org.graphstream.ui.swingViewer.GraphRenderer

Interface for classes that draw a GraphicGraph in a swing component.

There are two rendering mechanisms in the Swing ui package : the viewer and the renderers. The viewer is a complete architecture to render a graph in a panel or frame, handling all the details. The renderer architecture is a way to only render the graph in any surface, handled directly by the developer. When using the render you are must handle the graphic graph by yourself, but you have a lot more flexibility.

The viewer mechanisms uses graph renderers.

  public void setRenderer(RendererType rendererType) {
    try {
      Class<? extends GraphRenderer> clazz = (Class<? extends GraphRenderer>) Class
          .forName(rendererType.classname);


      GraphRenderer obj = clazz.newInstance();


      if (this.renderer != null)
        this.renderer.close();


      this.renderer = obj;

  }


  public Viewer display(boolean autoLayout) {
    Viewer viewer = new Viewer(this,
        Viewer.ThreadingModel.GRAPH_IN_ANOTHER_THREAD);
    GraphRenderer renderer = Viewer.newGraphRenderer();
    viewer.addView(Viewer.DEFAULT_VIEW_ID, renderer);
    if (autoLayout) {
      Layout layout = Layouts.newLayoutAlgorithm();
      viewer.enableAutoLayout(layout);
    }
