Fixed bug #281 ------- Comment #2 From Christian Walther 2006-07-23 07:37 [reply] ------- Wow, that was an interesting bug to chase. It was a timing issue: it seems that for some reason, a certain time must pass between ShowMenuBar() being called in QZ_UnsetVideoMode() and the application quitting. Before rev. 1885, this delay was provided by the slow hand-coded fade. With the asynchronous Core Graphics fading introduced in rev. 1885, that delay was no longer present (most of the time) and the bug became apparent. Adding an SDL_Delay(100) somewhere between ShowMenuBar() and the end of QZ_VideoQuit() lowered the frequency of the bug appearing from "almost every time" to "very rarely" here. However, there is another solution: doing the ShowMenuBar() before releasing the captured display instead of afterwards. Apparently, no delay is necessary in that case, and it looks nicer to me anyway because it is the reverse order of the way things are set up in the beginning: capture display - set video mode - hide menu bar - ... - show menu bar - reset video mode - release captured display. So, this is what the attached patch does. In addition, I've taken the liberty of - removing some unused code that I forgot to remove in rev. 1885, - fixing two warnings about undeclared functions in SDL_QuartzVideo.m by including OpenGL.h (whose name is a bit misleading - it only declares CGL stuff, so there's no interference with SDL_opengl.h).

Wish list for the 1.3 development branch:
http://bugzilla.libsdl.org/

 * Add mousewheel events (new unified event architecture?)
 * DirectInput joystick support needs to be implemented
 * Be able to enumerate and select available audio and video drivers
 * Fullscreen video mode support for Mac OS X
 * Explicit vertical retrace wait (maybe separate from SDL_Flip?)
 * Shaped windows, windows without borders
 * Multiple windows, multiple display support
 * SDL_INIT_EVENTTHREAD on Windows and MacOS?
 * Add a timestamp to events
 * Add audio input API
 * Add hardware accelerated scaled blit
 * Add hardware accelerated alpha blits
 * Redesign blitting architecture to allow blit plugins

In the jump from 1.2 to 1.3, we should change the SDL_Rect members to
int and evaluate all the rest of the datatypes.  This is the only place
we should do it though, since the 1.2 series should not break binary
compatibility in this way.

Requests:
 * PCM and CDROM volume control (deprecated, but possible)
