Date: Mon, 6 Feb 2006 11:41:04 -0500 From: "mystml@adinet.com.uy" 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? --Gabriel

This is the porting of 1.2.0 version of SDL (the latest stable one)
to AmigaOS/68k.

All the bugs known of the past version have been corrected. And I've
added all the new SDL features.

This version of SDL needs Cybergraphx V3 (r69+) or CyberGraphX V4
and AHI v3+. Probably it works also with P96 or CGXAga, but it's 
untested.

This version is available as linked library for SAS/C and GCC, only 68k this 
time, a powerup (ppcemu compatible) and a morphos version will be ready quite 
soon (i hope).

Implemented:

- 8/16/24/32bit video modes, both fullscreen and windowed.
- Hardware surfaces.
- CGX blitting acceleration.
- CGX colorkey blitting acceleration.
- AHI audio (8/16 bit, with any audio format), always uses unit 0 for now.
- Thread support (maybe not 100% compatible with other implementations)
- Semaphores 
- Window resizing and backdrop windows (NEW)
- Joystick/Joypad support.

To do:

- CDRom audio playing support
- OpenGL (A guy was working on it but I've lost his tracks :( )

The SAS/C library is distributed with debug info attached, to strip debug info 
simply add STRIPDEBUG argument to the linker.

NOTE: SDL includes debug output using kprintf, to disable it add to your 
project a function like this:

void kprintf(char *a,...)
{
}

Otherwise you can redirect the debug to a console window with sushi, sashimi or
similar tools (the default output is the internal serial port).
