Enclosing class:
JList
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. A future release of Swing will provide support for long term persistence.

Constructor Detail

JList.AccessibleJList

public JList.AccessibleJList()
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 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.
Overrides:
getAccessibleAt in class Container.AccessibleAWTContainer
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:
getAccessibleChild in class JComponent.AccessibleJComponent
Parameters:
i - zero-based index of child
Returns:
the nth Accessible child of the object

getAccessibleSelection

public AccessibleSelection getAccessibleSelection()
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:
this object

getAccessibleSelectionCount

public int getAccessibleSelectionCount()
Returns the number of items currently selected. If no items are selected, the return value will be 0.
Specified by:
getAccessibleSelectionCount in interface AccessibleSelection
Returns:
the number of items currently selected.

getAccessibleSelection

public Accessible getAccessibleSelection(int i)
Returns an Accessible representing the specified selected item in the object. If there isn't a selection, or there are fewer items selcted than the integer passed in, the return value will be null.
Specified by:
getAccessibleSelection in interface AccessibleSelection
Parameters:
i - the zero-based index of selected items
Returns:
an Accessible containing the selected item

isAccessibleChildSelected

public boolean isAccessibleChildSelected(int i)
Returns true if the current child of this object is selected.
Specified by:
isAccessibleChildSelected in interface AccessibleSelection
Parameters:
i - the zero-based index of the child in this Accessible object.
See Also:
AccessibleContext.getAccessibleChild(int)

addAccessibleSelection

public void addAccessibleSelection(int i)
Adds the specified selected item in the object to the object's selection. If the object supports multiple selections, the specified item is added to any existing selection, otherwise it replaces any existing selection in the object. If the specified item is already selected, this method has no effect.
Specified by:
addAccessibleSelection in interface AccessibleSelection
Parameters:
i - the zero-based index of selectable items

Removes the specified selected item in the object from the object's selection. If the specified item isn't currently selected, this method has no effect.
Specified by:
removeAccessibleSelection in interface AccessibleSelection
Parameters:
i - the zero-based index of selectable items

clearAccessibleSelection

public void clearAccessibleSelection()
Clears the selection in the object, so that nothing in the object is selected.
