If you want to intercept tabbed panel selection, I'd implement a custom SingleSelectionModel and assign that to the JTabbedPane object in question. Swing's philosophy is that behavior is controlled separately from the look of widgets (the MVC principle). Hence, you have model interfaces, which are separate from the UI interfaces. I've never tried overriding a JTabbedPane's model and the API docs aren't quite clear on what happens if the SingleSelectionModel refuses to respond to setSelectionIndex(int), but my gut tells me it'll work, since JTabbedPane is probably listening for the model object to fire a ChangeEvent to begin changing the tab.
