Class MouseDriver

java.lang.Object
  javax.usb.examples.MouseDriver

public class MouseDriver
extends Object

Example driver for USB mice.

This shows how to get events from a USB mouse. This class should not be used except by other example code.

WARNING : The code in the class is intended for example use only! Some functionality (e.g. HID usage detection) is simplified for example purposes, and should not be reproduced in non-example code. Also this code is designed to be example code, not robust well-written code, and so the design should not be duplicated in normal code.
