isAccessibleChildSelected

public boolean isAccessibleChildSelected(int n)
Returns true if the n-th child is selected, false otherwise.

Specified by:
isAccessibleChildSelected in interface AccessibleSelection
Parameters:
n - the index of the child of which the selected state is queried
Returns:
true if the n-th child is selected, false otherwise

addAccessibleSelection

public void addAccessibleSelection(int i)
Adds the accessible item with the specified index to the selected items. If multiple selections are supported, the item is added to the selection, otherwise the item replaces the current selection.

Specified by:
addAccessibleSelection in interface AccessibleSelection
Parameters:
i - the index of the item to add to the selection

removeAccessibleSelection

public void removeAccessibleSelection(int i)
Removes the accessible item with the specified index to the selection.

Specified by:
removeAccessibleSelection in interface AccessibleSelection
Parameters:
i - the index of the item to be removed from the selection

clearAccessibleSelection

public void clearAccessibleSelection()
Remove all selection items from the selection.

Specified by:
clearAccessibleSelection in interface AccessibleSelection

selectAllAccessibleSelection

public void selectAllAccessibleSelection()
Selects all items if multiple selections are supported. Otherwise do nothing.

Specified by:
selectAllAccessibleSelection in interface AccessibleSelection

valueChanged

public void valueChanged(ListSelectionEvent event)
Receices notification when the list selection is changed. This method fires two property change events, the first with AccessibleContext.ACCESSIBLE_VISIBLE_DATA_PROPERTY and the second with AccessibleContext.ACCESSIBLE_SELECTION_PROPERTY.

Specified by:
valueChanged in interface ListSelectionListener
Parameters:
event - the list selection event

contentsChanged

public void contentsChanged(ListDataEvent event)
Receives notification when items have changed in the JList. This method fires a property change event with AccessibleContext.ACCESSIBLE_VISIBLE_DATA_PROPERTY.

Specified by:
contentsChanged in interface ListDataListener
Parameters:
event - the list data event

intervalAdded

public void intervalAdded(ListDataEvent event)
Receives notification when items are inserted into the JList. This method fires a property change event with AccessibleContext.ACCESSIBLE_VISIBLE_DATA_PROPERTY.

Specified by:
intervalAdded in interface ListDataListener

Specified by:
intervalRemoved in interface ListDataListener
Parameters:
event - the list data event

propertyChange

public void propertyChange(PropertyChangeEvent e)

Specified by:
getAccessibleAt in interface AccessibleComponent
Overrides:
getAccessibleAt in class Container.AccessibleAWTContainer
Parameters:
p - the screen location for which to return the accessible child
Returns:
the accessible child at the specified location, or null if there is no child at that location

getAccessibleChildrenCount
