new (buffer); } unsigned int cogl_vertex_buffer_get_n_vertices (CoglHandle handle) { CoglVertexBuffer *buffer; if (!cogl_is_vertex_buffer (handle)) return 0; buffer = handle; return buffer->n_vertices; } /* There are a number of standard OpenGL attributes that we deal with * specially.

If the source * code is ARBfp, it must begin with the string “!!ARBfp1.0”. The * application should check for the %COGL_FEATURE_SHADERS_GLSL or * %COGL_FEATURE_SHADERS_ARBFP features before using shaders. * * When using GLSL Cogl provides replacement names for most of the * builtin varyings and uniforms. It is recommended to use these names * wherever possible to increase portability between OpenGL 2.0 and * GLES 2.0. GLES 2.0 does not have most of the builtins under their * original names so they will only work with the Cogl names. * * For use in all GLSL shaders, the Cogl builtins are as follows: * * * * * uniform mat4 * cogl_modelview_matrix * * The current modelview matrix. This is equivalent to * #gl_ModelViewMatrix. * * * * uniform mat4 * cogl_projection_matrix * * The current projection matrix. This is equivalent to * #gl_ProjectionMatrix. * * * * uniform mat4 * cogl_modelview_projection_matrix * * The combined modelview and projection matrix. A vertex shader * would typically use this to transform the incoming vertex * position. The separate modelview and projection matrices are * usually only needed for lighting calculations. This is * equivalent to #gl_ModelViewProjectionMatrix. * * * * uniform mat4 * cogl_texture_matrix[] * * An array of matrices for transforming the texture * coordinates. This is equivalent to #gl_TextureMatrix. * * * * * * In a vertex shader, the following are also available: * * * * * attribute vec4 * cogl_position_in * * The incoming vertex position. This is equivalent to #gl_Vertex. * * * * attribute vec4 * cogl_color_in * * The incoming vertex color. This is equivalent to #gl_Color. * * * * attribute vec4 * cogl_tex_coord_in * * The texture coordinate for the first texture unit. This is * equivalent to #gl_MultiTexCoord0. * * * * attribute vec4 * cogl_tex_coord0_in * * The texture coordinate for the first texture unit. This is * equivalent to #gl_MultiTexCoord0. There is also * #cogl_tex_coord1_in and so on. * * * * attribute vec3 * cogl_normal_in * * The normal of the vertex. This is equivalent to #gl_Normal. * * * * vec4 * cogl_position_out * * The calculated position of the vertex. This must be written to * in all vertex shaders. This is equivalent to #gl_Position. * * * * float * cogl_point_size_out * * The calculated size of a point. This is equivalent to #gl_PointSize. * * * * varying vec4 * cogl_color_out * * The calculated color of a vertex. This is equivalent to #gl_FrontColor. * * * * varying vec4 * cogl_tex_coord_out[] * * An array of calculated texture coordinates for a vertex. This is * equivalent to #gl_TexCoord. * * * * * * In a fragment shader, the following are also available: * * * * * varying vec4 cogl_color_in * * The calculated color of a vertex. This is equivalent to #gl_FrontColor. * * * * varying vec4 * cogl_tex_coord_in[] * * An array of calculated texture coordinates for a vertex. This is * equivalent to #gl_TexCoord. * * * * vec4 cogl_color_out * * The final calculated color of the fragment. All fragment shaders * must write to this variable.

This is equivalent to #gl_FragDepth. * * * * bool cogl_front_facing * * A readonly variable that will be true if the current primitive * is front facing. This can be used to implement two-sided * coloring algorithms.

