4. Using Signal Events
The signal event is intended for use in situations where a single event needs to be propagated to multiple event handlers. In this case the event handlers are signalable objects which implement the Signalable interface. This chapter examines signal events in more detail and introduces the concept of signal event objects which are used for managing signal propagation to signalable event handlers.
