Class com.sun.java.accessibility.util.AWTEventMonitor

java.lang.Object
   |
   +----com.sun.java.accessibility.util.AWTEventMonitor

public class AWTEventMonitor

extends Object

The AWTEventMonitor implements a suite of listeners that are conditionally installed on every AWT component instance in the Java Virtual Machine. The events captured by these listeners are made available through a unified set of listeners supported by AWTEventMonitor. With this, all the individual events on each of the AWT component instances are funnelled into one set of listeners broken down by category (see EventID for the categories).

This class depends upon EventQueueMonitor, which provides the base level support for capturing the top-level containers as they are created. In order for this to happen, the EventQueueMonitor class needs to be in the CLASSPATH environment variable and the following line needs to be in the awt.properties file:

 AWT.EventQueueClass=com.sun.java.accessibility.util.EventQueueMonitor
