    - #### 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`
      Parameters:
        `listener` - the PropertyChangeListener to be added
      See Also:
        `AccessibleContext.ACCESSIBLE_NAME_PROPERTY`, `AccessibleContext.ACCESSIBLE_DESCRIPTION_PROPERTY`, `AccessibleContext.ACCESSIBLE_STATE_PROPERTY`, `AccessibleContext.ACCESSIBLE_VALUE_PROPERTY`, `AccessibleContext.ACCESSIBLE_SELECTION_PROPERTY`, `AccessibleContext.ACCESSIBLE_TEXT_PROPERTY`, `AccessibleContext.ACCESSIBLE_VISIBLE_DATA_PROPERTY`

    - #### removePropertyChangeListener

          public void removePropertyChangeListener(PropertyChangeListener listener)

      Remove a PropertyChangeListener from the listener list. This removes a PropertyChangeListener that was registered for all properties.
