Discussion
This method is part of the window restoration system and is called at launch time to restore the visual state of your responder object. The default implementation does nothing but specific subclasses (such as NSView
and NSWindow
) override it and save important state information. Therefore, if you override this method, you should always call super
at some point in your implementation.
Subclasses can override this method and use it to restore any information that was saved in the encode
method. You can also use this method to reconfigure the responder to its previous appearance.