GLSL is a programming language supported * by OpenGL on programmable hardware to provide a more flexible * description of what should be rendered. A description of GLSL * itself is outside the scope of this documentation but any good * OpenGL book should help to describe it. * * Unlike in OpenGL, when using GLSL with Cogl it is possible to write * short snippets to replace small sections of the pipeline instead of * having to replace the whole of either the vertex or fragment * pipelines. Of course it is also possible to replace the whole of * the pipeline if needed. * * Each snippet is a standalone chunk of code which would attach to * the pipeline at a particular point. The code is split into four * separate strings (all of which are optional): * * * * declarations * * The code in this string will be inserted outside of any function in * the global scope of the shader. This can be used to declare * uniforms, attributes, varyings and functions to be used by the * snippet. * * * * pre * * The code in this string will be inserted before the hook point. * * * * post * * The code in this string will be inserted after the hook point. This * can be used to modify the results of the builtin generated code for * that hook point. * * * * replace * * If present the code in this string will replace the generated code * for the hook point. * * * * * All of the strings apart from the declarations string of a pipeline * are generated in a single function so they can share variables * declared from one string in another. The scope of the code is * limited to each snippet so local variables declared in the snippet * will not collide with variables declared in another * snippet. However, code in the 'declarations' string is global to * the shader so it is the application's responsibility to ensure that * variables declared here will not collide with those from other * snippets. * * The snippets can be added to a pipeline with * cogl_pipeline_add_snippet() or * cogl_pipeline_add_layer_snippet(). Which function to use depends on * which hook the snippet is targetting. The snippets are all * generated in the order they are added to the pipeline. That is, the * post strings are executed in the order they are added to the * pipeline and the pre strings are executed in reverse order. If any * replace strings are given for a snippet then any other snippets * with the same hook added before that snippet will be ignored. The * different hooks are documented under #CoglSnippetHook. * * For portability with GLES2, it is recommended not to use the GLSL * builtin names such as gl_FragColor. Instead there are replacement * names under the cogl_* namespace which can be used instead. These * are: * * * * uniform mat4 * cogl_modelview_matrix * * The current modelview matrix. This is equivalent to * #gl_ModelViewMatrix. * * * * uniform mat4 * cogl_projection_matrix * * The current projection matrix. This is equivalent to * #gl_ProjectionMatrix. * * * * uniform mat4 * cogl_modelview_projection_matrix * * The combined modelview and projection matrix. A vertex shader * would typically use this to transform the incoming vertex * position. The separate modelview and projection matrices are * usually only needed for lighting calculations. This is * equivalent to #gl_ModelViewProjectionMatrix. * * * * uniform mat4 * cogl_texture_matrix[] * * An array of matrices for transforming the texture * coordinates. This is equivalent to #gl_TextureMatrix. * * * * * In a vertex shader, the following are also available: * * * * attribute vec4 * cogl_position_in * * The incoming vertex position. This is equivalent to #gl_Vertex. * * * * attribute vec4 * cogl_color_in * * The incoming vertex color. This is equivalent to #gl_Color. * * * * attribute vec4 * cogl_tex_coord_in * * The texture coordinate for layer 0. This is an alternative name * for #cogl_tex_coord0_in. * * * * attribute vec4 * cogl_tex_coord0_in * * The texture coordinate for the layer 0. This is equivalent to * #gl_MultiTexCoord0. There will also be #cogl_tex_coord1_in and * so on if more layers are added to the pipeline. * * * * attribute vec3 * cogl_normal_in * * The normal of the vertex. This is equivalent to #gl_Normal. * * * * vec4 * cogl_position_out * * The calculated position of the vertex. This must be written to * in all vertex shaders. This is equivalent to #gl_Position. * * * * float * cogl_point_size_in * * The incoming point size from the cogl_point_size_in attribute. * This is only