protected class JList.AccessibleJList extends JComponent.AccessibleJComponent implements AccessibleSelection, PropertyChangeListener, ListSelectionListener, ListDataListener
This class implements accessibility support for theJList
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 JavaBeansTM has been added to the
java.beans
package. Please seeXMLEncoder

Method Detail
-
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 interfacePropertyChangeListener

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 interfaceListDataListener
- 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 interfaceListDataListener
- 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 interfaceListDataListener
- Parameters:
e
- ListDataEvent
-
getAccessibleStateSet
public AccessibleStateSet getAccessibleStateSet()
Get the state set of this object.- Overrides:
getAccessibleStateSet
in classJComponent.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 classJComponent.AccessibleJComponent

, 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:
