You must mean textShouldBeginEditing, right?

I checked the documentation for NSTextField and there is a delegate
message:
- (BOOL)shouldBeginTextEditing:(NSText *)textObject
I set up a simple XCode project with an NSTextField in a window, and set
it's delegate to my custom Controller object. In my Controller object, I
implemented the shouldBeginTextEditing method, but it was never called (I
had an NSLog in there). Am I missing the point of this message? (according
to the docs: "If it is editable and its delegate responds to
control:textShouldBeginEditing:, invokes that method and returns the
result.") and the docs of NSControl's control:textShouldBeginEditing:
delegate message says:
"Sent directly by control to the delegate when the user tries to enter a
character in a cell of a control that allows editing of text (such as a
text field or form field). Return YES if the NSControl?s fieldEditor should
be allowed to start editing the text, NO otherwise."
My 2 cents, with a sample that doesn't work...
