XmAddToPostFromList — a RowColumn function that makes a menu accessible from more than one widget

XmAddToPostFromList makes a menu accessible from more than one widget. After a menu is once created, this
       function may be used to make that menu accessible from a second  widget.  The  process  may  be  repeated
       indefinitely. In other words, where an application would use XmCreatePopupMenu or XmCreatePulldownMenu or
       their  equivalent  to create a new menu identical to one that already exists, it can use this function to
       reuse that earlier menu.

       If menu refers to a Popup menu, then the post_from_widget widget can now pop up the specified  menu.  The
       actual  posting  of  the menu occurs as it always does, either through an event handler, or the automatic
       popup menu support (see the XmRowColumn(3) reference page).

       If menu refers to a Pulldown menu, its ID is  placed  in  the  XmNsubMenuId  resource  of  the  specified
       post_from_widget.   In  this  case,  the  post_from_widget  widget  must  be  either a CascadeButton or a
       CascadeButtonGadget.

       Note that this function manipulates the internal structures themselves, not a copy of them.

       menu      Specifies the ID of the RowColumn widget containing the menu (Popup or  Pulldown)  to  be  made
                 accessible from the widget.

       post_from_widget
                 Specifies  the  widget  ID  of  the widget which will now be able to post the menu specified by
                 menu.
