Detailed Description

Simple listener for JoyStick events.

The JoyStickListener gets called each time an event is received from the JoyStick. By default, there is no listener, and users can just asynchronously query the JoyStick for its current internal state. If those queries come in too slowly, however, they may miss some events (e.g., a briefly pressed button). So, production code should define a derived class for JoyStickListener and register it with the JoyStick object, so that it will take action as soon as an event is received.
