QPropertyChangeHandler<Functor> se crea al registrar un callback en un QProperty para escuchar cambios en el valor de la propiedad, usando QProperty::onValueChanged y QProperty::subscribe. Mientras el manejador de cambios esté vivo, el callback permanece instalado.
Una instancia de manejador puede ser transferida entre ámbitos C++ usando la semántica move.