available if * cogl_pipeline_set_per_vertex_point_size() is set on the * pipeline. * * * * float * cogl_point_size_out * * The calculated size of a point. This is equivalent to #gl_PointSize. * * * * varying vec4 * cogl_color_out * * The calculated color of a vertex. This is equivalent to #gl_FrontColor. * * * * varying vec4 * cogl_tex_coord0_out * * The calculated texture coordinate for layer 0 of the pipeline. * This is equivalent to #gl_TexCoord[0]. There will also be * #cogl_tex_coord1_out and so on if more layers are added to the * pipeline. In the fragment shader, this varying is called * #cogl_tex_coord0_in. * * * * * In a fragment shader, the following are also available: * * * * varying vec4 cogl_color_in * * The calculated color of a vertex. This is equivalent to #gl_FrontColor. * * * * varying vec4 * cogl_tex_coord0_in * * The texture coordinate for layer 0. This is equivalent to * #gl_TexCoord[0]. There will also be #cogl_tex_coord1_in and so * on if more layers are added to the pipeline. * * * * vec4 cogl_color_out * * The final calculated color of the fragment. All fragment shaders * must write to this variable. This is equivalent to * #gl_FrontColor. * * * * float cogl_depth_out * * An optional output variable specifying the depth value to use * for this fragment. This is equivalent to #gl_FragDepth. * * * * bool cogl_front_facing * * A readonly variable that will be true if the current primitive * is front facing. This can be used to implement two-sided * coloring algorithms. This is equivalent to #gl_FrontFacing. * * * * vec2 cogl_point_coord * * When rendering points, this will contain a vec2 which represents * the position within the point of the current fragment. * vec2(0.0,0.0) will be the topleft of the point and vec2(1.0,1.0) * will be the bottom right. Note that there is currently a bug in * Cogl where when rendering to an offscreen buffer these * coordinates will be upside-down. The value is undefined when not * rendering points. This builtin can only be used if the * %COGL_FEATURE_ID_POINT_SPRITE feature is available. * * * * * Here is an example of using a snippet to add a desaturate effect to the * generated color on a pipeline. * * * CoglPipeline *pipeline = cogl_pipeline_new (); * * /* Set up the pipeline here, ie by adding a texture or other * layers */ * * /* Create the snippet.

Use this to declare any uniforms, * attributes or functions that the snippet requires. * * * The ‘pre’ string in @snippet will be inserted just before * calculating the point size. * * * The ‘replace’ string in @snippet will be used instead of the * generated point size calculation if it is present. * * * The ‘post’ string in @snippet will be inserted after the * standard point size calculation is done. This can be used to modify * cogl_point_size_out in addition to the default processing. * * * * * %COGL_SNIPPET_HOOK_FRAGMENT * * * Adds a shader snippet that will hook on to the fragment processing * stage of the pipeline. This gives a chance for the application to * modify the fragment color generated by the shader. Typically the * snippet will modify cogl_color_out. * * * The ‘declarations’ string in @snippet will be inserted in the * global scope of the shader. Use this to declare any uniforms, * attributes or functions that the snippet requires. * * * The ‘pre’ string in @snippet will be inserted at the top of the * main() function before any fragment processing is done. * * * The ‘replace’ string in @snippet will be used instead of the * generated fragment processing if it is present. This can be used if * the application wants to provide a complete fragment shader and * doesn't need the generated output from Cogl. * * * The ‘post’ string in @snippet will be inserted after all of the * standard fragment processing is done. At this point the generated * value for the rest of the pipeline state will already be in * cogl_color_out so the application can modify the result by altering * this variable. * * * * * %COGL_SNIPPET_HOOK_TEXTURE_COORD_TRANSFORM * * * Adds a shader snippet that will hook on to the texture coordinate * transformation of a particular layer. This can be used to replace * the processing for a layer or to modify the results. * * * Within the snippet code for this hook there are two extra * variables. The first is a mat4 called cogl_matrix which represents * the user matrix for this layer. The second is called cogl_tex_coord * and represents the incoming and outgoing texture coordinate. On * entry to the hook, cogl_tex_coord contains the value of the * corresponding texture coordinate attribute for this layer. The hook * is expected to modify this variable. The output will be passed as a * varying to the fragment processing stage. The default code will * just multiply cogl_matrix by cogl_tex_coord and store the result in * cogl_tex_coord. * * * The ‘declarations’ string in @snippet will be inserted in the * global scope of the shader. Use this to declare any uniforms, * attributes or functions that the snippet requires. * * * The ‘pre’ string in @snippet will be inserted just before the * fragment processing for this layer. At this point cogl_tex_coord * still contains the value of the texture coordinate attribute. * * * If a ‘replace’ string is given then this will be used instead of * the default fragment processing for this layer. The snippet can * modify cogl_tex_coord or leave it as is to apply no transformation. * * * The ‘post’ string in @snippet will be inserted just after the * transformation. At this point cogl_tex_coord will contain the * results of the transformation but it can be further modified by the * snippet. * * * * * %COGL_SNIPPET_HOOK_LAYER_FRAGMENT * * * Adds a shader snippet that will hook on to the fragment processing * of a particular layer. This can be used to replace the processing * for a layer or to modify the results. * * * Within the snippet code for this hook there is an extra vec4 * variable called ‘cogl_layer’. This contains the resulting color * that will be used for the layer. This can be modified in the ‘post’ * section or it the default processing can be replaced entirely using * the ‘replace’ section. * * * The ‘declarations’ string in @snippet will be inserted in the * global scope of the shader. Use this to declare any uniforms, * attributes or functions that the snippet requires. * * * The ‘pre’ string in @snippet will be inserted just before the * fragment processing for this layer. * * * If a ‘replace’ string is given then this will be used instead of * the default fragment processing for this layer. The snippet must write to * the ‘cogl_layer’ variable in that case. * * * The ‘post’ string in @snippet will be inserted just after the * fragment processing for the layer. The results can be modified by changing * the value of the ‘cogl_layer’ variable. * * * * * %COGL_SNIPPET_HOOK_TEXTURE_LOOKUP * * * Adds a shader snippet that will hook on to the texture lookup part * of a given layer. This gives a chance for the application to modify * the coordinates that will be used for the texture lookup or to * alter the returned texel. * * * Within the snippet code for this hook there are three extra * variables available. ‘cogl_sampler’ is a sampler object * representing the sampler for the layer where the snippet is * attached. ‘cogl_tex_coord’ is a vec4 which contains the texture * coordinates that will be used for the texture lookup. This can be * modified. ‘cogl_texel’ will contain the result of the texture * lookup. This can also be modified. * * * The ‘declarations’ string in @snippet will be inserted in the * global scope of the shader. Use this to declare any uniforms, * attributes or functions that the snippet requires. * * * The ‘pre’ string in @snippet will be inserted at the top of the * main() function before any fragment processing is done. This is a * good place to modify the cogl_tex_coord variable. * * * If a ‘replace’ string is given then this will be used instead of a * the default texture lookup. The snippet would typically use its own * sampler in this case. * * * The ‘post’ string in @snippet will be inserted after texture lookup * has been preformed. Here the snippet can modify the cogl_texel * variable to alter the returned texel. * * * * * * Since: 1.10 * Stability: Unstable */ typedef enum { /* Per pipeline vertex hooks */ COGL_SNIPPET_HOOK_VERTEX = 0, COGL_SNIPPET_HOOK_VERTEX_TRANSFORM, COGL_SNIPPET_HOOK_VERTEX_GLOBALS, COGL_SNIPPET_HOOK_POINT_SIZE, /* Per pipeline fragment hooks */ COGL_SNIPPET_HOOK_FRAGMENT = 2048, COGL_SNIPPET_HOOK_FRAGMENT_GLOBALS, /* Per layer vertex hooks */ COGL_SNIPPET_HOOK_TEXTURE_COORD_TRANSFORM = 4096, /* Per layer fragment hooks */ COGL_SNIPPET_HOOK_LAYER_FRAGMENT = 6144, COGL_SNIPPET_HOOK_TEXTURE_LOOKUP } CoglSnippetHook; /** * cogl_snippet_new: * @hook: The point in the pipeline that this snippet will wrap around * or replace. * @declarations: The source code for the declarations for this * snippet or %NULL.

