 * Event is the base class for all event classes.

 * It encapsulates the parameters associated with an event.
 * The {@link sender} property describes who raises the event.
 * And the {@link handled} property indicates if the event is handled.
 * If an event handler sets {@link handled} to true, those handlers
 * that are not invoked yet will not be invoked anymore.
