想写一个TShape的控件,当Shape是圆时,鼠标移到圆上光标才变成手。大家帮帮忙。该如何处理

想写一个TShape的控件,当Shape是圆时,鼠标移到圆上光标才变成手。大家帮帮忙。
TShape的控件,设置了Cursor为crHandPoint。当Shape是圆时,鼠标移到设计时的方形上,鼠标就已经变成手,我想做一个鼠标移到圆上光标才变成手的控件。该怎么做?
各位,请帮帮忙。

------解决方案--------------------
动态设定不可以吗?
在TShape的OnMouseMove事件中加上
Delphi(Pascal) code

Shape1.Cursor := crHandPoint;

------解决方案--------------------
Delphi(Pascal) code

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  ExtCtrls, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    Panel1: TPanel;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
begin
  Panel1.Color := clRed;
  Panel1.Cursor := crHandPoint;
  Panel1.SetBounds(50, 80, 100, 100);
  Panel1.BevelOuter := bvNone;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  region: THandle;
begin
  region := CreateEllipticRgn(0, 0, 100, 100);
  SetWindowRgn(Panel1.Handle, region, True);
end;

end.
