TabSheetCaption (Delphi)

Description

This example requires a TPageControl populated by several TabSheets, a TEdit, and a TButton. When the button is clicked, the caption of the active tab changes to that of the TEdit.

These lines of code could also be written:

  PageControl1.ActivePage.Caption := Edit1.Text;

This would preclude the need for a TTabSheet variable, since PageControl1.ActivePage is already of type TTabSheet.

Code

procedure TForm1.Button1Click(Sender: TObject);
var
  sheet: TTabSheet;

begin
  sheet := PageControl1.ActivePage;
  sheet.Caption := Edit1.Text;
end;
