How to find the position of an NSCell?

Subject: How to find the position of an NSCell?

I am constructing a hierarchical tool palette and thought the best way to do this would be through using a (subclass of) NSPanel containing an NSMatrix with NSButtonCell objects.

Now, when the user presses one of the NSButtonCells I want to open a new NSPanel with the sub-choices for that button right below the pressed button but I believe that in order to position the NSPanel I will have to know the position of the button and I can't figure out any better method for finding that position than letting the button have a back reference to its containing view and its position in that view and then ask the view for the screen coordinates when needed.

Or, is there a more direct method?
