NSDatePicker - getting the value when it is changed

Question

How would I get notified of a value of a NSDatePicker, when it's changed?

Answer 1

I've only done it on the iPhone with UIDatePicker but it is similar on the Mac, you register as a delegate and receive messages. See Apple's Docs here.

I should clarify, this tells you when it changed, you still need to call -dateValue to get the date.
