public void addAccessibleSelection(int i)
Accessible
child of the object

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.

If there is no Accessible
child, null
is returned.

generally isn't a localized name, and doesn't have meaning for the
user. If the object is fundamentally a text object (e.g. a menu item), the
accessible name should be the text of the object (e.g. "save").
If the object has a tooltip, the tooltip text may also be an
appropriate String to return.

If the parent of this object implements Accessible

this method should simply return getParent

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.
