How can I get the on-screen location of a button in a toolbar? That is getting the rectangle frame of an NSToolbarItem? The [NSToolbarItem view] method seems to always return nil whenever the toolbar item is only a simple action button and thus I couldn't use the normal NSView methods to pinpoint the toolbar button's on-screen position.

Background

I'm trying to use Matt Gemmell's MAAttachedWindow component to point to a specific toolbar button. The component requires an NSPoint object to "point" the user to a location on the screen.

Thanks in advance.
