[DeddyH]

Kleines Beispiel (nur ein Formular mit einem Panel):

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TPanel = class(ExtCtrls.TPanel)
  published
    property OnKeyPress;
  end;

  TForm1 = class(TForm)
    Panel1: TPanel;
    procedure FormCreate(Sender: TObject);
  private
    { Private-Deklarationen }
    procedure PanelKeyPress(Sender: TObject; var Key: char);
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

{ TForm1 }

procedure TForm1.FormCreate(Sender: TObject);
begin
  Panel1.OnKeyPress := PanelKeyPress;
  ActiveControl := Panel1;
end;

procedure TForm1.PanelKeyPress(Sender: TObject; var Key: char);
begin
  ShowMessage(Key);
end;

end.
