OnMouseEnter [Bitte helft mir!]

Meinst Du ein TImage?

[edit] Hab mal ein Beispiel erstellt mit einem Image und einem Label (hier die komplette Unit):

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TImage = class(ExtCtrls.TImage)
  private
    FOnMouseEnter: TNotifyEvent;
    FOnMouseLeave: TNotifyEvent;
    procedure CMMouseEnter(var Msg: TMessage);message CM_MOUSEENTER;
    procedure CMMouseLeave(var Msg: TMessage);message CM_MOUSELEAVE;
  public
    property OnMouseEnter: TNotifyEvent read FOnMouseEnter write FOnMouseEnter;
    property OnMouseLeave: TNotifyEvent read FOnMouseLeave write FOnMouseLeave;
  end;

  TForm1 = class(TForm)
    Image1: TImage;
    Label1: TLabel;
    procedure FormCreate(Sender: TObject);
  private
    { Private-Deklarationen }
    procedure DoOnEnter(Sender: TObject);
    procedure DoOnLeave(Sender: TObject);
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TImage.CMMouseEnter(var Msg: TMessage);
begin
  if Assigned(FOnMouseEnter) then
    FOnMouseEnter(self);
  Msg.Result := 0;
end;

procedure TImage.CMMouseLeave(var Msg: TMessage);
begin
  if Assigned(FOnMouseLeave) then
    FOnMouseLeave(self);
  Msg.Result := 0;
end;

procedure TForm1.DoOnEnter(Sender: TObject);
begin
  Label1.Caption := 'drin';
end;

procedure TForm1.DoOnLeave(Sender: TObject);
begin
  Label1.Caption := 'draußen';
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Image1.OnMouseEnter := DoOnEnter;
  Image1.OnMouseLeave := DoOnLeave;
end;

end.
