Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. xball-3.1.0/Makefile.am000066400000000000000000000051441411065647700146700ustar00rootroot00000000000000## IMPORTANT - If you change this file, run the bootstrap script again SUBDIRS = desktop X11/Xaw_d man_MANS = xball.6 bin_PROGRAMS = xball xball_SOURCES = xball.c color_l.c demo.c file_sel.c sim.c \ help.c item.c items.c list.c menu.c misc.c miscx.c room.c \ table.c xball_sys.c scrollbar.c noinst_HEADERS = act_area.h color_l.h demo.h fallback.h file_sel.h \ help.h intf.h item.h items.h list.h menu.h misc.h miscx.h \ names.h patchlevel.h room.h scrollbar.h sim.h table.h \ xball_sys.h xball_LDADD = -L/usr/X11R6/lib -lXm -lXmu -lXt -lX11 RUN_DEMOS_HEADER = "d=${datarootdir}/xball" nodist_bin_SCRIPTS = run_demos run_demos: run_demos.in echo "#!/bin/sh" > run_demos echo "d=${datarootdir}/xball" >> run_demos cat ${srcdir}/run_demos.in >> run_demos chmod +x run_demos do_subst = sed -e 's,[@]xball[@],$(datarootdir)\/xball,' $< > $@ demo1.xball : demo1.xball.in $(do_subst) < $(srcdir)/demo1.xball.in > demo1.xball demo2.xball : demo2.xball.in $(do_subst) < $(srcdir)/demo2.xball.in > demo2.xball demo3.xball : demo3.xball.in $(do_subst) < $(srcdir)/demo3.xball.in > demo3.xball demo4.xball : demo4.xball.in $(do_subst) < $(srcdir)/demo4.xball.in > demo4.xball demo5.xball : demo5.xball.in $(do_subst) < $(srcdir)/demo5.xball.in > demo5.xball demo6.xball : demo6.xball.in $(do_subst) < $(srcdir)/demo6.xball.in > demo6.xball demo12.xball : demo12.xball.in $(do_subst) < $(srcdir)/demo12.xball.in > demo12.xball demo13.xball : demo13.xball.in $(do_subst) < $(srcdir)/demo13.xball.in > demo13.xball demo14.xball : demo14.xball.in $(do_subst) < $(srcdir)/demo14.xball.in > demo14.xball # example demo programs dist_DEMOSin = demo1.xball.in demo2.xball.in demo3.xball.in demo4.xball.in \ demo5.xball.in demo6.xball.in demo12.xball.in demo13.xball.in \ demo14.xball.in nodist_DEMOS = demo1.xball demo2.xball demo3.xball demo4.xball demo5.xball \ demo6.xball demo12.xball demo13.xball demo14.xball dist_DEMOS = demo7.xball demo8.xball demo9.xball demo10.xball demo11.xball IMAGES = xball-a.xbm xball-b.xbm xball-l.xbm xball.xbm xball-x.xbm \ man.xbm off.xbm on.xbm sgi.xbm demosdir = ${datarootdir}/xball demos_DATA = ${dist_DEMOS} ${nodist_DEMOS} ${IMAGES} EXTRA_DIST = run_demos.in ${dist_DEMOS} ${dist_DEMOSin} ${IMAGES} \ act_area.c bootstrap filemenu.c gen_fallback good_bitmaps \ stipple.xbm XBall.ad xball.6 ${noinst_HEADERS} MOSTLYCLEANFILES = run_demos DISTCLEANFILES = run_demos uninstall-hook: if test -d ${datarootdir}/xball; then rmdir ${datarootdir}/xball; fi clean-local: -rm -rf run_demos ${nodist_DEMOS} distclean-local: -rm *~ -rm -rf autom4te.cache -rm -rf .deps -rm -rf ${nodist_DEMOS} xball-3.1.0/NEWS000066400000000000000000000003511411065647700133260ustar00rootroot000000000000002005-02-23 I have been unable to locate the upstream author of xball and plan to take over this project.

You create the balls in a variety of ways, and can set the gravity, elasticity, whether balls collide or not, etc. Since the last version, I have added Motif support, 3-d shaded balls, and a demo running facility. Software features user-configurable menus, and a DrawingArea widget for use with other Athena widgets. XBall compiles using either Motif or Athena Widgets (See the Imakefile to select the one you want). It been compiled and run on a Sun Sparc, IBM RS6000, SGI Iris and DecStation 5000, using their standard C compiler. The Athena version works using X11R4 or X11R5. To compile, run xmkmf (and Make Makefiles if Athena widgets used). Then make. A standard Make.motif and Make.athena have been provided if you do not have xmkmf. If you have undefined symbols, such as usleep or regex, see the Imakefile for symbols to define, xmkmf, remove the *.o files, and recompile. All resources are contained within the program as fallback resources, so, it is not strictly neccessary to install the app-defaults file, except that when using Athena widgets, since the keyboard accelertors will not work if the app-defauls file is not installed. To run the included demos, type 'run_demos'. Here are the recommended values for the delay to slow down balls. This delay can be set in the Imakefile, or when run as xball -delay 1000.

