public abstract class BaseAction

extends Object

implements JCAction, Serializable

BaseAction is an abstract base class for the Java3D actions of JCChart 3D. It implements the JCAction interface used for JCChart 3D actions. It defines methods for starting, animating, ending and cancelling an action. JCChart3dArea will create an instance of the appropriate JCAction when an action is started, and will call start(), animate() and end() during mouseDown(), mouseDrag() and mouseUp() respectively. The appropriate JCAction is dependent on the event. A mapping from event to action type is stored the chart's JCActionTable

Constructor Detail

BaseAction

public BaseAction()

Constructs a BaseAction. Note that it nees to be connected to a JCChart3dArea instance so this needs to be set later.
