Figured it out. I just need to use
addTrackingRect:owner:userData:assumeInside

I just realized that NSTrackingArea is 10.5 and up. I need to
support 10.4. mouseEntered and mouseExited have been part of
NSResponder from 10.0. To receive these events in 10.4 what should I
do?
thanks

I'm a little confused on the mouse tracking. I have a view and I
want to track when the mouse enters and exits it. If I set
setAcceptsMouseMovedEvents to true for my window, (void)mouseMoved:
(NSEvent *)theEvent will get called. But, - (void)mouseEntered:
(NSEvent *)theEvent and - (void)mouseExited:(NSEvent *)theEvent
will not. Am I correct in my understanding that I need to create a
NSTrackingArea for these events to get called?
Yes, create a tracking area, but *don't*
setAcceptsMouseMovedEvents:YES.
Both mechanisms result in mouseMoved events, but you only want the
events produced by the tracking area. (Well, you may not want
mouseMoved events at all, just mouseEntered and mouseExited, but
you tell the tracking area which of its possible events you want.)
