I wan to access the group name libros items to add evenListeners to  
them.

I have this code to access the main ones on the menuBar.


  protected function init():void{

  var mbiBlog:MenuBarItem= mBar.menuBarItems[4] as MenuBarItem;
  mbiBlog.addEventListener(MouseEvent.CLICK, openWindowBlog);
  var mbiAntiguoT:MenuBarItem = mBar.menuBarItems[3].root[1] as  
MenuBarItem;// I've been trying to access the sub-Items I really don't  
know how, some help please.
  mbiAntiguoT.addEventListener(MouseEvent.CLICK, windowBibliaAntigua);

  }
