Date: Sat, 8 Sep 2001 04:42:23 +0200 From: Max Horn <max@quendi.de> Subject: SDL/OSX: Joystick; Better key handling I just finished implementing improved keyhandling for OS X (in fact the code should be easily ported to the "normal" MacOS part of SDL, I just had no chance yet). Works like this: First init the mapping table statically like before. Them, it queries the OS for the "official" key table, then iterates over all 127 scancode and gets the associates ascii code. It ignores everythng below 32 (has to, as it would lead to many problems if we did not... e.g. both ESC and NUM LOCk produce an ascii code 27 on my keyboard), and all stuff above 127 is mapped to SDLK_WORLD_* simply in the order it is encountered. In addition, caps lock is now working, too. The code work flawless for me, but since I only have one keyboard, I may have not encountered some serious problem... but I am pretty confident that it is better than the old code in most cases. The joystick driver works fine for me, too. I think it can be added to CVS already. It would simply be helpful if more people would test it. Hm, I wonder if Maelstrom or GLTron has Joystick support? That would be a wonderful test application :) I also took the liberty of modifying some text files like BUGS, README.CVS, README.MacOSX (which now contains the OS X docs I long promised)
