Fixed bug #901 Tim Angus 2009-12-11 11:45:46 PST Disable mouse event generation when state is not SDL_APPMOUSEFOCUS If a Windows SDL application is minimised by using alt-tab, SDL_APPMOUSEFOCUS is lost as part of the minimisation. Unfortunately, the directx driver doesn't pay any attention to this state when generating mouse button events, so clicking on the Desktop can cause mouse clicks in the SDL application, while it's still minimised. The attached patch fixes this. It looks much more complicated than it actually is due to indentation; here it is ignoring whitespace: tma@abraxas:~/sources/SDL-1.2-svn$ svn diff -x -b Index: src/video/windx5/SDL_dx5events.c =================================================================== --- src/video/windx5/SDL_dx5events.c (revision 5376) +++ src/video/windx5/SDL_dx5events.c (working copy) @@ -374,10 +374,9 @@ if ( !(SDL_GetAppState() & SDL_APPMOUSEFOCUS) ) { mouse_lost = 1; ClipCursor(NULL); - } - + } else { /* If the mouse was lost, regain some sense of mouse state */ - if ( mouse_lost && (SDL_GetAppState() & SDL_APPMOUSEFOCUS) ) { + if ( mouse_lost ) { POINT mouse_pos; Uint8 old_state; Uint8 new_state; @@ -548,6 +547,7 @@ if ( xrel || yrel ) { post_mouse_motion(1, xrel, yrel); } + } } /* The main Win32 event handler */

SDL_CreateYUVOverlay \- Create a YUV video overlay

\fBSDL_Overlay *\fBSDL_CreateYUVOverlay\fP\fR(\fBint width, int height, Uint32 format, SDL_Surface *display\fR);
.SH "DESCRIPTION"
.PP
\fBSDL_CreateYUVOverlay\fP creates a YUV overlay of the specified \fBwidth\fR, \fBheight\fR and \fBformat\fR (see \fI\fBSDL_Overlay\fR\fR for a list of available formats), for the provided \fBdisplay\fR\&. A \fI\fBSDL_Overlay\fR\fR structure is returned\&.
.PP
The term \&'overlay\&' is a misnomer since, unless the overlay is created in hardware, the contents for the display surface underneath the area where the overlay is shown will be overwritten when the overlay is displayed\&.
