[flexcoders] Overriding the mouseClickHandler in DataGrid

[Cato Paus]

Hi Alex, do you have a better suggestion?
                
override protected function mouseClickHandler(event:MouseEvent):void
{
  var pattern:RegExp = /DataGridHeader/;
  var test:String = String(event.target);
     if(pattern.test(test)){
        var r:IListItemRenderer;
            r = mouseEventToItemRenderer(event);
         if(r)
         {
           super.mouseClickHandler(event);
         }
         else
         {
           clearSelected(true);
           dispatchEvent(new ListEvent(ListEvent.CHANGE));
           event.stopImmediatePropagation();
        }
      }
}
