What you are looking for vis a vis a subfocus change event does not exist 
in Swing.  It really should.  

Note that subfocus change is *not* the same thing as a selection change.  
I would also argue that installing your own selection model just to get 
selection events isn't really what most people should have to do/want to 
do, but that is a different story.

When I brought this up at JavaOne to the Swing team (in the guise of 
subfocus change events for *all* components where it logically, including 
JTabbedPane, they seemed to think it was a good idea, but I wouldn't look 
for it any time soon, unfortunately.
