Louis,
Thanks for the response. The first thing I tried was the delegate
method '- textShouldBeginEditing:', but that only gets called if you
actually attempt to make a change. What I want is to do something
when the text field becomes the first responder, which is why I
subclassed to override becomeFirstResponder.
I wonder if the text field upon becoming first responder immediately
resigns in favor of the field editor. This would give the behavior I
have observed (resignFirstResponder being called immediately, not
when the text field loses focus).
'- textShouldEndEditing:' looks to be triggered when the insertion
point leaves the text field, so I think I can use this to do what I
want and not worry about resignFirstResponder.
Regards,
Don
Hello....
When a text field is being edited, the shared "field editor" object
is used as the first responder, not the text field. Check out the
documentation for the NSWindow method fieldEditor:forObject: for
more information on this.
Depending on what you are trying to do, you also might want to look
at using the delegate methods provided by NSTextField (or the
equivalent NSControl delegate methods) instead:
- textShouldBeginEditing:
- textDidBeginEditing:
- textDidChange:
- textShouldEndEditing:
- textDidEndEditing:
Hope that helps,
Louis

When I tab into one of these text fields I get both messages:
2004-04-07 00:02:22.712 MyApp[8922] becomeFirstResponder
2004-04-07 00:02:22.740 MyApp[8922] resignFirstResponder
When I tab out, I get no messages.
The panel containing the text field remains key (frontmost).
Can anyone explain this? It looks like I am doing the same thing as
in Anguish et al page 586.
Thanks,
Don
