Class BasicController

java.lang.Object
  diva.canvas.toolbox.BasicController

public class BasicController
extends java.lang.Object

A basic controller implementation. This controller creates a useful and common interaction that can be used in simple applications. A single interactor, accessed through getRole(), provides selection and dragging. Clients that wish to use this default interaction can give this interactor to figures that they add to the foreground layer of the corresponding pane.
