I use the textShouldEndNotification and test to see if the content is
empty, if it is then i replace with my hint text, if it is not then i
leave it alone since it contains user data. When the item become first
responder, it the contained text is the hint string then i set the
content to the empty string.

I'm trying to duplicate Apple's search field UI, where a piece of
grayed-out text indicates what will be searched as long as the field
is empty and doesn't have key focus.
I've subclassed NSTextField, and I can (apparently reliably) find out
when the user begins editing by overriding -becomeFirstResponder.
Unfortunately, I don't get a corresponding -resignFirstResponder when
the user stops editing the field. I can trap -textShouldEndEditing:,
and that works most of the time, but when the user clicks in the empty
text field and then clicks away again, I don't get any notification.
How can I reliably detect when my text field has gained and lost key
focus?
Thanks,
Keith
