Class AccessibilityEventMonitor

java.lang.Object

com.sun.java.accessibility.util.AccessibilityEventMonitor

public class AccessibilityEventMonitor
extends Object

AccessibilityEventMonitor implements a PropertyChange listener on every UI object that implements interface Accessible in the Java Virtual Machine. The events captured by these listeners are made available through listeners supported by AccessibilityEventMonitor. With this, all the individual events on each of the UI object instances are funneled into one set of PropertyChange listeners.

This class depends upon EventQueueMonitor, which provides the base level support for capturing the top-level containers as they are created.
