  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Button4: TButton;
    Button3: TButton;
procedure SetMousePos(x, y: longint) ;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button4Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
implementation
{$R *.dfm}

procedure TForm1.SetMousePos(x, y: longint) ;
var pt: TPoint;
begin
    pt := ClientToScreen(point(x, y)) ;
    SetCursorPos(pt.x, pt.y) ;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
SetCursorPos(0,0);    //absolute location
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
SetMousePos(0,0);   //relative location
end;

procedure TForm1.Button4Click(Sender: TObject);
begin
ShowCursor(False);  //hide mouse pointer within this window only, it is not systemwise.
end;

procedure TForm1.Button3Click(Sender: TObject);
begin
  ShowCursor(True); //show the mouse pointer
end;

end.
