RE: How to create submenus using UIManager

["Stewart Weiss" <stewart weiss acm org>]

This just creates the menubar with the pull-down menus for the 
File and Edit menus. That much I know. But I am trying to creating
submenus of the pull-down menus, and nothing I have tried works.
For example, like in a View menu, suppose I want a menu item 
labelled "Toolbars" that brings up a menu with various toolabrs in it.

I have Emmanuele Bassi's recent-uimanager code and I am trying
to use that as a guide, but it seems absurd to have to go down so
far as to create GObjects just to do this.
