Interface InteractionSource


public interface InteractionSource

Title: InteractionSource

Description: This is the interface for an object that the user can interact with. The object contains one or several interaction targets, which are hot spots that respond to user interaction by issuing an interaction event.

Classes implementing this class should document what targets they contain.

Classes implementing the InteractionListener interface can register to receive interaction events using the addInteractionListener method of this interface.