Also it may have something to do with the Meta key on UNIX keyboards. The first release of Metacity was version 2.3. Metacity has no need for your petty hangups about version numbers.

COMPILING MUFFIN === You need GTK+ 2.2. For startup notification to work you need libstartup-notification at http://www.freedesktop.org/software/startup-notification/ or on the GNOME ftp site. You need Clutter 1.0. You need gobject-introspection 0.6.3. REPORTING BUGS AND SUBMITTING PATCHES === Report new bugs on http://bugzilla.gnome.org. Please check for duplicates, *especially* if you are reporting a feature request. Please do *not* add "me too!" or "yes I really want this!" comments to feature requests in bugzilla. Please read http://pobox.com/~hp/features.html prior to adding any kind of flame about missing features or misfeatures. Feel free to send patches too; Metacity is relatively small and simple, so if you find a bug or want to add a feature it should be pretty easy. Send me mail, or put the patch in bugzilla. See the HACKING file for some notes on hacking Muffin. MUFFIN FEATURES === - Uses GTK+ 2.0 for drawing window frames. This means colors, fonts, etc. come from GTK+ theme. - Does not expose the concept of "window manager" to the user. Some of the features in the GNOME control panel and other parts of the desktop happen to be implemented in metacity, such as changing your window border theme, or changing your window navigation shortcuts, but the user doesn't need to know this. - Includes only the window manager; does not try to be a desktop environment. The pager, configuration, etc. are all separate and modular. The "libwnck" library (which I also wrote) is available for writing metacity extensions, pagers, and so on. (But libwnck isn't metacity specific, or GNOME-dependent; it requires only GTK, and should work with KWin, fvwm2, and other EWMH-compliant WMs.) - Has a simple theme system and a couple of extra themes come with it. Change themes via gsettings: gsettings set org.cinnamon.desktop.wm.preferences theme Crux gsettings set org.cinnamon.desktop.wm.preferences theme Gorilla gsettings set org.cinnamon.desktop.wm.preferences theme Atlanta gsettings set org.cinnamon.desktop.wm.preferences theme Bright See theme-format.txt for docs on the theme format. Use metacity-theme-viewer to preview themes. - Change number of workspaces via gsettings: gsettings set org.cinnamon.desktop.wm.preferences num-workspaces 5 Can also change workspaces from GNOME 2 pager. - Change focus mode: gsettings set org.cinnamon.desktop.wm.preferences focus-mode mouse gsettings set org.cinnamon.desktop.wm.preferences focus-mode sloppy gsettings set org.cinnamon.desktop.wm.preferences focus-mode click - Global keybinding defaults include: Alt-Tab forward cycle window focus Alt-Shift-Tab backward cycle focus Alt-Ctrl-Tab forward cycle focus among panels Alt-Ctrl-Shift-Tab backward cycle focus among panels Alt-Escape cycle window focus without a popup thingy Ctrl-Alt-Left Arrow previous workspace Ctrl-Alt-Right Arrow next workspace Ctrl-Alt-D minimize/unminimize all, to show desktop Change keybindings for example: gsettings set org.cinnamon.desktop.wm.keybindings switch-to-workspace-1 '[F1]' Also try the GNOME keyboard shortcuts control panel. - Window keybindings: Alt-space window menu Mnemonics work in the menu. That is, Alt-space then underlined letter in the menu item works. Choose Move from menu, and arrow keys to move the window. While moving, hold down Control to move slower, and Shift to snap to edges. Choose Resize from menu, and nothing happens yet, but eventually I might implement something. Keybindings for things like maximize window, vertical maximize, etc. can be bound, but may not all exist by default. See metacity.schemas. - Window mouse bindings: Clicking anywhere on frame with button 1 will raise/focus window If you click a window control, such as the close button, then the control will activate on button release if you are still over it on release (as with most GUI toolkits) If you click and drag borders with button 1 it resizes the window If you click and drag the titlebar with button 1 it moves the window. If you click anywhere on the frame with button 2 it lowers the window. If you click anywhere on the frame with button 3 it shows the window menu. If you hold down Super (windows key) and click inside a