NSStepper and notification

Hi,

I have an NSStepper which changes the int value of an NSTextField
adjacent to it (linked them in IB).
I need to be notified when the stepper value changes or thusly when the
textfield changes.
NSStepper does not seem to generate any delegate messages, and when I
set a delegate to listen to textDidChange on the NSTextField I do not
get called (I guess this notification only happens if the user typed a
change)
So how do I determine when the stepper has been spun?

kind regards,

Graham
