GraphStream編輯節點屬性並在GUI中顯示它們

Question

我在解析文件並創建具有屬性的節點后使用GraphStream導入文件。 創建節點后，我想要在GUI中編輯其屬性。 就像我在圖表的右側和左側在文本框中顯示我單擊的節點的屬性一樣。 比保存這些屬性。

我的代碼：

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：

公共類NodeClickListener實現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());
  }
  }

我想將屬性發送到表單，並在表單中為每個單擊的節點動態創建標簽和文本框，以便能夠編輯屬性。 有人對我該怎么做有任何想法嗎？ 也可能是線程之間的同步問題？

謝謝

僅使用從buttonPressed（）處理程序調用的JOptionPane對話框，這似乎對我有用。

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();
    }
}

應該看起來像這樣：
