Class InputEventHandler

java.lang.Object
  java.lang.Thread
      ch.claudio.pen.input.InputEventHandler

All Implemented Interfaces:

java.lang.Runnable

public class InputEventHandler
extends java.lang.Thread

Receive data from an EventReader and aggregate them as needed.

The input device delivers separate events for X and Y changes, but adds an EV_SYN after events belonging together. This allows it to combine them.

For this to work an extra thread is necessary, as unfortunately Java does not allow to select on FileChannels.
