protected class JList.AccessibleJList
extends JComponent.AccessibleJComponent
implements AccessibleSelection, PropertyChangeListener, ListSelectionListener, ListDataListener

This class implements accessibility support for the JList class. It provides an implementation of the Java Accessibility API appropriate to list user-interface elements.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.

Constructor Details

AccessibleJList

public AccessibleJList()

Constructs an AccessibleJList.

Method Details

propertyChange

public void propertyChange(PropertyChangeEvent e)

Property Change Listener change method. Used to track changes to the DataModel and ListSelectionModel, in order to re-set listeners to those for reporting changes there via the Accessibility PropertyChange mechanism.

Specified by:

propertyChange in interface PropertyChangeListener

Parameters:

e - PropertyChangeEvent

valueChanged

public void valueChanged(ListSelectionEvent e)

List Selection Listener value change method. Used to fire the property change

Specified by:

valueChanged in interface ListSelectionListener

Parameters:

e - ListSelectionEvent

intervalAdded

public void intervalAdded(ListDataEvent e)

List Data Listener interval added method. Used to fire the visible data property change

Specified by:

intervalAdded in interface ListDataListener

Parameters:

e - ListDataEvent

intervalRemoved

public void intervalRemoved(ListDataEvent e)

List Data Listener interval removed method. Used to fire the visible data property change

Specified by:

intervalRemoved in interface ListDataListener

Parameters:

e - ListDataEvent

contentsChanged

public void contentsChanged(ListDataEvent e)

List Data Listener contents changed method. Used to fire the visible data property change

Specified by:

contentsChanged in interface ListDataListener

Parameters:

e - ListDataEvent

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()

Get the state set of this object.

Overrides:

getAccessibleStateSet in class JComponent.AccessibleJComponent

Returns:

an instance of AccessibleState containing the current state of the object

See Also:

• AccessibleState

getAccessibleRole

public AccessibleRole getAccessibleRole()

Get the role of this object.

Overrides:

getAccessibleRole in class JComponent.AccessibleJComponent

Returns:

an instance of AccessibleRole describing the role of the object

See Also:

• AccessibleRole

getAccessibleAt

public Accessible getAccessibleAt(Point p)

Returns the Accessible child contained at the local coordinate Point, if one exists. Otherwise returns null.

Specified by:

getAccessibleAt in interface AccessibleComponent

Overrides:

getAccessibleAt in class Container.AccessibleAWTContainer

Parameters:

p - the point defining the top-left corner of the Accessible, given in the coordinate space of the object's parent

Returns:

the Accessible at the specified location, if it exists

getAccessibleChildrenCount

public int getAccessibleChildrenCount()

Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.

Overrides:

getAccessibleChildrenCount in class JComponent.AccessibleJComponent

Returns:

the number of accessible children in the object.

getAccessibleChild

public Accessible getAccessibleChild(int i)

Return the nth Accessible child of the object.

Overrides:

Get the AccessibleSelection associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleSelection interface on behalf of itself.

Overrides:

getAccessibleSelection in class AccessibleContext

Returns:
