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


       #include <Xm/RowColumn.h>

       void XmAddToPostFromList(
       Widget menu,
       Widget post_from_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

       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

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

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