prefuse.controls.FocusControl
public class FocusControl
Updates the contents of a TupleSet of focus items in response to mouse actions. For example, clicking a node or double-clicking a node could update its focus status. This Control supports monitoring a specified number of clicks to executing a focus change. By default a click pattern will cause a VisualItem to become the sole member of the focus group. Hold down the control key while clicking to add an item to a group without removing the current members.
Updating a focus group does not necessarily cause the display to change. For this functionality, either register an action with this control, or register a TupleSetListener with the focus group.
