view TODO @ 4168:69bcba65c388 SDL-1.2

Fixed bug #526 Comment #1 From Simon Howard 2009-03-20 16:50:56 Hi, I'm the author of Chocolate Doom, one of the other source ports that James mentioned. This is a patch against the current SVN version of SDL 1.2 that fixes the bug. It has been tested and hopefully should be obviously correct from examining the changes. I'll give a brief explanation. When the palette is set with SDL_SetPalette, the IDirectDrawPalette_SetEntries DirectX function is invoked. However, when this happens, a WM_PALETTECHANGED message is sent to the window. A WM_PALETTECHANGED message can also be received if the palette is changed for some other reason, like if the system palette is changed. Therefore, the palette change handler (DX5_PaletteChanged) has code to deal with this case. It distinguishes "expected" palette changes (set with SDL_SetPalette) from "unexpected" palette changes using the colorchange_expected variable, which is set before calling IDirectDrawPalette_SetEntries. However, the code to set this variable is missing in the fullscreen code path. By setting this variable, the palette change is handled properly and the freezes go away.

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)
