you either need to subclass or add a category to NSTextField which has a

-(BOOL) isEmpty

method.

You then need to set 'isEmpty' whenever the status of the textfield changes.

You then create an NSObjectController to control the textfield object.

You can then bind your button's 'enabled' binding to the textfield's 'isEmpty' property via the controller.

I have a button. In the same window, I have a text field. I want the button's 'enabled' state to track the whether the text field is non-empty (you can only click the button if the text field has something in it).
