java.lang.Object
  com.rubecula.darwin.visualization.FlipFlopButtons

All Implemented Interfaces:

ActionListener, EventListener

public class FlipFlopButtons
extends Object
implements ActionListener

Class which manages a set of JButtons (usually of cardinality two), belonging to a container and, when pressed, invoking calls to an implementer of ControlAction. When a button is pressed, two things will happen:

1. the ControlAction implementer will be called with ControlAction.setState(String) where the parameter is the action command for the button;
2. every button's enabled state will be flipped.
