JFrame在收到事件后不绘画

Question

我有我的代码在下面，我试图接收m_rows这是一个数组。它看起来像保持空白，我的框架保持空白。我可以看到班上收到了这个活动。我认为我的班级表工作正常。在接收到来自监听器的m_rows并将它传递给TableModel（m_rows）之间的代码中，你看到下面的代码有什么明显的错误吗？

感谢

class Frame extends JFrame implements FlowListener { 

    private List<Candle> m_rows = new ArrayList<Candle>(); 

    public Frame() { 

     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     setTitle("Ma premiere fenetre"); 
     setBounds(50, 100, 1000, 800); 

     Container conteneur = new JPanel(); 
     TableModel tableModel = new TableModel(m_rows); 
     JTable table = new JTable(tableModel); 

     JPanel tablePanel = new JPanel(); 

     tablePanel.add(table); 

     conteneur.setLayout(new GridLayout(2, 1)); 
     conteneur.add(tablePanel); 

     this.add(conteneur); 
     this.setVisible(true); 

    } 

    @Override 
    public void updateOnFlow(List<Candle> newFlow) { 
     m_rows = newFlow; 
     this.repaint(); 

    } 

}

我认为问题是，要m_row分配的东西对TableModel没有影响。试试这个：

class Frame extends JFrame implements FlowListener { 
    private JTable table; 
    ... 

    public Frame() { 
     ... 
     TableModel tableModel = new TableModel(m_rows); // Did you mean DefaultTableModel? 
     table = new JTable(tableModel); 
     ... 
    } 

    @Override 
    public void updateOnFlow(List<Candle> newFlow) { 
     m_rows = newFlow; 
     TableModel tableModel = new TableModel(m_rows); 
     table.setModel(tableModel); 
     this.repaint(); 
    } 
}
