Listening to JPopupMenu invocation
How can one listen to JPopupMenu invocation? I need to disable a JPopupmenu's JButton WHEN the JPopupMenu is invoked.
Please note that I do not need to listen to a JPopupMenu's menu items, but to the popupmenu's invocation i.e. I need to execute some code WHEN the jpopupmenu is invoked.

This probably isn't perfect, but couldn't you add a MouseListener to the JPopupMenu?
Or you could extend JPopupMenu to extend one of the methods that are invoked upon popup: setVisible maybe, or menuSelectionChanged, or show? Or use a SelectionModel?
I'm just guessing, but those seem like solid places to start.
