Date: Thu, 2 Sep 2004 19:35:51 +0200 From: Max Horn Subject: [Patch]: Improved menu code for SDLMain.m the attached patch improves the menu setup for SDL apps built without a .nib file. On 10.3, the application menus are empty with the current SDL CVS version; after this patch, a proper app & window menu, with "About", "Hide", "Quit", "Minimize" etc. entries are visible, just like with the .nib enabled applications. This *should* work on 10.2 and even 10.1, but I can't guarantee it, so somebody should test there, ideally. I also changed the way setupWorkingDirectory works by making use of the Bundle APIs, that results in (IMO) less hackish code. Finally, I added some "static" keywords to ensure that certain local functions are not exported (that's just a paranoia change, I guess: never pollute linker namespaces if you can avoid it).

>SDL provides several cross-platform functions for dealing with time.
It provides a way to get the current time, a way to wait a little while,
and a simple timer mechanism.  These functions give you two ways of moving an
object every x milliseconds:

>Use a timer callback function.  This may have the bad effect that it runs in a seperate thread or uses alarm signals, but it's easier to implement.</P

>Or you can get the number of milliseconds passed, and move the object if, for example, 30 ms passed.</P
