I had a situation similar to this with a Sheet I wanted to pop up
after the window opened. I ended up using a Timer that checked for
window visibility before acting. I would re-launch the timer until
the window was visible, then launch my sheet.
Andreas, I'm curious about your suggestion of
[NSApp performSelector:@selector(open) withObject:drawer afterDelay:0.0]
Is there anything that is substantially different from using timers?
The problem I ran into was that since I wanted the delay to be a
short as possible, I ran the risk of firing before the system was
ready. I handled this by re-launching the timer on a 0.1 second
interval until my window was visible ([myWindow isVisible]).
The need for polling like this makes me think there must be (or
should be) a better way to do this. I would prefer that the system
notify me when I can take these sorts of actions rather than having
to poll. But of course I wan't able to find anything suitable. I
suspect that some AppKit guru on this list might be able to suggest a
better way.

Well, yes. Actually, what I mean was, as a beginner, I tried Andy's
suggestion verbatim:
[NSApp performSelector:@selector(open) withObject:MyDrawer afterDelay:1.0];
and I got "NSApp does not respond to perforSelector:". Only when I
looked up performSelector: I realized it's an NSObject method so I
could do something like this.
[self performSelector:@selector(open) withObject:MyDrawer afterDelay:1.0];

Thanks Andy. It works except
performSelector:withObject:afterDelay belongs to NSObject.
NSApp is an NSObject...
