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.
