   I wondered about this sort of thing when I saw the same quote in
the manual.  It's nice how they tell you that you can add one, but then
offer nary a clue to help you do so.  Pretty lame, by my standards :-(

   Here are a few lines, copped from an application I'm writing, that
add a form widget as a "WorkArea" to an XmFileSelectionBox :


    n = 0;
    fileW = XmCreateFileSelectionBox(parent, "fileW", args, n);
    XtManageChild(fileW);

    n = 0;
    form = XmCreateForm(fileW, "form", args, n);
    XtManageChild(form);


   This works just fine (later on I add stuff to the form widget, so it
actually has some non-zero size, but that is irrelevant to the problem).
