Examples of diva.canvas.Figure

diva.canvas.Figure
A Figure is a persistent object drawn on the screen. This interface roots a small tree of interfaces that define various roles that different kinds of figures play. It is also implemented by the AbstractFigure class, which roots the tree of concrete figure classes. @version $Id: Figure.java,v 1.11 2005/07/08 19:54:45 cxh Exp $ @author John Reekie @Pt.AcceptedRating Yellow
