Interface java.awt.accessibility.AccessibleSelection
- Implementing Classes:
- JTabbedPane.AccessibleJTabbedPane, JList.AccessibleJList, JTree.AccessibleJTree, JTree.AccessibleJTree.AccessibleJTreeNode, JMenuBar.AccessibleJMenuBar
- public interface AccessibleSelection
This AccessibleSelection interface
provides the standard mechanism for an assistive technology to determine
what the current selected children are, as well as modify the selection set.
Any object that has children that can be selected should support this
the AccessibleSelection interface. Applications can determine if an object supports the
AccessibleSelection interface by first obtaining its AccessibleContext (see
Accessible) and
then calling the
getAccessibleSelection method of AccessibleContext. If the return
value is not null, the object supports this interface.

- Accessible, getAccessibleContext, AccessibleContext, getAccessibleSelection
getAccessibleSelectionCount
public int getAccessibleSelectionCount()
- Returns the number of Accessible children currently selected.
If no children are selected, the return value will be 0.
- Returns:
- the number of items currently selected.
getAccessibleSelection
public Accessible getAccessibleSelection(int i)
- Returns an Accessible representing the specified selected child
in the object. If there isn't a selection, or there are
fewer children selected than the integer passed in, the return
value will be null.
Note that the index represents the i-th selected child, which
is different from the i-th child.
- Parameters:
i
- the zero-based index of selected children
- Returns:
- the i-th selected child
- See Also:
- getAccessibleSelectionCount
isAccessibleChildSelected
public boolean isAccessibleChildSelected(int i)
- Determines if the current child of this object is selected.
- Parameters:
i
- the zero-based index of the child in this Accessible object.
- Returns:
- true if the current child of this object is selected; else false.
- See Also:
- getAccessibleChild
addAccessibleSelection
public void addAccessibleSelection(int i)
- Adds the specified Accessible child of the object to the object's
selection. If the object supports multiple selections,
the specified child is added to any existing selection, otherwise
it replaces any existing selection in the object. If the
specified child is already selected, this method has no effect.
- Parameters:
i
- the zero-based index of the child
- See Also:
- getAccessibleChild
removeAccessibleSelection
public void removeAccessibleSelection(int i)
- Removes the specified child of the object from the object's
selection. If the specified item isn't currently selected, this
method has no effect.
- Parameters:
i
- the zero-based index of the child
- See Also:
- getAccessibleChild
clearAccessibleSelection
public void clearAccessibleSelection()
- Clears the selection in the object, so that no children in the
object are selected.
selectAllAccessibleSelection
public void selectAllAccessibleSelection()
- Causes every child of the object to be selected
if the object supports multiple selections.
