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:

       o    Calls XtCheckSubclass to ensure popup_shell is a sub-
	    class of Shell.

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

       o    Unmaps popup_shell's window.

       o    If popup_shell's grab_kind is either XtGrabNonexclu-
	    sive 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 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.
