jtable列中的复选框org.jdesktop.beansbinding无法编辑

问题描述

需要编辑使用JcheckBox。我正在使用JTablebinding填充数据。 预期的行为是从复选框中获取输入并更新原始列表。 我尝试同时添加CellEditor和Cellrenderer，但是该复选框不可编辑。 下面是我编写的示例应用程序。请帮忙。

public class MyDialog extends JFrame
{
  private JTable table = new JTable();

  public MyDialog() throws HeadlessException
  {
    JScrollPane scrollPane = new JScrollPane();
    scrollPane.setViewportView(table);

    //add the table to the frame
    this.add(scrollPane);

    this.setTitle("Table Example");
    this.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
    this.pack();
    this.setVisible(true);

    initDataBindings();
    postBindings();
  }

  private void initDataBindings()
  {

    // create the peopel List
    List<DataWrapper> people = new ArrayList<>();
    people.add(new DataWrapper(true,"John"));
    people.add(new DataWrapper(false,"Rambo"));

    // create the binding from List to JTable
    JTableBinding tb = SwingBindings.createJTableBinding(AutoBinding.UpdateStrategy.READ_WRITE,people,table);

    // define the properties to be used for the columns
    ObjectProperty<DataWrapper> selected = ObjectProperty.create();
    BeanProperty name = BeanProperty.create("name");

    // configure how the properties map to columns
    tb.addColumnBinding(selected).setColumnName("Selected");
    tb.addColumnBinding(name).setColumnName("Last Name");

    // realize the binding
    tb.bind();

  }

  private void postBindings()
  {
    table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

    final TableColumnModel columnModel = table.getColumnModel();
    TableColumn column0 = columnModel.getColumn(0);
    
    column0.setCellRenderer(new DefaultTableCellRenderer()
    {
      JCheckBox checkBox = new JCheckBox();

      @Override
      public Component getTableCellRendererComponent(JTable jTable,Object o,boolean b,boolean b1,int i,int i1)
      {
        if (o != null)
        {
          DataWrapper dataWrapper = (DataWrapper) o;

          checkBox.setSelected(dataWrapper.isSelected());

          return checkBox;
        }

        return super.getTableCellRendererComponent(jTable,o,b,b1,i,i1);
      }
    });
  }
}

public class DataWrapper
{

  private final String name;

  private boolean selected;

  public DataWrapper(boolean selected,String name)
  {
    this.selected = selected;
    this.name = name;
  }

  public String getName()
  {
    return name;
  }

  public boolean isSelected()
  {
    return selected;
  }
}
