11 * And remember: X Windows is to graphics hacking as roman numerals are to
12 * the square root of pi.
15 /* This file contains simple code to open a window or draw on the root.
16 The idea being that, when writing a graphics hack, you can just link
17 with this .o to get all of the uninteresting junk out of the way.
19 Create a few static global procedures and variables:
21 static void *YOURNAME_init (Display *, Window);
23 Return an opaque structure representing your drawing state.
25 static unsigned long YOURNAME_draw (Display *, Window, void *closure);
28 The `closure' arg is your drawing state, that you created in `init'.
29 Return the number of microseconds to wait until the next frame.
31 This should return in some small fraction of a second.
32 Do not call `usleep' or loop excessively. For long loops, use a
35 static void YOURNAME_reshape (Display *, Window, void *closure,
36 unsigned int width, unsigned int height);
38 Called when the size of the window changes with the new size.
40 static Bool YOURNAME_event (Display *, Window, void *closure,
43 Called when a keyboard or mouse event arrives.
44 Return True if you handle it in some way, False otherwise.
46 static void YOURNAME_free (Display *, Window, void *closure);
48 Called when you are done: free everything you've allocated,
49 including your private `state' structure.
51 NOTE: this is called in windowed-mode when the user typed
52 'q' or clicks on the window's close box; but when
53 xscreensaver terminates this screenhack, it does so by
54 killing the process with SIGSTOP. So this callback is
57 static char YOURNAME_defaults [] = { "...", "...", ... , 0 };
59 This variable is an array of strings, your default resources.
60 Null-terminate the list.
62 static XrmOptionDescRec YOURNAME_options[] = { { ... }, ... { 0,0,0,0 } }
64 This variable describes your command-line options.
65 Null-terminate the list.
67 Finally , invoke the XSCREENSAVER_MODULE() macro to tie it all together.
71 - Make sure that all functions in your module are static (check this
72 by running "nm -g" on the .o file).
74 - Do not use global variables: all such info must be stored in the
75 private `state' structure.
77 - Do not use static function-local variables, either. Put it in `state'.
79 Assume that there are N independent runs of this code going in the
80 same address space at the same time: they must not affect each other.
82 - Don't forget to write an XML file to describe the user interface
83 of your screen saver module. See .../hacks/config/README for details.
