I don't believe there are any notifications.  However, you shouldn't
have to do anything if using standard Cocoa widgets; it will just work.

If doing custom widgets, you will want to listen for notifications such
as when your windows become key.  You also typically override
becomeFirstResponder and resignFirstResponder.  From all such methods
you will send the setKeyboardFocusRingNeedsDisplayInRect: message as
needed.

See /Examples/AppKit/ClockControl for what to do.  Note that if you
switch out of the app to System Preferences, change the full keyboard
access setting, and return to the app, the correct thing happens.
