GraphStream圖不能正確渲染

Question

我試圖在窗體中顯示圖形時有以下代碼。 對於3個節點，代碼運行良好，但在添加其他節點之後，該圖不會完全顯示。我不知道問題出在哪裏。

public class Test{ 
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)); 
    SwingBasicGraphRenderer renderer = new SwingBasicGraphRenderer(); 
    DefaultView view = new DefaultView(viewer, "MyView", renderer); 
    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); 
    myJFrame.pack(); 
    myJFrame.setVisible(true); 
    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("color", "red"); 
    g.getNode("B").setAttribute("color", "blue"); 
    g.getNode("C").setAttribute("color", "green"); 
    while (true) { 
     (view).repaint(); 
     vp.pump(); 
    } 
} 
} 

圖表：

Answer 1

因爲它似乎不可預知移動，我可以現在做的最好的是要縮小這樣一切都會在視圖中。

view.getCamera().setViewPercent(5.0); 

更新：

它似乎更好地工作投viewrt.getDefaultView（）的默認視圖，而不是直接調用構造函數DefaultVeiw。

變化

SwingBasicGraphRenderer renderer = new SwingBasicGraphRenderer(); 
DefaultView view = new DefaultView(viewer, "MyView", renderer); 

到

DefaultView view = (DefaultView) viewer.addDefaultView(false);
