how do I determine when cursor is over a point Roi in an overlay?

I'm writing a Java plugin in which I'd like to be able to dynamically detect when the cursor is directly over an Roi label in an overlay.  I know ImageJ is already doing this behind the scenes, because if I have an image with an overlay consisting of several point Roi's, the cursor changes from a cross to a "hand" if I'm over any of the point selections (indicating the underlying point Roi can be moved).  I can't seem to find the right EventListener to detect this kind of change.

Any hints on how to track this kind of event?

Thanks in advance,
