Date: Mon, 5 May 2003 00:08:51 -0400 From: Darrell Walisser Subject: SDL Active Events Patch Hi Guys, I was reading sdl-devel the other day and remembered we don't handle SDL_APPACTIVE and SDL_APPMOUSEFOCUS. I hacked together a quick patch to do just this. One thing to note - there are actually two ways to "iconify" the SDL window (which sets SDL_APPACTIVE): hiding the entire application (for example, option-click on some other window) and minimizing the window to the dock. I treat both as SDL_APPACTIVE, since the window is no longer visible. Cheers, Darrell

11 Gets a snapshot of the current keyboard state\&. The current state is return as a pointer to an array, the size of this array is stored in \fBnumkeys\fR\&. The array is indexed by the \fI\fBSDLK_*\fP\fR symbols\&. A value of 1 means the key is pressed and a value of 0 means its not\&. The pointer returned is a pointer to an internal SDL array and should not be freed by the caller\&.
