  TMyApplication = class(TBrowserApplication)
    procedure doRun; override;
       public
     FMyPage: TWebPage;
     FMyButton: TButtonWidget;
   end;
procedure TMyApplication.doRun;
var
  datum: TDateTime;

begin

  FMyPage:=TWebPage.Create(Self);

FMyButton:=TButtonWidget.Create(Self);
FMyButton.Parent:=FMyPage;
FMyButton.Text:='Start The code';
  FMyPage.Refresh;
