Date: Tue, 5 Oct 2004 11:04:02 -0400 From: Bob Ippolito Subject: [SDL] PATCH: Fix for release count bug in SDL_QuartzWM SDL_QuartzWM incorrectly does [window close]; [window release]; The semantics for -[NSWindow close] are as follows: Removes the receiver from the screen. If the receiver is set to be released when closed, a release message is sent to the object after the current event is completed. For an NSWindow object, the default is to be released on closing, while for an NSPanel object, the default is not to be released. You can use the setReleasedWhenClosed: method to change the default behavior. This patch simply removes the incorrect release.
