Hi,

I am a little confused by your question: from any spot in the view hierarchy, what other view would you be looking for? How would you know if you had found it? E.g., if you would be looking for a view via a "unique ID", how would your original view get the id in the first place, and if it got the id at some point in a program, couldn't it just as easily have gotten a reference to the view?

Maybe these methods are of use?

NSView:

- ancestorSharedWithView:
- isDescendantOf:

NSWindow:

- windowNumber

Also check the function NSWindowList at:

http://developer.apple.com/documentation/Cocoa/Reference/ ApplicationKit/ObjC_classic/Functions/AppKitFunctions.html

This mentions NSConvertWindowNumberToGlobal:

Lastly some window server/NSApp reference:

Does Cocoa allow finding an NSView? From what I can tell, there isn't any unique ID for a view, so from any spot in a view hierarchy, it doesn't seem programatically possible to find a view that's either a sibling, super, or sub view from any particular view. Is that correct? So, if you want to use any particular view, you need to set it up as an outlet, correct?
Thanks,
Mark
