Examples of diva.graph.GraphController

diva.graph.GraphController
A class that represents the main component of a typical graph editor. It is associated with a GraphPane, and manages interactors, renderers, and other parameters of user interaction (e.g. connector targets) to implement a flexible graph editor.
The interaction and rendering of nodes is managed by node controller objects, each associated with particular kind of node. Edges are similarly managed by an edge controller object. @author John Reekie @author Michael Shilman @author Steve Neuendorffer @version $Id: GraphController.java,v 1.15 2005/07/08 19:55:01 cxh Exp $ @Pt.AcceptedRating Red
