修改此類渲染，將進度條的大小更改爲變量？

Question

我有這樣的代碼：

TableColumn column = jTable2.getColumnModel().getColumn(1); 
column.setCellRenderer(new ProgressRenderer()); 

類ProgressRenderer：

class ProgressRenderer extends DefaultTableCellRenderer { 
    private final JProgressBar b = new JProgressBar(0, 100);// I NEED RECEIVE DE VALUE,    //LIKE THIS new JProgressBar(0, MAX); 
    private final JPanel p = new JPanel(new BorderLayout()); 

    public ProgressRenderer() { 
     super(); 
     setOpaque(true); 
    b.setStringPainted(true); 
     p.add(b); 
     //p.setBorder(BorderFactory.createEmptyBorder(1, 1, 1, 1)); 
    } 
    @Override 
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { 
     Integer i = (Integer) value; 

     String text = "Finalizou o Lote"; 
     if (i < 0) { 
      text = "Pausa"; 
     } else if (i < 100) { 
      b.setValue(i); 
      return p; 
     } 
     super.getTableCellRendererComponent(table, text, isSelected, hasFocus, row, column); 
     return this; 
    } 

    @Override 
    public void updateUI() { 
     super.updateUI(); 
     if (p != null) { 
      SwingUtilities.updateComponentTreeUI(p); 
     } 
    } 
} 

現在，我需要，當ProgressRenderer通話功能（）difine一個參數，它是最大的進度條，但我可以不做，有什麼想法？

像這樣：

TableColumn column = jTable2.getColumnModel().getColumn(1); 
    column.setCellRenderer(new ProgressRenderer(MAX)); 

類ProgressRenderer（）

class ProgressRenderer extends DefaultTableCellRenderer { 
    private final JProgressBar b = new JProgressBar(0, MAX);// I NEED RECEIVE DE VALUE,    //LIKE THIS new JProgressBar(0, MAX); 
    private final JPanel p = new JPanel(new BorderLayout()); 

    public ProgressRenderer() { 
     super(); 
     setOpaque(true); 
... 
... 

----編輯---------- 謝謝你，但現在我有大問題，因爲這個：

TableColumn column = jTable2.getColumnModel() GetColumn (1).; 
    column.setCellRenderer (new ProgressRenderer (maxValue));// 

//我怎麼知道什麼時候加t他反對改變包括maxValue

我在JTable中

private LinhasOnline getLinha() { 

    LinhasOnline linha = new LinhasOnline(); 
    linha.setNome("Linha "+j); 
      linha.setcont(j*(10)); 
      linha.setmax(100); 

      j++; 
      return linha; 
} 

private void addLinha() { 
    getModel().addLinha(getLinha());// 
} 

//我getmodel

private LinhasOnlineTableModel getModel() { 
    if (model == null) { 
     model = (LinhasOnlineTableModel) getTblLinhasOnline().getModel(); 
    } 
    return model; 
} 

//我getTblLinhasOnline使用插入值這個代碼（）

private JTable getTblLinhasOnline() { 
    if (jTable2 == null) { 
     jTable2 = new JTable(); 
     jTable2.setModel(new LinhasOnlineTableModel()); 
        TableColumn column = jTable2.getColumnModel().getColumn(1); 
        column.setCellRenderer(new ProgressRenderer(max)); // need put the value of object(setmax) 
    } 
    return jTable2; 
}

你可以像下一樣改變你的班級：

class ProgressRenderer extends DefaultTableCellRenderer { 
    private final JProgressBar b;// I NEED RECEIVE DE VALUE,    //LIKE THIS new JProgressBar(0, MAX); 
    private final JPanel p = new JPanel(new BorderLayout()); 

    public ProgressRenderer(int maxValue) { 
     super(); 
     b = new JProgressBar(0, maxValue); 
     setOpaque(true); 
     b.setStringPainted(true); 
     p.add(b); 
    } 
    ... 
}
