Get the gadget at a point on the screen? (Mac)

I think someone had some code to retrieve the gadget at a given point onscreen. Where is it?

The basic UI component in Cocoa is called an NSView, if you are not familiar with Apple documentation you should probably start here:

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSView_Class/Reference/NSView.html

The hitTest method is possibly of use, having a look at MaxGUI the gadget under a mousemove event if sensitive should already be possibly being reported.

I'm attempting to use the [NSView convertPoint:frame.origin toView:nil] method, but it does not act as I would expect.

Seb helped with the coordinate transformation. I'll ask him if he wants to make that code public. Now just have to get the hittest working...
