The SimpleMenu widget is a container for the menu entries.  It is a
direct subclass of shell, and is should be created with
<function>XtCreatePopupShell</function>, not <xref linkend='XtCreateManagedWidget' xrefstyle='select: title'/>.  This is the
only part of the menu that
actually is associated with a window.  The SimpleMenu serves as the glue to bind
the individual menu entries together into a menu.

If popup menus are desired it will be necessary to add the

translation table of the widget that will be popping up the menu.  The
<function>MenuPopup</function> action is described in <emphasis remap='I'>(xT</emphasis>.
<function>XawPositionSimpleMenu</function> is a global action procedure registered by
the SimpleMenu widget when the first one is created or the convenience

will continue up the widget tree using each of the invoking widget's
ancestors as the reference widget.  If it is still unsuccessful it will
print a warning message and give up.  <function>XawPositionSimpleMenu</function> will
position the menu directly under the pointer cursor.  The menu will be
placed so that the pointer cursor is centered on the entry named by the
