Comentarios

Cuando se crea un delegado InputLanguageChangedEventHandler, se identifica el método que controlará el evento. Para asociar el evento al controlador, se debe agregar una instancia del delegado al evento. Siempre que se produce el evento, se llama a su controlador, a menos que se quite el delegado.

Para obtener más información sobre los delegados del controlador de eventos, vea Control y generación de eventos.
