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 the AccessibleSelection
interface.
Applications can determine if an object supports the
AccessibleSelection
interface by first obtaining its
AccessibleContext
(see Accessible
) and then calling the
AccessibleContext.getAccessibleSelection()
method. If the return value
is not null
, the object supports this interface.- See Also:

Method Details
-
getAccessibleSelectionCount
int getAccessibleSelectionCount()Returns the number ofAccessible
children currently selected. If no children are selected, the return value will be 0.- Returns:
- the number of items currently selected
-
getAccessibleSelection
Returns anAccessible
representing the specified selected child of the object. If there isn't a selection, or there are fewer children selected than the integer passed in, the return value will benull
.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:
-
isAccessibleChildSelected
boolean isAccessibleChildSelected(int i) Determines if the current child of this object is selected.- Parameters:
i
- the zero-based index of the child in thisAccessible
object- Returns:
true
if the current child of this object is selected; elsefalse
- See Also:
-
addAccessibleSelection
void addAccessibleSelection(int i) Adds the specifiedAccessible
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:
-
removeAccessibleSelection
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:
-
clearAccessibleSelection
void clearAccessibleSelection()Clears the selection in the object, so that no children in the object are selected. -
selectAllAccessibleSelection
void selectAllAccessibleSelection()Causes every child of the object to be selected if the object supports multiple selections.