window, it will move the window (buttons 1 and 2) or show menu (button 3). Or you can configure a different modifier for this. If you pick up a window with button 1 and then switch workspaces the window will come with you to the new workspace, this is a feature copied from Enlightenment. If you hold down Shift while moving a window, the window snaps to edges of other windows and the screen. - Session management: Muffin connects to the session manager and will set itself up to be respawned. It theoretically restores sizes/positions/workspace for session-aware applications. - Muffin implements much of the EWMH window manager specification from freedesktop.org, as well as the older ICCCM. Please refer to the COMPLIANCE file for information on muffin compliance with these standards. - Uses Pango to render text, so has cool i18n capabilities. Supports UTF-8 window titles and such. - There are simple animations for actions such as minimization, to help users see what is happening. Should probably have a few more of these and make them nicer. - if you have the proper X setup, set the GDK_USE_XFT=1 environment variable to get antialiased window titles. - considers the panel when placing windows and maximizing them. - handles the window manager selection from the ICCCM. Will exit if another WM claims it, and can claim it from another WM if you pass the --replace argument. So if you're running another ICCCM-compliant WM, you can run "muffin --replace" to replace it with Metacity. - does basic colormap handling - and much more! well, maybe not a lot more. HOW TO ADD EXTERNAL FEATURES === You can write a muffin "plugin" such as a pager, window list, icon box, task menu, or even things like "window matching" using the Extended Window Manager Hints. See http://www.freedesktop.org for the EWMH specification. An easy-to-use library called "libwnck" is available that uses the EWMH and is specifically designed for writing WM accessories. You might be interested in existing accessories such as "Devil's Pie" by Ross Burton, which add features to Muffin (or other EWMH-compliant WMs). MUFFIN BUGS, NON-FEATURES, AND CAVEATS === See bugzilla: http://bugzilla.gnome.org/query.cgi FAQ === Q: Will you add my feature? A: If it makes sense to turn on unconditionally, or is genuinely a harmless preference that I would not be embarrassed to put in a simple, uncluttered, user-friendly configuration dialog. If the only rationale for your feature is that other window managers have it, or that you are personally used to it, or something like that, then I will not be impressed. Metacity is firmly in the "choose good defaults" camp rather than the "offer 6 equally broken ways to do it, and let the user pick one" camp. This is part of a "no crackrock" policy, despite some exceptions I'm mildly embarrassed about. For example, multiple workspaces probably constitute crackrock, they confuse most users and really are not that useful if you have a decent tasklist and so on. But I am too used to them to turn them off. Or alternatively iconification/tasklist is crack, and workspaces/pager are good. But having both is certainly a bit wrong. Sloppy focus is probably crackrock too. But don't think unlimited crack is OK just because I slipped up a little. No slippery slope here. Don't let this discourage patches and fixes - I love those. ;-) Just be prepared to hear the above objections if your patch adds some crack-ridden configuration option. http://pobox.com/~hp/free-software-ui.html http://pobox.com/~hp/features.html Q: Will Muffin be part of GNOME? A: It is not officially part of GNOME as of GNOME 2.27. We are hoping to have muffin officially included as of GNOME 2.28. Q: Why does Muffin remember the workspace/position of some apps but not others across logout/login? A: Muffin only stores sizes/positions for apps that are session managed. As far as I can determine, there is no way to attempt to remember workspace/position for non-session-aware apps without causing a lot of weird effects. The reason is that you don't know which non-SM-aware apps were launched by the session. When you initially log in, Metacity sees a bunch of new windows appear. But it can't distinguish between windows that were stored in your session, or windows you just launched after logging in. If Metacity tried to guess that a window was from the session, it could e.g. end