automatisch Element mit focus auswählen

[DeddyH]

Schau Dir mal dieses Beispiel an (alle Buttons haben denselben Handler):

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls, ExtCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    Button4: TButton;
    Label1: TLabel;
    Timer1: TTimer;
    procedure Button1Click(Sender: TObject);
    procedure Timer1Timer(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;


implementation

{$R *.DFM}

procedure TForm1.Button1Click(Sender: TObject);
begin
  Label1.Caption := TControl(Sender).Name;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  if (ActiveControl is TButton) then
    TButton(ActiveControl).Click;
end;

end.

Das entspricht somit exakt dem, was ich unter #2 bereits gepostet habe.
