问题
how can I take notice when an NSWindow should or will get closed? I'd like to have something like the windowWillClose. Unfortunately NSWindowController does not have as much convenient methods as UIViewController has, for example. So what's the best practice to do that?
Thanks

According to the NSWindow docs, a window will post a NSWindowWillCloseNotification notification when it is about to close. Your controller can observe this notification.
