Date: Tue, 21 Aug 2001 03:50:01 +0200 From: Max Horn <max@quendi.de> Subject: New patch for OS X Attached a .patch file for SDL/OSX with some nice bug fixes / enhancments. * fixes the activation issues, which also caused the window to be always drawn like an inactive. The close/minimize widgets now are animated properly, too. * the menu items are automatically adjusted to use the app name instead of just "SDL App". I did this so that we really can use one central SDLMain.nib file, w/o requiring developers to make a copy of it and adjust it. * libSDLMain now contains the proper cocoa code, not as before the carbon code. This means apps no longer have to carry a copy of SDLMain.m/SDLMain.h * revamped configure.in to properly build a Cocoa/Quartz SDL lib, not a Carbon based SDL lib
