The class used to obtain the accessible role for this object.
Warning: serialized objects of this class will not be compatible with
future swing releases. The current serialization support is appropriate
for short term storage or RMI between Swing1.0 applications. It will
not be possible to load serialized Swing1.0 objects with future releases
of Swing. The JDK1.2 release of Swing will be the compatibility
baseline for the serialized form of Swing objects.

getAccessibleAt
public Accessible getAccessibleAt(Point p)
- Returns the Accessible child, if one exists, contained at the local
coordinate Point.
- Parameters:
p
