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.

Method Details
-
propertyChange
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:
propertyChangein interfacePropertyChangeListener- Parameters:
e- PropertyChangeEvent
-
valueChanged
List Selection Listener value change method. Used to fire the property change- Specified by:
valueChangedin interfaceListSelectionListener- Parameters:
e- ListSelectionEvent
-
intervalAdded
List Data Listener interval added method. Used to fire the visible data property change- Specified by:
intervalAddedin interfaceListDataListener- Parameters:
e- ListDataEvent
-
intervalRemoved
List Data Listener interval removed method. Used to fire the visible data property change- Specified by:
intervalRemovedin interfaceListDataListener- Parameters:
e- ListDataEvent
-
contentsChanged
List Data Listener contents changed method. Used to fire the visible data property change- Specified by:
contentsChangedin interfaceListDataListener- Parameters:
e- ListDataEvent
-
getAccessibleStateSet
Get the state set of this object.- Overrides:
getAccessibleStateSetin classJComponent.AccessibleJComponent- Returns:
- an instance of AccessibleState containing the current state of the object
- See Also:
-
getAccessibleRole
Get the role of this object.- Overrides:
getAccessibleRolein classJComponent.AccessibleJComponent- Returns:
- an instance of AccessibleRole describing the role of the object
- See Also:
-
getAccessibleAt
Returns theAccessiblechild contained at the local coordinatePoint, if one exists. Otherwise returnsnull.- Specified by:
getAccessibleAtin interfaceAccessibleComponent- Overrides:
getAccessibleAtin classContainer.AccessibleAWTContainer- Parameters:
p- the point defining the top-left corner of theAccessible, given in the coordinate space of the object's parent- Returns:
- the
Accessibleat 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:
getAccessibleChildrenCountin classJComponent.AccessibleJComponent- Returns:
- the number of accessible children in the object.
-
getAccessibleChild
Return the nth Accessible child of the object.- Overrides:
getAccessibleChildin classJComponent.AccessibleJComponent- Parameters:
i- zero-based index of child- Returns:
- the nth Accessible child of the object
- See Also:
-
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:
getAccessibleSelectionin classAccessibleContext- Returns:
- this object
- See Also:
-
getAccessibleSelectionCount
public int getAccessibleSelectionCount()Returns the number of items currently selected. If no items are selected, the return value will be 0.- Specified by:
getAccessibleSelectionCountin interfaceAccessibleSelection- Returns:
- the number of items currently selected.
-
getAccessibleSelection
Returns 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:
getAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selected items- Returns:
- an Accessible containing the selected item
- See Also:
-
isAccessibleChildSelected
public boolean isAccessibleChildSelected(int i) Returns true if the current child of this object is selected.- Specified by:
isAccessibleChildSelectedin interfaceAccessibleSelection- Parameters:
i- the zero-based index of the child in this Accessible object.- Returns:
trueif the current child of this object is selected; elsefalse- See Also:
-
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:
addAccessibleSelectionin interfaceAccessibleSelection- Parameters:
i- the zero-based index of selectable items- See Also:
-
removeAccessibleSelection
public 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 interfaceAccessibleSelection- Parameters:
i- the zero-based index of selectable items- See Also:
-
clearAccessibleSelection
public void clearAccessibleSelection()Clears the selection in the object, so that nothing in the object is selected.- Specified by:
clearAccessibleSelectionin interfaceAccessibleSelection
-
selectAllAccessibleSelection
public void selectAllAccessibleSelection()Causes every selected item in the object to be selected if the object supports multiple selections.- Specified by:
selectAllAccessibleSelectionin interfaceAccessibleSelection
