  TForm1 = class(TForm)
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1MouseMove(Sender: TObject; Shift: TShiftState; X,
      Y: Integer);

  public
    { Public declarations }
  end;var
  Form1: TForm1;implementation{$R *.DFM}procedure TForm1.FormCreate(Sender: TObject);
VAr
  Button2: TButton;
  Button3: TButton;
  Button4: TButton;
begin
  button2:=tbutton.create(nil);
  button3:=tbutton.create(nil);
  button4:=tbutton.create(nil);
  button2.Parent:=form1;
  button3.parent:=form1;
  button4.parent:=form1;
  button2.left:=100;
  button2.top:=100;
  button3.left:=100;
  button3.top:=200;
  button4.left:=100;
  button4.top:=300;
  button2.Caption:='dfasdf2';
  button3.Caption:='dfasdf3';
  button4.Caption:='dfasdf4';
  button2.OnMouseMove:=button1.OnMouseMove;
  button3.OnMouseMove:=button1.OnMouseMove;
  button4.OnMouseMove:=button1.OnMouseMove;
end;procedure TForm1.Button1MouseMove(Sender: TObject; Shift: TShiftState; X,
  Y: Integer);
var
 i:integer;
begin
 for i:=0 to ComponentCount-1 do
    if Components[i] is TBUTTON then
       tbutton(Components[i]).font.size:=8;
 tbutton(sender).font.size:=12;
end;end.
