From "Java in a Nutshell," from O'Reilly & Associates (a book everybody interested in Java programming should have, IMO, because it's both handy and cheap), the only menu-related that the AWT knows about is a MenuItem generating an ACTION_EVENT.  If I've understood your question correctly, the answer is thus no.

If what you really want to know is how you can make sure the right menu items are enabled or disabled, enable them or disable them as soon as this state becomes appropriate.  In other words, if one menu selection should cause another menu item to become disabled, disable it immediately upon receiving the first menu item's event.  You can then be assured that it will be disabled the next time this menu is displayed, unless of course you have re-enabled it.
