Hi Amin,
Unless I am misunderstanding, this would tell me if it was onscreen,
but not if the window was exposed (not hidden by other windows).

Hey folks,
I'd like to fade my window out if any portion of it is visible to the
user, otherwise I simply want to close it for speed. Is there an easy
way to determine if some portion of the window is visible?
I do not know, whether this is a "dirty" hack (are there clean
hacks?), but you can read the frames of the screens
http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSScreen_Class/Reference/Reference.html#/
/apple_ref/occ/clm/NSScreen/screens
http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSScreen_Class/Reference/Reference.html#/
/apple_ref/occ/instm/NSScreen/frame
and clip it with you window frame.
http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSWindow_Class/Reference/Reference.html#/
/apple_ref/occ/instm/NSWindow/frame
That probably works.
Cheers,
Amin
Thanks!
Jason
