     XtPopdown(3Xt)	X Version 11 (Release 6.6)	XtPopdown(3Xt)

     NAME
	  XtPopdown, XtCallbackPopdown - 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:

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

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

	  o    Unmaps popup_shell's window.

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

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

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

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

     XtPopdown(3Xt)	X Version 11 (Release 6.6)	XtPopdown(3Xt)

	  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.
