I have a need to capture the RETURN/ENTER key in a NSTextView control. I have subclassed the NSTextView and overridden the keyDown: method.

-(void)keyDown:(NSEvent *)theEvent { // test to see if the user hit the enter key. If they do then process the text edit. if( theEvent characters] characterAtIndex:0] == 13 ) { // let the controller know about the return key was hit. [[[[NSNotificationCenter defaultCenter] postNotificationName:@”ReturnKeyHit” object:self]; } else { [super keyDown:theEvent]; } }

I am using a Notification to message back to the controller (or any other listening object). Is this correct way of handling this. I can’t figure out how to use the Target/Action pattern to do the same thing.

Any suggestions on using a custom control to message to controller object? Should I be using the delegate pattern?