up maximizing a dialog, or put a window you just launched on another desktop or in a weird place. And in fact I see a lot of bugs like this in window managers that try to handle non-session-aware apps. However, for session-aware apps, Muffin can tell that the application instance is from the session and thus restore it reliably, assuming the app properly restores the windows it had open on session save. So the correct way to fix the situation is to make apps session-aware. libSM has come with X for years, it's very standardized, it's shared by GNOME and KDE - even twm is session-aware. So anyone who won't take a patch to add SM is more archaic than twm - and you should flame them. ;-) Docs on session management: http://www.fifi.org/doc/xspecs/xsmp.txt.gz http://www.fifi.org/doc/xspecs/SMlib.txt.gz See also the ICCCM section on SM. For GNOME apps, use the GnomeClient object. For a simple example of using libSM directly, twm/session.c in the twm source code is pretty easy to understand. Q: How about adding viewports in addition to workspaces? A: I could conceivably be convinced to use viewports _instead_ of workspaces, though currently I'm not thinking that. But I don't think it makes any sense to have both; it's just confusing. They are functionally equivalent. You may think this means that you won't have certain keybindings, or something like that. This is a misconception. The only _fundamental_ difference between viewports and workspaces is that with viewports, windows can "overlap" and appear partially on one and partially on another. All other differences that traditionally exist in other window managers are accidental - the features commonly associated with viewports can be implemented for workspaces, and vice versa. So I don't want to have two kinds of workspace/desktop/viewport/whatever, but I'm willing to add features traditionally associated with either kind if those features make sense. Q: Why is the panel always on top? A: Because it's a better user interface, and until we made this not configurable a bunch of apps were not getting fixed (the app authors were just saying "put your panel on the bottom" instead of properly supporting fullscreen mode, and such). rationales.txt has the bugzilla URL for some flamefesting on this, if you want to go back and relive the glory. Read these and the bugzilla stuff before asking/commenting: http://pobox.com/~hp/free-software-ui.html http://pobox.com/~hp/features.html Q: Why is there no edge flipping? A: This one is also in rationales.txt. Because "ouija board" UI, where you just move the mouse around and the computer guesses what you mean, has a lot of issues. This includes mouse focus, shade-hover mode, edge flipping, autoraise, etc. Metacity has mouse focus and autoraise as a compromise, but these features are all confusing for many users, and cause problems with accessibility, fitt's law, and so on. Read these and the bugzilla stuff before asking/commenting: http://pobox.com/~hp/free-software-ui.html http://pobox.com/~hp/features.html Q: Why does wireframe move/resize suck? A: You can turn it on with the reduced_resources setting. But: it has low usability, and is a pain to implement, and there's no reason opaque move/resize should be a problem on any setup that can run a modern desktop worth a darn to begin with. Read these and the bugzilla stuff before asking/commenting: http://pobox.com/~hp/free-software-ui.html http://pobox.com/~hp/features.html The reason we had to add wireframe anyway was broken proprietary apps that can't handle lots of resize events. Q: Why no XYZ? A: You are probably getting the idea by now - check rationales.txt, query/search bugzilla, and read http://pobox.com/~hp/features.html and http://pobox.com/~hp/free-software-ui.html Then sit down and answer the question for yourself. Is the feature good? What's the rationale for it? Answer "why" not just "why not." Justify in terms of users as a whole, not just users like yourself. How else can you solve the same problem? etc. If that leads you to a strong opinion, then please, post the rationale for discussion to an appropriate bugzilla bug, or to usability@gnome.org. Please don't just "me too!" on bugzilla bugs, please don't think flames will get you anywhere, and please don't repeat rationale that's already been offered. Q: Your dumb web pages you made me read talk about