What is tab component of the JTabbedPane?

Question

Working with a JTabbedPane, if you cilck the tab it receives focus onto the text within the tab. Of course the tab itself receives focus, but if you click again, focus is transfered, as I said, onto the component containg the text.
I'd like to implement an action to this component, but cannot determine how to access it. Reading this unanswered thread shows someone else having a very similar problem. It is quite old, so I'm hoping someone has found a solution.
