ShowWindow/HideWindow in Cocoa

In Carbon you could change a window's visibility with HideWindow(WindowRef) and ShowWindow(WindowRef).

In Cocoa I know you can call NSWindow's orderOut: to hide and orderFront:, orderBack: or orderWindow:relativeTo: to put it back on screen, but none of those respect the ordering of the window relative to other windows when it was last visible.

For example, if I have two windows, one above the other, and then call orderOut: on the back window, how do I show the window again such that it is still behind the front window without calling orderWindow:relativeTo:.

The only thing I can think of right now is to remember the window ID of the window immediately above it and then use orderWindow:relativeTo: when showing it again, but I haven't thought through what happens if the window above is closed before the rear window is made visible again.

I don't think there's any method available in Cocoa. I guess you need to mimic that using your idea.

By the way, what was the Carbon behavior if you start from four windows ordered as

 A B X C D E

Then hide X

 A B C D E

Now the user reorders them, and removes some:

 E A C

and then show X again. Where did X go in Carbon in this case?
