getAccessibleChildrenCount
public int getAccessibleChildrenCount(JComponent c)
- Returns the number of accessible children in the object. If all
of the children of this object implement Accessible, than this
method should return the number of children of this object.
UI's might wish to override this if they present areas on the
screen that can be viewed as components, but actual components
are not used for presenting those areas.
Note: as of the Java 2 platform v1.3, it is recommended that developers call
Component.AccessibleAWTComponent.getAccessibleChildrenCount() instead
of using this method.
- Returns:
- the number of accessible children in the object.
- See Also:
getAccessibleChild(javax.swing.JComponent, int)
getAccessibleChild
public Accessible getAccessibleChild(JComponent c,
int i)
- Return the nth Accessible child of the object.
