      protected RolloverRenderer getRolloverRenderer(Point location, boolean prepare)
      Description copied from class: RolloverController

    • getFocusedCell

      protected Point getFocusedCell()
      Description copied from class: RolloverController
      The coordinates of the focused cell in view coordinates. This method is called if the click action is invoked by a keyStroke. The returned cell coordinates should be related to what is typically interpreted as "focused" in the context of the component. p.x == focused column, p.y == focused row. A null return value or any coordinate value of invalid input: '<' 0 is interpreted as "outside".
      Specified by:
      getFocusedCell in class RolloverController<T extends JList>
      Returns:
      the location of the focused cell.
