有两个和克隆相关的方法: Clone()、CloneChildFromStream().
Clone() 很好用, 但 CloneChildFromStream() 的源码很明显地写错了(是小问题, 谁外语好去报一下).
procedure TForm1.FormCreate(Sender: TObject); var i: Integer; begin for i := 0 to 9 do ListBox1.Items.Add('Item' + IntToStr(i)); end; {把 ListBox1 克隆到 Panel1} procedure TForm1.Button1Click(Sender: TObject); begin Panel1.AddObject(ListBox1.Clone(Self)); end;
