Subject: [SDL] ALT-F4 using DirectX
My game isn't getting SDL_QUIT when I press ALT-F4 using the DirectX
driver; it does get SDL_QUIT when I press the red X in the window.
I tracked this down to DX5_HandleMessage() in SDL_dx5events.c;
WM_SYSKEYDOWN is being trapped and ignored which causes Windows not to post
a WM_CLOSE, hence no SDL_QUIT is being generated.
The relevant code is this :
/* The keyboard is handled via DirectInput */
case WM_SYSKEYUP:
case WM_SYSKEYDOWN:
case WM_KEYUP:
case WM_KEYDOWN: {
/* Ignore windows keyboard messages */;
}
return(0);
If I comment the WM_SYSKEYDOWN case, it falls through DefWindowProc() and
ALT-F4 starts working again.
I'm not sure about the best way to fix this. One option is handling ALT-F4
as a particular case somehow, but doesn't sound good. Another option would
be to handle WM_SYSKEYDOWN separately and breaking instead of returning 0,
so processing falls through and goes to DefWindowProc which does The Right
Thing (TM). This seems to be the minimal change that makes ALT-F4 work and
normal keyboard input continues to work.
Does this sound reasonable? Am I overlooking anything? Do I submit a patch?

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. SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, C#, Eiffel, Java, Lua, ML, Objective C, Perl, PHP, Pike, Python, and Ruby. The current version supports Linux, Windows, BeOS, MacOS, MacOS X, FreeBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. The code contains support for Windows CE, AmigaOS, Dreamcast, Atari, NetBSD, AIX, OSF/Tru64, RISC OS, SymbianOS, and OS/2, but these are not officially supported. 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" 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: http://www.libsdl.org/mailing-list.php Enjoy!
