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.
