A have a Window (actually a Panel, but that's irrelevant). I have a delegate
for the Window. I connected the delegate in the Interface Builder. Now, my
problem:
When the delegate receives a message (like a call to windowDidBecomeKey), is
there a way to directly determine which Window the message is in reference to
without using an outlet in the delegate's class?
It seems like there should be an easy way to do this, but I can't seem to find
it.

My best advice is not to write code such that the question comes up at all, but if you must--read the descriptions of keyWindow (Application) and isKeyWindow (Window) and see if those tell you what you want to know. -=EPS=-

Usually, a message that your delegate receives will include a "sender" argument. This is true for the windowDidBecomeKey: delegate method. The "sender" refers to the Window object that something has happened to, so for instance, when your delegate gets a windowDidBecomeKey: message, the sender refers to the Window which just became the key window. Hope this helps. Eric Ly
