Date: Tue, 05 Feb 2008 01:41:08 -0500 From: Mike Miscevic Subject: SDL and capslock/numlock Find attached a patch against SDL-1.2.13 for check of SDL_NO_LOCK_KEYS environment variable. This differs slightly from other patches I've seen in that it has 3 modes: Disable CAPS-LOCK and NUM-LOCK supression of down+up key events, suitable for games where the player needs these keys to do more than just toggle. A value of 1 will effect both CAPS-LOCK and NUM-LOCK. A value of 2 will effect only CAPS-LOCK. A value of 3 will effect only NUM-LOCK. All other values have no effect. This works for me and has been tested on: - Fedora 8 64-bit - SRCRPM SDL-1.2.13-1.fc8.src.rpm - Emeny Territory Quake Wars (ETQW), native 32-bit commercial game --Mike Miscevic
