- CheckboxMenuItem.AccessibleAWTCheckboxMenuItem, JComboBox.AccessibleJComboBox, JList.AccessibleJList, JMenu.AccessibleJMenu, JMenuBar.AccessibleJMenuBar, JTabbedPane.AccessibleJTabbedPane, JTable.AccessibleJTable, JTree.AccessibleJTree, JTree.AccessibleJTree.AccessibleJTreeNode, List.AccessibleAWTList, Menu.AccessibleAWTMenu, MenuBar.AccessibleAWTMenuBar, MenuComponent.AccessibleAWTMenuComponent, MenuItem.AccessibleAWTMenuItem, PopupMenu.AccessibleAWTPopupMenu
If an object implements this interface then it must be able to control
the selection of its children. Accessibility software can use the
implementations of this interface to change the selection set of children.
The
AccessibleContext.getAccessibleSelection() method should
return
null if an object does not implement this interface.
addAccessibleSelection
public void addAccessibleSelection(int i)
Select the specified child if it is not already selected, placing it in
the object's current selection. If the object does not support multiple
selections then the new selection replaces the old. If the specified
child is already selected, or is out of bounds, this method does nothing.
i - zero-based index of child objects
getAccessibleSelection
public Accessible getAccessibleSelection(int i)
Returns the i-th selected child (not necessarily the overall i-th child)
of this Accessible object. If i is out of bounds, null is returned.
i - zero-based index of selected child objects
- the Accessible child, or null
getAccessibleSelectionCount
public int getAccessibleSelectionCount()
Returns the number of currently selected Accessible children, which may
be 0 if nothing is selected.
- the number of selected children
isAccessibleChildSelected
public boolean isAccessibleChildSelected(int i)
Determine if i-th overall child of this accessible object is selected.
If i is out of bounds, false is returned.
i - zero-based index of child objects
- true if specified child exists and is selected
removeAccessibleSelection
public void removeAccessibleSelection(int i)
Unselect the specified child of this Accessible object. If the specified
child is not selected, or is out of bounds, this method does nothing.
i - the zero-based index of the child objects
selectAllAccessibleSelection
public void selectAllAccessibleSelection()
Select all children of this Accessible object if the object supports
multiple selections or has a single child. Otherwise this does nothing.
