What kind of stuff? The window still exists when you get the windowWillClose notification, so you can safely call into it or your views.

If you're talking about interacting with the user (like confirming the close), you should implement the -windowShouldClose: delegate method. This gets called earlier, before the -close call, and by returning NO from it you can prevent the close entirely.
