Technical Q&A QA1355
Why aren't my tracking rects working?
Q: I'm trying to implement tracking rectangles so that I can recieve -
mouseEntered: and -mouseExited: messages and provide visual feedback
to the user. I've sent my view an -
addTrackingRect:owner:userData:assumeInside:message, but it seems to
have no effect.
A: This symptom usually results from trying to set tracking rectangles
before your view has been added to a window.
Although NSView implements the -
addTrackingRect:owner:userData:assumeInside: method, the list of
tracking rectangles is kept by the window, not the view. When your -
initWithFrame: method is executed, your view is not yet associated
with any window, so the view can't actually set any tracking rects.
A better place to send your -addTrackingRect:.. messages is in a -
viewDidMoveToWindow: or -awakefromNib method.
