Hello everyone,
I'm implementing a subclass of NSTextField and I need to intercept a
delegate message in the class before it is sent to the delegate. Is
this
possible, and if so, how?
See the docs for the methods -textDidBeginEditing:, -textDidChange:,
etc. in NSTextField. I'd suggest overriding whichever of those
corresponds to the delegate method(s) you care about. This way you
can intercept not only messages to the delegate but the corresponding
notifications. For example, the NSTextField might not have a delegate
but there might be some object out there listening for notifications.
