i - zero-based index of child objects

clearAccessibleSelection

public void clearAccessibleSelection()
Unselect all children of this Accessible object.
Specified by:
clearAccessibleSelection in interface AccessibleSelection

getAccessibleChild

public Accessible getAccessibleChild(int i)
Returns the ith accessible child. Subclasses must override this if they can have children.
Overrides:
getAccessibleChild in interface Component.AccessibleAWTComponent
Returns:
the ith accessible child, or null

getAccessibleChildrenCount

public int getAccessibleChildrenCount()
Returns the number of children of this component which implement Accessible. Subclasses must override this if they can have children.

getAccessibleChildrenCount in interface Component.AccessibleAWTComponent
Returns:
the number of accessible children, default 0

getAccessibleRole

public AccessibleRole getAccessibleRole()
Returns the role of this component.
Overrides:
getAccessibleRole in interface Component.AccessibleAWTComponent
Returns:
the accessible role

Overrides:
getAccessibleStateSet in interface Component.AccessibleAWTComponent
Returns:
a new state set

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.
Specified by:

Parameters:
i - zero-based index of child objects
Returns:
true if specified child exists and is selected

itemStateChanged

public void itemStateChanged(ItemEvent event)
This method is called when an item's state is changed.
Specified by:
itemStateChanged in interface ItemListener
Parameters:
event - the ItemEvent indicating the change
