NSWindow - how to know if a window is hidden vs. minimized?

Question

A NSWindow can be hidden via orderOut: or minimized.

How can I distinguish between the two? isVisible returns 0 in both cases.

If -isMiniaturized isn't working for you, you can manually keep track of the window's miniaturization status by setting up your own status flag that you update when the window is minimized/de-minimized, using either of the following methods:

• Set up a window delegate that implements windowDidMiniaturize: & windowDidDeminiaturize:

• Set up an observer for the window notifications, NSWindowDidMiniaturizeNotification & NSWindowDidDeminiaturizeNotification.
