Date: Sun, 3 Aug 2003 22:07:57 +0200 From: Max Horn Subject: SDL OSX fullscreen FIX the attached patch fixes the fullscreen problems on SDL/OSX. The cause was that click events are bounded by winRect. Now, winRect is set to the size of the video surface. But if you e.g. request a 640x420 surface, you might get a 640x480 "real" surface. Still, SDL_VideoSurface->h will be set to 420! Thus, the upper 60 pixels in my example received no mouse down events. My fix simply disables this clipping when in full screen mode - after all, all clicks then should be inside the screen surface. Higher SDL functions ensure that the coordinates then are clipped to 640x420. It works fine in all my tests here. I don't know if it's the right thing to do in multi screen scenarios, though.
