Has anyone sucessfully done this?  I have yet to hear of a working
implementation.

The simple menu entries (sme<something>ObjectClass) are not widgets, but non
windowed objects.  As such they have no translation or event management of their
own.  This is one of the reasons I think that objects are a bad idea, they
detract from the nice modular design of Xt.  "Then why did you use them?", I
hear you cry...  My major goal behind the Simple Menu widget was to make it fast
to pop up and down.  I felt that if the menus felt sluggish then they would not
be used.  I think I was able to get the feel that I wanted, but unfortunately I
had to sacrafice some of the nice things Xt gives to all widgets.

Is there any way to implement cascading menus?  I cannot think of one, short of
whacking the Simple menu code.
