Chapter 9: Event Dispatcher

What is the EventDispatch mechanism?

EventDispatch is a mechanism for responding to user events.

The basics:

• Event listeners encapsulate your event processing code.
• Event dispatcher notifies listeners of user events.
• Event objects contain information about the event.

5 types of event listeners.

EventListenerTouch - responds to touch events

EventListenerKeyboard - responds to keyboard events

EventListenerAcceleration - responds to accelerometer events

EventListenMouse - responds to mouse events

EventListenerCustom - responds to custom events
