Class DrawController

java.lang.Object

uk.ac.starlink.diva.DrawController

public class DrawController
extends Object

A basic controller implementation. This controller creates a useful and common interaction that can be used in simple applications. A single interactor 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.
