Question

我使用GraphStream在解析文件并创建带属性的节点后导入文件。创建节点后我想要的是在GUI中编辑他们的属性。就像我在右侧的Graph和左侧一样，在文本框中显示我点击的节点的属性。比保存这些属性。

我的代码：

frame = new JFrame();
        frame.setBounds(100, 100, 450, 300);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);



        LayersGraph lg=new LayersGraph();
        Viewer viewer=new Viewer ( lg.graph, Viewer.ThreadingModel.GRAPH_IN_ANOTHER_THREAD);

        viewer.enableAutoLayout();
        ViewerPipe fromViewer=viewer.newViewerPipe();

        lg.createGraph();



          View view=viewer.addDefaultView(false);


        clisten=new NodeClickListener(fromViewer,view,lg.graph);
        fromViewer.addViewerListener((ViewerListener) clisten);


        frame.getContentPane().add((Component) view);

        JTextArea textArea = new JTextArea();
        frame.getContentPane().add(textArea, BorderLayout.WEST);
        textArea.setText("The graph has etc....");

NodeClickListener：

公共类NodeClickListener实现ViewerListener，MouseInputListener {

public boolean loop = true; 
 private ViewerPipe vpipe = null; 
 private View vw = null; 
 private Graph graph = null; 

 public HashMap<String,String> attributes=new HashMap<String,String>();


 /**
  * Constructor 
  * @param vpipe - Viewer Pipe of the graph UI 
  * @param vw - View of the current graph in swing 
  * @param g - graph object for the current graph in use 
  */ 
 public NodeClickListener(ViewerPipe vpipe, View vw, Graph g) { 
  this.loop=true; 
  this.vpipe = vpipe; 
  this.vw = vw; 
  this.graph = g; 
  // Keep piping back while grph is out to hook mouse clicks 
  this.vw.addMouseListener(this); 

 } 


 /**
  * Close the view when graph is no longer needed and detach all listners 
  * @param id - not used, but inherited by interface 
  */ 
 public void viewClosed(String id) { 
  loop = false; 
  vw.removeMouseListener(this); 


 } 
 /**
  * Button push hook to label nodes/edges 
  * @param id - string id of node 
  */ 
 public void buttonPushed(String id) { 
  System.out.println("Button pushed on node "+id); 
  Node n = graph.getNode(id); 
  //String _ui_label = n.getAttribute("_ui.label"); 
  String ui_label = n.getAttribute("ui.label");  

  System.out.println("ui_label: "+ui_label);


  for(String key:n.getEachAttributeKey()){
      Object value=n.getAttribute(key);
      System.out.println("Key: "+key+" Value: "+value.toString());
      attributes.put(key, value.toString());
  }
  }

我想将属性发送到表单和表单，以便为单击的每个节点动态创建标签和文本框，以便能够编辑属性。任何人都知道我该怎么做？它也可能是线程之间同步的问题？

这似乎对我来说只使用从buttonPressed（）处理程序调用的JOptionPane对话框。

public static void main(String args[]) throws IOException {

    final DefaultGraph g = new DefaultGraph("my beautiful graph");
    g.setStrict(false);
    Viewer viewer = new Viewer(g, Viewer.ThreadingModel.GRAPH_IN_GUI_THREAD);
    JFrame myJFrame = new JFrame();
    myJFrame.setPreferredSize(new Dimension(600, 600));
    DefaultView view = (DefaultView) viewer.addDefaultView(false);   // false indicates "no JFrame".
    view.setPreferredSize(new Dimension(400, 400));
    myJFrame.setLayout(new FlowLayout());
    myJFrame.add(view);
    JButton myButton = new JButton("MyButton");
    myButton.addActionListener(e -> System.out.println("Somebody pushed my button."));
    myJFrame.add(myButton);
    JSlider slider = new JSlider();
    slider.addChangeListener(e -> view.getCamera().setViewPercent(slider.getValue() / 10.0));
    myJFrame.add(slider);
    myJFrame.pack();
    myJFrame.setVisible(true);
    myJFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    viewer.enableAutoLayout();
    ViewerPipe vp = viewer.newViewerPipe();
    vp.addViewerListener(new ViewerListener() {
        @Override
        public void viewClosed(String viewName) {
            // dont care
        }

        @Override
        public void buttonPushed(String id) {
            Node n = g.getNode(id);
            String attributes[] = n.getAttributeKeySet().toArray(new String[n.getAttributeKeySet().size()]);

            String attributeToChange = (String) JOptionPane.showInputDialog(null, "Select attibute to modify", "Attribute for " + id, JOptionPane.QUESTION_MESSAGE, null, attributes, attributes[0]);
            String curValue = n.getAttribute(attributeToChange);
            String newValue
                    = JOptionPane.showInputDialog("New Value", curValue);
            n.setAttribute(attributeToChange, newValue);
        }

        @Override
        public void buttonReleased(String id) {
            // don't care
        }
    });
    g.addNode("A");
    g.addNode("B");
    g.addNode("C");

    g.addNode("E");
    g.addNode("F");
    g.addNode("G");

    g.addNode("1");
    g.addNode("2");
    g.addNode("3");

    g.addNode("4");
    g.addNode("5");
    g.addNode("6");

    g.addEdge("AB", "A", "B");
    g.addEdge("AC", "B", "C");
    g.addEdge("BC", "C", "C");

    g.addEdge("EB", "E", "B");
    g.addEdge("FC", "F", "C");
    g.addEdge("GC", "G", "C");

    g.addEdge("1B", "1", "B");
    g.addEdge("2C", "2", "C");
    g.addEdge("3C", "3", "C");

    g.addEdge("4B", "4", "B");
    g.addEdge("5C", "5", "C");
    g.addEdge("6C", "6", "C");

    g.getNode("A").setAttribute("size", "big");
    g.getNode("B").setAttribute("size", "medium");
    g.getNode("C").setAttribute("size", "small");
    g.getNode("A").setAttribute("ui:color", "red");
    g.getNode("B").setAttribute("ui:color", "blue");
    g.getNode("C").setAttribute("ui:color", "green");

    for (Node node : g) {
        node.addAttribute("ui.label", node.getId());
    }
    while (true) {
        (view).repaint();
        vp.pump();
    }
}
