hi,
suppose you have a JComboBox with the popup visible, the list exposed.
I want to, during a keyPressed event, be able to determine if the mouse is
hovering over (and, therefore, highlighting) one of the items in my JComboBox
list. If so, I want to get the index for that item.
Probably not as easy as it sounds, right? Any ideas?
thanks!

No, its not. While it would be nice to be able to just register a MouseListener with the JComboBox or something, it won't work correctly. What's more, you don't have access to the popup menu unless you start making assumptions about the L&F implementation. Many people have run into this (or related) problem. See here: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4144505
My solution: implement my own JComboBox. This effectively breaks the multiple L&F support. There are probably other solutions out there.