solving problems in fundamental ways instead of adding preferences or workarounds. What are some examples where metacity has done this? A: There are quite a few, though many opportunities remain. Sometimes the real fix involves application changes. The metacity approach is that it's OK to require apps to change, though there are also plenty of workarounds in metacity for battles considered too hard to fight. Here are some examples: - fullscreen mode was introduced to allow position constraints, panel-on-top, and other such things to apply to normal windows while still allowing video players etc. to "just work" - "whether to include minimized windows in Alt+Tab" was solved by putting minimized windows at the *end* of the tab order. - Whether to pop up a feedback display during Alt+Tab was solved by having both Alt+Tab and Alt+Esc - Whether to have a "kill" feature was solved by automatically detecting and offering to kill stuck apps. Better, metacity actually does "kill -9" on the process, it doesn't just disconnect the process from the X server. You'll appreciate this if you ever did a "kill" on Netscape 4, and watched it keep eating 100% CPU even though the X server had booted it. - The workspaces vs. viewports mess was avoided by adding directional navigation and such to workspaces, see discussion earlier in this file. - Instead of configurable placement algorithms, there's just one that works fairly well most of the time. - To avoid excess CPU use during opaque move/resize, we rate limit the updates to the application window's size. - Instead of configurable "show size of window while resizing," it's only shown for windows where it matters, such as terminals. (Only use-case given for all windows is for web designers choosing their web browser size, but there are web sites and desktop backgrounds that do this for you.) - Using startup notification, applications open on the workspace where you launched them, not the active workspace when their window is opened. - and much more. Q: I think muffin sucks. A: Feel free to use any WM you like. The reason metacity follows the ICCCM and EWMH specifications is that it makes metacity a modular, interchangeable part in the desktop. libwnck-based apps such as the GNOME window list will work just fine with any EWMH-compliant WM. Q: Did you spend a lot of time on this? A: Originally the answer was no. Sadly the answer is now yes. Q: How can you claim that you are anti-crack, while still writing a window manager? A: I have no comment on that. muffin-5.2.1/.github/0000775000175000017500000000000014211404421014474 5ustar jpeisachjpeisachmuffin-5.2.1/.github/ISSUE_TEMPLATE.md0000664000175000017500000000045014211404421017200 0ustar jpeisachjpeisach ``` * muffin version (muffin --version or 'dpkg --list | grep libmuffin0' for Mint/Ubuntu) * Distribution - (Mint 17.2, Arch, Fedora 25, etc...) * Graphics hardware *and* driver used * 32 or 64 bit ``` **Issue** **Steps to reproduce** **Expected behaviour** **Other information** muffin-5.2.1/MAINTAINERS0000664000175000017500000000016014211404421014626 0ustar jpeisachjpeisachTomas Frydrych Email: tf linux intel com Userid: tomasf Owen Taylor Email: otaylor redhat com Userid: otaylor muffin-5.2.1/po/0000775000175000017500000000000014211404421013552 5ustar jpeisachjpeisachmuffin-5.2.1/po/uk.po0000664000175000017500000060035314211404421014540 0ustar jpeisachjpeisach# Copyright (C) 2001 Free Software Foundation, Inc. # Yuriy Syrota , 2001, 2002. # Maxim Dziumanenko , 2004-2008 # Korostil Daniel , 2011, 2012. msgid "" msgstr "" "Project-Id-Version: metacity\n" "Report-Msgid-Bugs-To: \n" "POT-Creation-Date: 2012-03-18 17:38+0200\n" "PO-Revision-Date: 2012-03-18 17:42+0300\n" "Last-Translator: Korostil Daniel \n" "Language-Team: translation@linux.org.ua\n" "Language: uk\n" "MIME-Version: 1.0\n" "Content-Type: text/plain; charset=UTF-8\n" "Content-Transfer-Encoding: 8bit\n" "Plural-Forms: nplurals=3; plural=(n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%" "10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);\n" "X-Generator: Virtaal 0.7.1\n" #: ../src/50-muffin-windows.xml.in.h:1 msgid "Windows" msgstr "Вікна" #: ../src/50-muffin-windows.xml.in.h:2 msgid "View split on left" msgstr "Перегляд розділити ліворуч" #: ../src/50-muffin-windows.xml.in.h:3 msgid "View split on right" msgstr "Перегляд розділити праворуч" #.
