XtCallbackPopdown()													       XtCallbackPopdown()

Name
  XtCallbackPopdown - callback function to popdown a widget.

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

Inputs
  w	    Specifies the widget.

  client_data
	    Specifies a pointer to an XtPopdownID structure.

  call_data Specifies the callback data, which is not used by this procedure.

Description
  XtCallbackPopdown() casts is client_data argument to an XtPopdownIDRec *, calls XtPopdown on the widget in the shell_widget field, and then
  resensitizes the widget in the enable_widget field by calling XtSetSensitive().

  XtCallbackPopdown() is a convenience procedure designed to be registered on a widget's callback list (which is why  it  has  third,  unused
  argument) and used on a shell widget popped up with XtCallbackExclusive(), XtCallbackNone(), or XtCallbackNonexclusive().  The widget to be
  popped down and the widget that was desensitized when the shell was popped up should be stored into the XtPopdownID structure that is  reg-
  istered with XtCallbackPopdown().

Usage
  It is also possible to pop down a shell with the XtMenuPopdown action.

Example
  The  following  code	registers XtCallbackPopdown() to popdown the widget pshell when the button ok is pressed.  It assumes that pshell was
  popped up by XtCallbackExclusive() registered on the widget button.

     XtPopdownIDRec pop_rec;

     pop_rec.shell_widget = pshell;
     pop_rec.enable_widget = button;
     XtAddCallback(ok, XtNcallback, XtCallbackPopdown, &pop_rec);

Structures
  XtCallbackPopdown() expects a XtPopdownID as its client_data argument.

     typedef struct {
	 Widget shell_widget;
	 Widget enable_widget;
     } XtPopdownIDRec, *XtPopdownID;
