Kann ich Windows-Messagehandler einer Form auslagern?

[sirius]

Delphi-Quellcode:

TWindowsMessageHandler = class
    private
       procedure WMEnterSizeMove(var Message:TWMSize); message WM_ENTERSIZEMOVE;
       procedure WMExitSizeMove(var Message:TWMSize); message WM_EXITSIZEMOVE;
       [...]         
    public
       procedure handleMessage(var Message: TMessage);
end; 


procedure TWindowsMessageHandler.handleMessage(var Message: TMessage);
begin
  dispatch(message);
end;

sollte tun
