getAccessibleChildrenCount

public int getAccessibleChildrenCount()

Returns the number of accessible children in the object. If all of the children of this object implement Accessible, then this method should return the number of children of this object.

Overrides:: getAccessibleChildrenCount in class Component.AccessibleAWTComponent
Returns:: the number of accessible children in the object

getAccessibleChild

public Accessible getAccessibleChild(int i)

Returns the nth Accessible child of the object.

Overrides:: getAccessibleChild in class Component.AccessibleAWTComponent
Parameters:: i - zero-based index of child
Returns:: the nth Accessible child of the object
See Also:: AccessibleContext.getAccessibleChildrenCount()

getAccessibleAt

public Accessible getAccessibleAt(Point p)

Returns the Accessible child, if one exists, contained at the local coordinate Point.

Specified by:: getAccessibleAt in interface AccessibleComponent
Overrides:: getAccessibleAt in class Component.AccessibleAWTComponent
Parameters:: p - the point defining the top-left corner of the Accessible, given in the coordinate space of the object's parent
Returns:: the Accessible, if it exists, at the specified location; else null

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a PropertyChangeListener to the listener list.

Overrides:: addPropertyChangeListener in class Component.AccessibleAWTComponent
