Try this:

procedure TForm1.AddTab(AFileName: String);
var
   Sheet: TTabSheet;
   Ed: TSynEdit;
begin
   Sheet := TTabSheet.Create(pagecontrol1);
   sheet.Parent := PageControl1;
   Sheet.Caption := 'Unnamed';
   Ed := TSynEdit.Create(Sheet);
   ed.Parent := Sheet;
   ed.BoundsRect := sheet.BoundsRect;
   ed.LineText := 'specimen line';
   PageControl1.ActivePage := Sheet;
end;
