I agree - and have run into the same problems. If you hit on a
solution please let me know. I dont think tracking rectangles are the
answer. There are things you might want to track that arent
rectangular. Also there was some posts on this list recently that
having large amounts of tracking rectangles (look up "Tooltips - what a
pathetic joke..." on
http://cocoa.mamasam.com/) greatly slowed down
scrolling.
Of course you could have a repeating task for each view that gets the
current mouse location and does its own tracking. But that doesnt seem
very friendly.
The problem with using mouseMoved events in this way - is that they
fire even if the mouse movement took place outside the view. So if you
had many views - all receiving mouseMoved events - it could overwhelm
the event queue. Id like a MouseMovedInView event that only went to
the one view the mouse moved in - even if that view isnt the first
responder.
