Package com.sun.java.accessibility.util

package com.sun.java.accessibility.util

Provides a collection of interfaces and classes that compose the Java Accessibility Utilities. The classes are used by Assistive Technologies, such as the screen readers which are used by those who are blind, and help provide access to GUI toolkits that implement the Java Accessibility API. An overview of the important classes follows.

The class AccessibilityEventMonitor implements a PropertyChange listener on every UI object that implements interface Accessible in the Java Virtual Machine.

The class AWTEventMonitor implements a suite of listeners that are conditionally installed on every AWT component instance in the Java Virtual Machine.

The class EventQueueMonitor provides key core functionality for Assistive Technologies (and other system-level technologies that need some of the same things that Assistive Technology needs).

The class GUIInitializedMulticaster is used to maintain a list of GUIInitializedListener classes which are used by the EventQueueMonitor class to notify an interested party when the GUI subsystem has been initialized. Note that this class is intended to be used primarily for internal support in the EventQueueMonitor class, and is not intended to be used by classes outside the Java Accessibility Utility package.

The class SwingEventMonitor extends AWTEventMonitor by adding a suite of listeners conditionally installed on every Swing component instance in the Java Virtual Machine.

The class TopLevelWindowMulticaster is used to maintain a list of TopLevelWindowListener classes which are used by the EventQueueMonitor class to notify an interested party when a top level window is created or destroyed in the Java Virtual Machine Note that this class is intended to be used primarily for internal support in the EventQueueMonitor class, and is not intended to be used by classes outside the Java Accessibility Utility package.

The class Translator provides a translation to interface Accessible for objects that do not implement interface Accessible.

Class	Description
AccessibilityEventMonitor	AccessibilityEventMonitor implements a PropertyChange listener on every UI object that implements interface Accessible in the Java Virtual Machine.
AccessibilityListenerList	The AccessibilityListenerList is a copy of the Swing EventListerList class.
AWTEventMonitor	The AWTEventMonitor implements a suite of listeners that are conditionally installed on every AWT component instance in the Java Virtual Machine.
EventID	EventID contains integer constants that map to event support in AWT and Swing.
EventQueueMonitor	The EventQueueMonitor class provides key core functionality for Assistive Technologies (and other system-level technologies that need some of the same things that Assistive Technology needs).
GUIInitializedListener	The GUIInitializedListener interface is used by the EventQueueMonitor class to notify an interested party when the GUI subsystem has been initialized.
SwingEventMonitor	SwingEventMonitor extends AWTEventMonitor by adding a suite of listeners conditionally installed on every Swing component instance in the Java Virtual Machine.
TopLevelWindowListener	The TopLevelWindowListener interface is used by the EventQueueMonitor class to notify an interested party when a top level window is created or destroyed in the Java Virtual Machine.
Translator	The Translator class provides a translation to interface Accessible for objects that do not implement interface Accessible.
