XtPopdown(3Xt)		   XT FUNCTIONS		   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 struc
		 ture.

       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 sub
	    class of Shell.

	   Checks that popup_shell is currently popped_up; oth
	    erwise, it generates an error.

	   Unmaps popup_shell's window.

	   If popup_shell's grab_kind is either XtGrabNonexclu_
	    sive or XtGrabExclusive, it calls XtRemoveGrab.

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

	   Calls the callback procedures on the shell's pop
	    down_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 wid
       get 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.
