XtPopdown(3)			 XT FUNCTIONS			  XtPopdown(3)

NAME
       XtPopdown, XtCallbackPopdown - unmap a pop-up

SYNTAX
       void XtPopdown(Widget popup_shell);

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

       void MenuPopdown(String shell_name);

ARGUMENTS
       call_data Specifies the callback	data, which is not used	by this	proce-
		 dure.

       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 gen-
	    erates 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:

       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 wid-
       get for which the translation is	specified.  If a shell_name is speci-
       fied 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 ap-
       plication top-level shell widget	and cannot find	a matching shell, it
       generates an error.
