Re: event/notification for focus?

I don't even understand why it's so difficult to be notified that the
focus has switched to another control... To me it's a pretty basic
thing that should've been included in the API as an event (onFocus) or
a notification (NSFocusChanged). :)

If anyone has a code snippet to share it would really be appreciated!
