/**
 * AccEventListener is the general event listener for all top windows. The top windows defined
 * in UNO are: FRAME, WINDOW, DIALOG, MENU, TOOLTIP.
 * It implements the methods of XTopWindowListener and the most important method is windowOpened().
 * In this method, all the accessible objects (including COM object and Uno objects) are created and
