Den Panel mit Pfeil-Tasten bewegen

[Matze]

Ich habe auch was gefunden:

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Panel1: TPanel;
    Button1: TButton;
    Button2: TButton;
  private
    { Private-Deklarationen }
    procedure CMDialogKey(var Msg: TWMKey); message CM_DIALOGKEY;
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.CMDialogKey(var Msg: TWMKEY);
var
  handled: Boolean;
begin
  handled := true;

  case msg.charcode of
    VK_UP: Panel1.Top := Panel1.Top - 10;
    VK_DOWN: Panel1.Top := Panel1.Top + 10;
    VK_LEFT: Panel1.Left := Panel1.Left - 10;
    VK_RIGHT: Panel1.Left := Panel1.Left + 10;
  else
    handled := False
  end;

  if handled then
    msg.result := 1
  else
    inherited;
end;

end.
