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;
           caddr_t client_data;
           caddr_t 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.
