Class JList.AccessibleJList
- All Implemented Interfaces:
- PropertyChangeListener,- Serializable,- EventListener,- AccessibleComponent,- AccessibleExtendedComponent,- AccessibleSelection,- ListDataListener,- ListSelectionListener
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.

- propertyChangein interface- PropertyChangeListener
- Parameters:
- e- PropertyChangeEvent
 
- 
valueChangedList Selection Listener value change method. Used to fire the property change- Specified by:
- valueChangedin interface- ListSelectionListener
- Parameters:
- e- ListSelectionEvent
 
- 
intervalAddedList Data Listener interval added method. Used to fire the visible data property change- Specified by:
- intervalAddedin interface- ListDataListener
- Parameters:
- e- ListDataEvent
 
- 
intervalRemovedList Data Listener interval removed method. Used to fire the visible data property change- Specified by:
- intervalRemovedin interface- ListDataListener
- Parameters:
- e- ListDataEvent
 
- 
contentsChangedList Data Listener contents changed method. Used to fire the visible data property change- Specified by:
- contentsChangedin interface- ListDataListener

- getAccessibleStateSetin class- JComponent.AccessibleJComponent
- Returns:
- an instance of AccessibleState containing the current state of the object
- See Also:
 
- 
getAccessibleRoleGet the role of this object.- Overrides:
- getAccessibleRolein class- JComponent.AccessibleJComponent

- an instance of AccessibleRole describing the role of the object
- See Also:
 
- 
getAccessibleAtReturns theAccessiblechild contained at the local coordinatePoint, if one exists. Otherwise returnsnull.- Specified by:
- getAccessibleAtin interface- AccessibleComponent
- Overrides:
- getAccessibleAtin 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 Accessibleat the specified location, if it exists
 
- 
getAccessibleChildrenCountpublic 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:
- getAccessibleChildrenCountin class- JComponent.AccessibleJComponent
- Returns:

getAccessibleSelectionGet 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:
- getAccessibleSelectionin class- AccessibleContext
- Returns:
- this object
- See Also:
 
- 
getAccessibleSelectionCountpublic int getAccessibleSelectionCount()Returns the number of items currently selected. If no items are selected, the return value will be 0.- Specified by:
- getAccessibleSelectionCountin interface- AccessibleSelection
- Returns:
- the number of items currently selected.
 
- 
getAccessibleSelectionReturns an Accessible representing the specified selected item in the object. If there isn't a selection, or there are fewer items selected than the integer passed in, the return value will benull.- Specified by:

- i- the zero-based index of selected items
- Returns:
- an Accessible containing the selected item
- See Also:
 
- 
isAccessibleChildSelectedpublic boolean isAccessibleChildSelected(int i) Returns true if the current child of this object is selected.- Specified by:
- isAccessibleChildSelectedin interface- AccessibleSelection
- Parameters:
- i- the zero-based index of the child in this Accessible object.
- Returns:
- trueif the current child of this object is selected; else- false
- See Also:
 
- 
addAccessibleSelectionpublic 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:
- addAccessibleSelectionin interface- AccessibleSelection
- Parameters:
- i- the zero-based index of selectable items
- See Also:
 
- 
removeAccessibleSelectionpublic void removeAccessibleSelection(int i) 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:
- removeAccessibleSelectionin interface- AccessibleSelection
- Parameters:
- i- the zero-based index of selectable items
- See Also:
 
- 
clearAccessibleSelectionpublic void clearAccessibleSelection()Clears the selection in the object, so that nothing in the object is selected.- Specified by:
- clearAccessibleSelectionin interface- AccessibleSelection
 
- 
selectAllAccessibleSelectionpublic void selectAllAccessibleSelection()Causes every selected item in the object to be selected if the object supports multiple selections.- Specified by:
- selectAllAccessibleSelectionin interface- AccessibleSelection
