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.

Field Summary

`protected static final AccessibilityListenerList`	`listenerList`	The current list of registered `PropertyChangeListener` classes.

Constructor Summary

Constructor	Description
`AccessibilityEventMonitor()`	Constructs an `AccessibilityEventMonitor`.

Method Summary

Modifier and Type	Method	Description
`static void`	`addPropertyChangeListener(PropertyChangeListener l)`	Adds the specified listener to receive all PropertyChange events on each UI object instance in the Java Virtual Machine as they occur.
`static void`	`removePropertyChangeListener(PropertyChangeListener l)`	Removes the specified listener so it no longer receives PropertyChange events when they occur.

Methods declared in class Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Modifier and Type	Method	Description
`protected Object`	`clone()`	Creates and returns a copy of this object.
`boolean`	`equals(Object obj)`	Indicates whether some other object is "equal to" this one.
`protected void`	`finalize()`	Deprecated, for removal: This API element is subject to removal in a future version. Finalization is deprecated and subject to removal in a future release.
`final Class<?>`	`getClass()`	Returns the runtime class of this `Object`.
`int`	`hashCode()`	Returns a hash code value for this object.
`final void`	`notify()`	Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()`	Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()`	Returns a string representation of the object.
`final void`	`wait()`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
`final void`	`wait(long timeoutMillis)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis, int nanos)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Method Details

addPropertyChangeListener

public static void addPropertyChangeListener(PropertyChangeListener l)

Adds the specified listener to receive all PropertyChange events on each UI object instance in the Java Virtual Machine as they occur.

Note: This listener is automatically added to all component instances created after this method is called. In addition, it is only added to UI object instances that support this listener type.

Parameters:

l - the listener to add

removePropertyChangeListener

public static void removePropertyChangeListener(PropertyChangeListener l)

Removes the specified listener so it no longer receives PropertyChange events when they occur.

Parameters:

l - the listener to remove
