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
