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()

getAccessibleAt

public Accessible getAccessibleAt(Point p)

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

Overrides:

getAccessibleAt in class JComponent.AccessibleJComponent

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.

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 if one exists. Otherwise return null.

Overrides:

getAccessibleSelection in class AccessibleContext

Tags copied from class: AccessibleContext

Returns:

AccessibleSelection if supported by object; else return null

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.
