If you really mean main window in the NSWindow sense (makeMainWindow),
then you will want to look at the windowShouldClose delegate method
(as mentioned by Jack) and observe the
NSWindowDidResignMainNotification notification for the window so you
can set it back.
More likely, though, you should be looking at NSPanel for your other
windows. If they're stealing mainWindow status, NSPanel will fix that
because it will refuse to become main. If NSPanel does not meet you
need, you can make your own subclass of NSWindow or NSPanel to get
what you're looking for.

Hi,
My app is not a document-based application. And it has a main window
and other windows.
What I want to ask you to tell me is how to remain still the main
window even if user
option-clicks the close box of one of the other windows.
I tried observing with its name nil and object nil. But I couldn't
get which notification
actually makes the windows close.
Would you tell me how to remain the main window? Of course, it must
close if user clicks
the close box of the window.
Any suggestions would be appreciated.
