{ This code shows how to clone a TPanel (Panel1) 
  You can do it with any other component 

  Dieser Code zeigt, wie ein TPanel (Panel1) geklont 
  werden kann. Das funktioniert naturlich auch mit 
  anderen Komponenten 
}

 procedure TForm1.Button1Click(Sender: TObject);
 var
   ms: TMemoryStream;
   s: string;
   p, temp: TPanel;
   x,y: Integer;
 begin
   ms := TMemoryStream.Create;
   try
     temp := panel1;
     s := panel1.Name;
     panel1.Name := '';
     try
       ms.WriteComponent(temp);
       ms.Position := 0;
       p := TPanel.Create(Self);
       ms.ReadComponent(p);
       with p do
       begin
         x := panel1.Left;
         y := panel1.Top;
         Inc(x, 5);
         Inc(y, 5);
         SetBounds(x, y, Width, Height);
         Parent := Self;
         Name := Format('Panel%d_%d', [x, y]);
       end;
     finally
       temp.Name := s;
       panel1 := temp;
     end
   finally
     ms.Free;
   end; { finally }
 end;
