JGraphX中的无向图

我尝试在JGraphx中显示图形。 只要我使用有向图形，一切都很好，但是当我试图显示一个无向的图形时，它会显示方向。

代码来自jgrapht的演示。

package org.jgrapht.demo; import com.mxgraph.layout.*; import com.mxgraph.swing.*; import java.awt.*; import java.nio.file.FileSystem; import javax.swing.*; import org.jgrapht.*; import org.jgrapht.ext.*; import org.jgrapht.graph.*; /** * A demo applet that shows how to use JGraphX to visualize JGraphT graphs. * Applet based on JGraphAdapterDemo. * * @since July 9, 2013 */ public class JGraphXAdapterDemo extends JApplet { private static final long serialVersionUID = 2202072534703043194L; private static final Dimension DEFAULT_SIZE = new Dimension(530, 320); private JGraphXAdapter jgxAdapter; /** * An alternative starting point for this demo, to also allow running this * applet as an application. * * @param args ignored. */ public static void main(String [] args) { JGraphAdapterDemo applet = new JGraphAdapterDemo(); applet.init(); JFrame frame = new JFrame(); frame.getContentPane().add(applet); frame.setTitle("JGraphT Adapter to JGraph Demo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.pack(); frame.setVisible(true); } /** * {@inheritDoc} */ public void init() { // create a JGraphT graph ListenableUndirectedGraph g = new ListenableUndirectedGraph( DefaultEdge.class); // create a visualization using JGraph, via an adapter jgxAdapter = new JGraphXAdapter(g); getContentPane().add(new mxGraphComponent(jgxAdapter)); resize(DEFAULT_SIZE); String v1 = "v1"; String v2 = "v2"; String v3 = "v3"; String v4 = "v4"; // add some sample data (graph manipulated via JGraphX) g.addVertex(v1); g.addVertex(v2); g.addVertex(v3); g.addVertex(v4); g.addEdge(v1, v2); g.addEdge(v2, v3); g.addEdge(v3, v1); g.addEdge(v4, v3); // positioning via jgraphx layouts mxCircleLayout layout = new mxCircleLayout(jgxAdapter); layout.execute(jgxAdapter.getDefaultParent()); // that's all there is to it!... } }

有可能表明它是无向的吗？

谢谢

Answer 1

您可以将mxGraphComponent边的样式设置为NONE ：

 mxGraphComponent graphComponent = new mxGraphComponent(jgxAdapter); mxGraphModel graphModel = (mxGraphModel)graphComponent.getGraph().getModel(); Collection
