The result may be null if there is none or if rollover is not enabled. If the prepare flag is true, the renderer will be prepared with value and state as appropriate for the given location. Note: PRE - the location must be valid in cell coordinate space.

Specified by:

getRolloverRenderer in class RolloverController<T extends JTree>

Parameters:

location - a valid location in cell coordinates, p.x == column, p.y == row.

RolloverRenderer at the given location

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 < 0 is interpreted as "outside".

Specified by:

getFocusedCell in class RolloverController<T extends JTree>

Returns:

the location of the focused cell.
