  NAME
       XtPopdown, XtCallbackPopdown, MenuPopdown - unmap a pop-up

  SYNTAX
       void XtPopdown(popup_shell)
             Widget popup_shell;

       void XtCallbackPopdown(w, client_data, call_data)
             Widget w;
             XtPointer client_data;
             XtPointer call_data;

       void MenuPopdown(shell_name)
             String shell_name;

  ARGUMENTS
       call_data Specifies the callback data, which is not used by
                 this procedure.

       client_data
                 Specifies a pointer to the XtPopdownID structure.

       popup_shell
                 Specifies the widget shell to pop down.

       shell_name
                 Specifies the name of the widget shell to pop
                 down.

       w         Specifies the widget.

  DESCRIPTION
       The XtPopdown function performs the following:

       ⊕    Calls XtCheckSubclass to ensure popup_shell is a
            subclass of Shell.

       ⊕    Checks that popup_shell is currently popped_up;
            otherwise, it generates an error.

       ⊕    Unmaps popup_shell's window.

       ⊕    If popup_shell's grab_kind is either XtGrabNonexclusive
            or XtGrabExclusive, it calls XtRemoveGrab.

       ⊕    Sets pop-up shell's popped_up field to False.

       ⊕    Calls the callback procedures on the shell's
            popdown_callback list.

       The XtCallbackPopdown function casts the client data
       parameter to an XtPopdownID pointer:

       typedef struct {
            Widget shell_widget;
            Widget enable_widget;
       } XtPopdownIDRec, *XtPopdownID;
  The shell_widget is the pop-up shell to pop down, and the
  enable_widget is the widget that was used to pop it up.

       XtCallbackPopdown calls XtPopdown with the specified
       shell_widget and then calls XtSetSensitive to resensitize
       the enable_widget.

       If a shell name is not given, MenuPopdown calls XtPopdown
       with the widget for which the translation is specified.  If
       a shell_name is specified in the translation table,
       MenuPopdown tries to find the shell by looking up the widget
       tree starting at the parent of the widget in which it is
       invoked.  If it finds a shell with the specified name in the
       pop-up children of that parent, it pops down the shell;
       otherwise, it moves up the parent chain as needed.  If
       MenuPopdown gets to the application top-level shell widget
       and cannot find a matching shell, it generates an error.
