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
See Also:
Component.AccessibleAWTComponent.getAccessibleChildrenCount()

getAccessibleChildrenCount

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

Returns:
the number of accessible children, default 0

getAccessibleRole

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