------- 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). --HG-- branch : SDL-1.2 extra : convert_revision : svn%3Ac70aab31-4412-0410-b14c-859654838e24/branches/SDL-1.2%402115 |

Simple DirectMedia Layer
(SDL)
Version 1.2
---
http://www.libsdl.org/
This is the Simple DirectMedia Layer, a general API that provides low
level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
and 2D framebuffer across multiple platforms.
The current version supports Linux, Windows, Windows CE, BeOS, MacOS,
Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX.
The code contains support for AmigaOS, Dreamcast, Atari, AIX, OSF/Tru64,
RISC OS, SymbianOS, and OS/2, but these are not officially supported.
SDL is written in C, but works with C++ natively, and has bindings to
several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
Pike, Pliant, Python, Ruby, and Smalltalk.
This library is distributed under GNU LGPL version 2, which can be
found in the file "COPYING". This license allows you to use SDL
freely in commercial programs as long as you link with the dynamic
library.
The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation is available in HTML format in "docs/index.html", and
a documentation wiki is available online at:
http://www.libsdl.org/cgi/docwiki.cgi
The test programs in the "test" subdirectory are in the public domain.
Frequently asked questions are answered online:
http://www.libsdl.org/faq.php
If you need help with the library, or just want to discuss SDL related
issues, you can join the developers mailing list:

Enjoy!
