NSWindow that is unaffected by Expose

Question

Is there any way to make a window completely unaffected by Expose, just like the Dock? Setting the level to NSDockWindowLevel doesn't help. I know about NSWindowCollectionBehaviorStationary, but I want the window not to fade when Expose is active.

If it is not possible, is there any way to "unfade" the window after Expose fades it?

Answer 1

There's no way as far as I know.

Also, there's no reliable way to know that you're in Expose mode.
