I'm trying to find some way to add MouseListeners to tabs on a JTabbedPane. I can easily add them, of course, to the components denoted by the tabs, but I need them listening for MouseEvents on the actual buttons that switch tabs themselves.

So far, the only method I can think of is adding the listener to the whole JTabbedPane. If the event isn't within the currently focused component, then it must be in one of the tabs, so I compare the tooltip for that point against the tooltip of the current tab, but this won't work properly if more than one tab has the same tooltip. Anyone have any better ideas?
