    protected void OnDeleteEvent (object sender, DeleteEventArgs a)
   {
      Application.Quit  ();
       a.RetVal = true;
   }
    protected   void OnButton1Clicked (object sender, EventArgs e)
   {
      ((Button)sender).Label    = "Clicked";
      Button newButton = new Button ();
       newButton.Label = "New Button";
       newButton.Clicked += new EventHandler (newButton_Click);
     //show new created button on screen
      fixed1.Show ();
       fixed1.Add (newButton);
