[Pascal Error] test_component.pas(43): E2037 Declaration of 'MouseUp' differs from previous declaration

Вот пишу компонент!

type
  tTest_component = class(TCustomControl)
  private
    { Private declarations }
    fChecked: boolean;
    fFont: tFont;
    fOnCheck, fOnDeCheck,
    fOnClick: tNotifyEvent;
    procedure setFont(const Value: tFont);
    procedure setCheckMarck(const Value: boolean);
  protected
    { Protected declarations }

    procedure paint; override;
  public
    { Public declarations }

  published
    { Published declarations }
    procedure Click; override; { работает }    
    procedure mouseUp; override; { не работает :mad: }

end;

Что делать, как объявить?

А F1 нажать ?

procedure MouseUp(Button: TMouseButton; Shift: TShiftState; X, Y: Integer); dynamic;

Прошу прощения, но:

type
  tTest_component = class(TCustomControl)
  private
    { Private declarations }
    fChecked: boolean;
    fFont: tFont;
    fOnCheck, fOnDeCheck,
    fOnClick: tNotifyEvent;
    isDown: boolean;
    procedure setFont(const Value: tFont);
    procedure setCheckMarck(const Value: boolean);
  protected
    { Protected declarations }

    procedure paint; override;
  public
    { Public declarations }

  published
    { Published declarations }
    procedure Click; override;

    procedure mouseUp(Button: TMouseButton; Shift: TShiftState; X, Y: Integer); dynamic;

    procedure onMouseEnter(var message: tMessage); message cm_mouseEnter;
    procedure onMouseLeave(var message: tMessage); message cm_mouseLeave;

    constructor create(aOwner: tComponent); override;
    destructor destroy; override;

    property Checked: boolean read fChecked write setCheckMarck;
    property Font: tFont read fFont write setFont;
    
    property onDeCheck: tNotifyEvent read fOnDeCheck write fOnDeCheck;
    property onClick: tNotifyEvent read fOnClick write fOnClick;
    property onCheck: tNotifyEvent read fOnCheck write fOnCheck;
end;

не действует! Не реагирует на событие компонент!

Прошу прощения! Я поменял "dinamic" на "override" и ща всё OK!
Спасибо!
