  32  * AccEventListener is the general event listener for all top windows. The top windows defined
  33  * in UNO are: FRAME, WINDOW, DIALOG, MENU, TOOLTIP.
  34  * It implements the methods of XTopWindowListener and the most important method is windowOpened().
  35  * In this method, all the accessible objects (including COM object and Uno objects) are created and
  36  * cached into bridge managers, and they are monitored by listeners for later accessible event handling.
