If I wanted to add a callback to a button for when the user right-clicked, how would I go about doing that? (note: right click does not activate the button, only left click does, and therefore the normal "button callback" won't work). I figure I probably need to intercept the event before the button is able to interpret it, and if it's not a right click, then pass the event on.  So far I found: (event-dispatch-handler (lambda (x) (display "that was event: ") (display x))) But didn't see a way to get the event out of "x".
