Question

I am trying to respond to a click within a textfield. When the click occurs, I am going to open a panel. My initial thought was to use a delegate method to respond to the click event – but I found that:

This method doesn’t work:

(void)textDidBeginEditing:(NSNotification *)aNotification 

This method does work, but only when I actually edit the text within the text field, not when I first click it. And – if I edit the text a second time, this method stops working:

(void)controlTextDidBeginEditing:(NSNotification *)aNotification 

---

I could use as much detail as possible – or a code example, ideally. I know that an nstextfield inherits from NSControl, which has a mouseDown event. Is there a similar way to respond to the event with a textfield, also?

Answer 1

Since NSTextField inherits from the NSControl class, it also inherits the -(void)mouseDown:(NSEvent*) theEvent method.
