XtPopdown()															       XtPopdown()

Name
  XtPopdown - unmap a popup shell.

Synopsis
  void XtPopdown(popup_shell)
	 Widget popup_shell;

Inputs
  popup_shell
	    Specifies the widget shell to pop down.

Description
  XtPopdown()	   pops      down     a     popup     shell	and	calls	  the	  functions	registered     on     the     shell's
  XtNpopdownCallback list.  The "Algorithm" section below explains the details of this process.

Usage
  The Intrinsics also provide other convenience routines to pop down a popup shell.  To perform a pop down from a callback list, register the
  function XtCallbackPopdown().  To do so from a translation table, use the action XtMenuPopdown.

  Popup  shell widgets can be created with XtCreatePopupShell(), and can be popped up with XtPopup() or XtPopupSpringLoaded(), or with one of
  the built-in callback functions (XtCallbackExclusive(),  XtCallbackNonexclusive(),  or  XtCallbackNone()),  or  with	the  built-in  action
  XtMenuPopup.

Algorithm
  XtPopdown() performs the following:

  o  Calls XtCheckSubclass() to ensure popup_shell's class is a subclass of shellWidgetClass.

  o  Checks that the popped_up field of popup_shell is True; otherwise, it returns immediately.

  o  Unmaps  popup_shell's  window  and,  if override_redirect is False, sends a synthetic UnmapNotify event as specified by the Inter-Client
     Communications Conventions Manual.

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

  o  Sets popup_shell's popped_up field to False.

  o  Calls the callback procedures on the shell's popdown_callback list, specifying a pointer to the value of the shell's grab_kind field  as
     the call_data argument.

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 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:

       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 spec-
       ified 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.
