I would like to have the following widget structure:

    +--------------------------------------------------+
    + pane                                             +
    +                                                  +
    +   +------------------------------------------+   +
    +   + box1                                     +   +
    +   +                                          +   +
    +   +  +---------+  +------------ +            +   +
    +   +  + command +  + simpleMenu  +            +   +
    +   +  +         +  +             +            +   +
    +   +  +         +  + +---------+ +            +   +
    +   +  +         +  + + smeLine + +            +   +
    +   +  +         +  + +---------+ +            +   +
    +   +  +         +  + +---------+ +            +   +
    +   +  +         +  + + smeBSB  + +  ...etc... +   +
    +   +  +         +  + +---------+ +            +   +
    +   +  +         +  +             +            +   +
    +   +  +         +  +  ...etc...  +            +   +
    +   +  +         +  +             +            +   +
    +   +  +---------+  +-------------+            +   +
    +   +                                          +   +
    +   +------------------------------------------+   +
    +                                                  +
    +   +------------------------------------------+   +
    +   + box2                                     +   +
    +   +------------------------------------------+   +
    +                                                  +
    +   +------------------------------------------+   +
    +   + box3                                     +   +
    +   +------------------------------------------+   +
    +                                                  +
    +                    ...etc...                     +
    +--------------------------------------------------+

That is, a panedWidget containing several boxWidgets, which in turn
contain some number of commandWidgets and simpleMenus inside of them.

There are two problems:

(1) If I create this structure in a depth-first order (ie, pane, box1,
command, simpleMenu, smeLine, smeBSB, box2, box3) then the panedWidget
gets confused about sizes of box1, box2, and box3.  the only way i
have found that can create this structure correctly is to create the
menus AFTER everything else is in place.

(2) To complicate things, I would like different subsets of
box1..box<n> to be displayed at different times.  I've been trying to
do this by calling XtUnmanageChild and XtManageChild on the
appropriate boxes.  This works ok, except that the panedWidget gets
re-confused about the height of the boxes.

(3) Finally, I would like to be able to add and remove menu entries on
the fly and keep the panedWidget happy.


All of this is happening on a PMax running Mach, under X11R4 (I don't
know what bug fixes have been installed).

any suggestions?
