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.

SDL_JoystickEventState \- Enable/disable joystick event polling
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_JoystickEventState\fP\fR(\fBint state\fR);
.SH "DESCRIPTION"
.PP
This function is used to enable or disable joystick event processing\&. With joystick event processing disabled you will have to update joystick states with \fI\fBSDL_JoystickUpdate\fP\fR and read the joystick information manually\&. \fBstate\fR is either \fBSDL_QUERY\fP, \fBSDL_ENABLE\fP or \fBSDL_IGNORE\fP\&.

\fBNote:

Joystick event handling is prefered

.SH "RETURN VALUE"
.PP
If \fBstate\fR is \fBSDL_QUERY\fP then the current state is returned, otherwise the new processing \fBstate\fR is returned\&.
