org.graphstream.ui.view.ViewerPipe

Shell around a proxy pipe coming from the viewer allowing to put viewer listeners on a viewer that runs in a distinct thread.

This pipe is a probe that you can place in the event loop between the viewer and the graph. It will transmit all events coming from the viewer to the graph (or any sink you connect to it). But in addition it will monitor standard attribute changes to redistribute them to specify "viewer listeners".

As any proxy pipe, a viewer pipe must be "pumped" to receive events coming from other threads.


  protected boolean loop = true;


  public DemoViewerColorInterpolation() {
    Graph graph = new MultiGraph("main graph");
    ViewerPipe pipe = graph.display(false).newViewerPipe();


    // graph.addAttribute( "ui.quality" );
    graph.addAttribute("ui.antialias");


    pipe.addViewerListener(this);


    Node A = graph.addNode("A");
    Node B = graph.addNode("B");
    Node C = graph.addNode("C");


    graph.addEdge("AB", "A", "B", true);
    graph.addEdge("BC", "B", "C", true);
    graph.addEdge("CA", "C", "A", true);


    A.addAttribute("xyz", 0, 1, 0);
    B.addAttribute("xyz", 1, 0, 0);
    C.addAttribute("xyz", -1, 0, 0);


    graph.addAttribute("ui.stylesheet", styleSheet);


    float color = 0;
    float dir = 0.01f;


    while (loop) {
      try {
        Thread.sleep(100);
      } catch (InterruptedException e) {
        e.printStackTrace();
      }


      pipe.pump();


      color += dir;
