How to keep a border even after right-clicking

Question

I have a JButton around which I would like:
1) a raised border to appear when hovering over the button,
2) a lowered border to appear when left-clicking on the button,
3) no border to appear when releasing or exiting the button, and
4) a raised border to appear when right-clicking on the button and bringing up a popup menu.
I created a MouseListener to achieve effects 1) through 3) above, but I'm having trouble achieving effect 4).
It appears that showing a popup menu causes my MouseListener's mouseExited() method to be fired. This method, though, is currently only responsible for achieving effect 3).
Is there a way to make my mouseExited() method smart enough to implement effect 4) instead of 3) if it realizes it has been invoked as a result of a popup menu display? In other words, is there a way to make a border appear around my button even when the user has opened up a popup menu for that button?
I tried interrogating the value of MouseEvent.isPopupTrigger(), but that always appears to return false in mouseExited() [ it only ever returns true for me in mouseReleased() ].
Any suggestions would be greatly appreciated.
Thanks,
Mike

Answer 1

Jay,
Thanks for your reply. Attached is my updated code that includes the popup listening logic. This logic seems to work, except for the following issues:
1) The button becomes temporarily depressed when right-clicking on it (just as you stated).
2) If I right click on a Button A to display its popup menu and then move my mouse over to another Button B, Button B becomes raised even though Button A's popup menu hasn't been dealt with yet.
Regarding issue 1) above, could I test for whether mouse BUTTON_1 or BUTTON_2 was pressed to determine whether the mouse should be depressed, or would this make my logic platform-dependent?
Regarding issue 2) above, is there a way to block other buttons from appearing raised while a popup menu still appears in support of another button? Or is there just a problem in my implementation of the popup (i.e. it doesn't expire)?
Thanks,
Mike
