I haven't looked at your example code closely yet, but I would highly
recommend that you look into using UIManager instead of building the
menus manually.  UIManager offers a lot of advantages, including
easily defining a menu structure as an XML tree.  In addition, it
allows you to define menu items in terms of "Actions".  You can then
assign the same action to a toolbar button so that the Open item in
your menu and the Open button on your toolbar will do exactly the same
thing.  Because of this, you can then enable / disable these two
things together, and other things.  I've found it to be very easy to
use.  See this section in the tutorial for information:
