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 */

.SH "NAME"
SDL_EventState \- This function allows you to set the state of processing certain events\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBUint8 \fBSDL_EventState\fP\fR(\fBUint8 type, int state\fR);
.SH "DESCRIPTION"
.PP
This function allows you to set the state of processing certain event \fBtype\fR\&'s\&.
.PP
If \fBstate\fR is set to \fBSDL_IGNORE\fP, that event \fBtype\fR will be automatically dropped from the event queue and will not be filtered\&.
.PP
If \fBstate\fR is set to \fBSDL_ENABLE\fP, that event \fBtype\fR will be processed normally\&.
.PP
If \fBstate\fR is set to \fBSDL_QUERY\fP, \fBSDL_EventState\fP will return the current processing state of the specified event \fBtype\fR\&.
.PP
A list of event \fBtype\fR\&'s can be found in the \fI\fBSDL_Event\fR\fR section\&.
