All Implemented Interfaces:: ImageObserver, MenuContainer, Serializable, ScrollPaneConstants, AnimationListener, View, View2DConstants, ViewContainer

Direct Known Subclasses:: Overview

public class Graph2DView
extends JComponent
implements View, ViewContainer, ScrollPaneConstants, View2DConstants, AnimationListener
extends JComponent
implements View, ViewContainer, ScrollPaneConstants, View2DConstants, AnimationListener

This is a powerful component to view graphs in 2-dimensional space. It displays a Graph2D object. The same Graph2D object can be displayed at different zoom levels in different views.

Features of this component include

Zooming
Built in scrollbars
Different drawing modes, e.g. Grid mode
Built in text editor for node and edge labels
Printing capabilities
Drawing a graph in different levels of detail
Inlined label editor
So called view modes that define its interactive behaviour.

Constructor Summary
`Graph2DView()` Creates a new Graph2DView containing an empty graph.
`Graph2DView(Graph2D graph)` Creates a new Graph2DView for a given graph.
`Graph2DView(Graph2D graph, ViewControl vc)` Creates a new Graph2DView for a given graph and viewcontrol.

Method Summary
`void`	`addBackgroundDrawable(Drawable d)` Adds a background drawable to this view.
`void`	`addDrawable(Drawable d)` Adds a drawable to this view.
`void`	`addViewChangeListener(ViewChangeListener l)` View can not change, so this method does nothing.
