XtWindowToWidget()														XtWindowToWidget()

Name
  XtWindowToWidget - translate a window and display pointer into a widget ID.

Synopsis
  Widget XtWindowToWidget(display, window)
	 Display *display;
	 Window window;

Inputs
  display   Specifies the display on which the window is defined.

  window    Specifies the window for which you want the widget.

Returns
  The widget that created window on display, or NULL.

Description
  XtWindowToWidget()  takes a display pointer and a window and returns the associated widget ID.  The widget must be within the same applica-
  tion as the caller.

  If the specified display and window do not match any widget created by the application, XtWindowToWidget() returns NULL.

Usage
  This function can be useful to convert the window of an XEvent structure into the corresponding widget.  If you use the standard Intrinsics
  event dispatching mechanisms, however, this should not ever be necessary.
