具有相同自定義模型的兩個JXTables - 如何使單元格在一個表格中可編輯，但在第二個表格中不可編輯？

Question

我有一個自定義表模型，其數據要在一個JXTable中進行編輯，但僅在第二個JXTable中進行查看。這可以做到沒有兩個單獨的模型？ 是否有某種方式重寫for view-only表的model.isCellEditable？

public class SSCCE extends JPanel { 

    private JSplitPane splitPane; 
    private JXTable viewTable, editTable; 

    private class CustomModel extends AbstractTableModel { 

    public static final int SPORT_COL = 0; 
    public static final int EQUIPMENT_COL = 1; 
    private final String[] COLUMN_NAMES = { 
     "Sport", 
     "Equipment"

     } 
     }

    @Override

    public SSCCE() { 
    super(); 

    model = new CustomModel(); 
    viewTable = new JXTable(model); 
    editTable = new JXTable(model); 
    editTable.addHighlighter(new ColorHighlighter(new HighlightPredicate() {

     public boolean isHighlighted(Component renderer, ComponentAdapter adapter) { 
     return adapter.isEditable(); 
     } 
    }, Color.GREEN.brighter(), Color.BLACK)); 

    JPanel panelLeft = new JPanel(new BorderLayout(0, 10)); 
    panelLeft.add(new JLabel("Editable"), BorderLayout.NORTH); 
    panelLeft.add(new JScrollPane(editTable)); 
    JPanel panelRight = new JPanel(new BorderLayout(0, 10));

    splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, panelLeft, panelRight); 
    add(splitPane); 
    } 

    public static void main(String args[]) { 
    JFrame frame = new JFrame("One Model | Two Views"); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    frame.getContentPane().add(new SSCCE(), BorderLayout.CENTER); 
    frame.setSize(360, 240); 
    frame.setVisible(true); 
    } 
} 

Answer 1

SwingX支持在視圖圖層上配置可編輯性。無需觸摸你的模型，把它編輯酌情：

viewTable = new JXTable(model); 
viewTable.setEditable(false); 
editTable = new JXTable(model); 

Answer 2

創建WrapperTableModel從isCellEditable().

在表2設置的第一個可編輯模式，以表1和包裝模型（控股參照第一），它代表所有內TableModel的電話，但返回false 。
