- the number of accessible children in the object
-
getAccessibleChild
public Accessible getAccessibleChild(int i)
Returns the nthAccessiblechild of the object.- Overrides:
getAccessibleChildin classComponent.AccessibleAWTComponent- Parameters:
i- zero-based index of child- Returns:
- the nth
Accessiblechild of the object - See Also:
AccessibleContext.getAccessibleChildrenCount()
-
getAccessibleAt
public Accessible getAccessibleAt(Point p)
Returns theAccessiblechild, if one exists, contained at the local coordinatePoint.- Specified by:
getAccessibleAtin interfaceAccessibleComponent- Overrides:
getAccessibleAtin classComponent.AccessibleAWTComponent- Parameters:
p- the point defining the top-left corner of theAccessible, given in the coordinate space of the object's parent- Returns:
- the
Accessible, if it exists, at the specified location; elsenull
-
addPropertyChangeListener
public void addPropertyChangeListener(PropertyChangeListener listener)