This widget follows Motif's DrawingArea widget closely, except that it follows Athena's naming conventions and there is no resize policy. Also, Motif's Drawing area is a composite widget, while this one is a simple widget. This widget is NOT officially part of the Athena widget set. DESCRIPTION The DrawingArea widget is modeled after Motif's DrawingArea widget. The DrawingArea widget is an empty widget that is easily adaptable to a variety of purposes. It does no drawing and defines no behavior except for invoking callbacks. Callbacks notify the application when graphics need to be drawn (exposure events or widget resize) and when the widget receives input from the keyboard or mouse. Applications are responsible for defining appearence and behavior as needed in response to DrawingArea callbacks. Classes DrawingArea inherits behavior and resources from the Core and Simple classes. The class pointer is DrawingAreaWidgetClass. The class name is DrawingArea. New Resources Name Class RepType Default Value ---- ----- ------- ------------- exposeCallback Callback Pointer NULL inputCallback Callback Pointer NULL motionCallback Callback Pointer NULL resizeCallback Callback Pointer NULL XtNexposeCallback Specifies list of callbacks that is called when DrawingArea recieves an exposure event. The callback reason is XawCR_EXPOSE. XtNinputCallback Specifies list of callbacks that is called when DrawingArea recieves an keyboard or mouse event (key or button, up or down). The callback reason is XawCR_INPUT. XtNmotionCallback Specifies list of callbacks that is called when DrawingArea recieves a mouse motion event. The callback reason is XawCR_MOTION. XtNresizeCallback Specifies list of callbacks that is called when the DrawingArea is resized. The callback reason is XawCR_RESIZE. Inherited Resources, Changed defaults Name Class RepType Default Value ---- ----- ------- ------------- height Height Dimension 100 width Width Dimension 100 Callback Information A pointer to the following structure is returned with each callback. typedef struct { int reason; XEvent *event; Window window; } XawDrawingAreaCallbackStruct; reason: Indicates why the callback was invoked event: Points to the XEvent that triggered the callback window: Is set to the widget window Behavior ,,,: The callbacks for XtNinputCallback are called when a key or button is pressed or released. : The callbacks for XtNexposeCallbacks are called when the widget recieves an exposure event. : The callbacks for XtNresizeCallbacks are called when the widget is resized. : The callbacks for XtNmotionCallbacks are called when the widget recieves a pointer motion event.

This program simulates bouncing balls in a window. You create the balls in a variety of ways, and can set the gravity, elasticity, whether balls collide or not, etc.

Young children enjoy watching the balls bounce around the screen and are fascinated by the program. This is an ideal program for teaching rudimentary mouse skills to very young children.

To run the 14 included demo scripts, open a console terminal and type 'run_demos' to see each demo one after the next.

Software features user-configurable menus, and a DrawingArea widget for use with other Athena widgets.

All resources are contained within the program as fallback resources, so, it is not strictly neccessary to install the app-defaults file, except that when using Athena widgets, since the keyboard accelertors will not work if the app-defauls file is not installed.

To run the included demos, open a console terminal and type 'run_demos'.

Documentation is included on-line via the Help menu and is not reproduced here. .SH OPTIONS Run xball \-help for a description of the command line options .SH DEMOS Several demo files are included with the distribution. To run all the demos, run 'run_demos'. .SH RESOURCES Most resources are available for user modification. See the XBall app-defaults file for a complete listing of widgets, .sp Following is a list of the most useful resources: .RS .TP 3 \fBXBall*canvas.width, height\fR The default width and height of the window in which balls bounce in. .TP 3 \fBXBall.delay\fR The amount to slow the simulation, in case the computer is too fast. A reasonable range is 0 to 200. .TP 3 \fBXBall.itemWidth, itemHeight\fR The default width and height of the balls. .TP 3 \fBXBall.collide\fR If true, balls are colliding on startup. .TP 3 \fBXBall.perpetual\fR If true, balls are perpetual on startup. .TP 3 \fBXBall.haltSim\fR If true, simulation is halted on startup. .TP 3 \fBXBall.demoFile\fR Specified the file to run as a demo on startup. .TP 3 \fBXBall.rgbTxt\fR Specified the file to load for the colors. The default file is /usr/share/X11/rgb.txt .SH FILES .TP /usr/share/X11/rgb.txt X11 color names and values. .sp .SH AUTHOR .PP David Nedde (daven@ivy.wpi.edu). .br Packaged for the Debian project by Stephen Birch . .sp .SH COPYRIGHT Copyright 1991, 1993 David Nedde. .br Permission to use, copy, modify, and distribute this software and its documentation for any purpose and without fee provided that the above copyright notice appears in all copies.
