还是鼠标拖动操作的问题。

[goldcoast]

Label,Panel,Button,SpeedButton.在这些组件下如何用鼠标进行拖拉操作，并且可以显示出被选中组件的状态。最好给出源代码。我是初学者，希望各位大虾说详细点。谢谢了!

在控件的mousemove事件中调用上面过程
Procedure TMainFormF.StationMouseMove(Sender: TObject; Shift: TShiftState;
X, Y: Integer);
begin
ShiftStation((Sender as TControl), Shift, X, Y, 10);
end;
其中的奥秘自己慢慢体会吧，可以托动控件，可以改变控件得大小
对有些控件可能不管用

d6f9b(patriot)所说的功能不是我想要的。
我的意思是说，现在有几个Button按钮在窗体上，我用鼠标通过拉出个矩形框选择几个按钮，
比方说现在有五个按钮，我只想选中其中三个按钮，然后可以通过程序只对这几个我选择的按钮进行操作。

总之非常感谢以上的两位朋友。只有100分。那就三七开吧。
