Re: Request about Graphstream project

[Antoine Dutot <antoine.dutot AT gmail.com>]

Hello Bastien,

There are two viewers in GraphStream, the basic one does not allows edge shapes other than lines. You have to download the advanced viewer (gs-ui module on the download page), put it in the class path, and enable it globally like this is described here.

Hope this helps,

Best regards,

Hello,

I send you this mail to enquire some information about using style to customize "Graph", "Nodes" and "Edges".

In fact, we create a stylesheet and basically apply this by the method "addAttribute()". Unfortunately, all the specifications of the style are applied except for the shape property for the edges.

Please, find the following code :

===================================== CODE ==============================================

import javax.swing.JFrame;
import org.graphstream.ui.graphicGraph.GraphicGraph;
import org.graphstream.ui.swingViewer.Viewer;

        String stylesheet = "graph { fill-color: white;}"
        stylesheet += "node { shape: box; size: 20px; fill-color: red;}";
        stylesheet += "edge { fill-color: blue; shape: cubic-curve;}";
       
        GraphicGraph graph = new GraphicGraph("GraphicGraph");

        Viewer viewer = new Viewer(graph, Viewer.ThreadingModel.GRAPH_IN_ANOTHER_THREAD);
        viewer.disableAutoLayout();
       
        graph.addAttribute("ui.quality");
        graph.addAttribute("ui.antialias");

        graph.addAttribute("ui.stylesheet", stylesheet);
       
        graph.addNode("A");
        graph.addNode("B");
        graph.addNode("C");
       
        graph.addEdge("AB", "A", "B", false);
        graph.addEdge("BC", "B", "C", true);
        graph.addEdge("CA", "C", "A", false);
       
        viewer.enableAutoLayout();
       
        JFrame frame = new JFrame("GraphicGraph");
        frame.setContentPane(viewer.addDefaultView(false));
        frame.pack();
        frame.setSize(800,800);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

================================== END OF CODE =========================================


The result is visible on the following screenshot :




As you can see, the shape style doesn't work with this method. I hope there is a mistake in the proposed code and you have a way to do that.

You will be most helpful,
