java - 更新数据时刷新 JTable

Question

下面是我的代码:-

public class MainScreen extends javax.swing.JFrame {

    private TableRowSorter<TableModel> sorter;

    public MainScreen() {
        initComponents();
        this.setSize(java.awt.Toolkit.getDefaultToolkit().getScreenSize());

        sorter = new TableRowSorter<>(tblCustomer.getModel());
        tblCustomer.setRowSorter(sorter);
        List<BasicDetailsDTO> findAll = UtilDAO.getDaoBasicDetails().findAll();
        System.out.println("I'm here  "+findAll.size());


        ((DefaultTableModel) tblCustomer.getModel()).setDataVector(getDataVector(findAll), getVectorHeader());
        tblCustomer.setAutoCreateRowSorter(true);
        tblCustomer.getColumnModel().getColumn(0).setMinWidth(0);
        tblCustomer.getColumnModel().getColumn(0).setMaxWidth(0);

    }

    public static Vector getDataVector(List<BasicDetailsDTO> listData) {
        Vector dataVector = new Vector();
        for (BasicDetailsDTO instance : listData) {
            Vector row = new Vector();
            row.add(instance.getId());
            row.add(instance.getParticulars());
            row.add(instance.getBookedBy());
            row.add(instance.getContactPerson());
            row.add(instance.getMobileNo());
            row.add(instance.getEmail_id());
            dataVector.add(row);

        }
        return dataVector;

    }

    public static Vector getVectorHeader() {

        Vector header = new Vector();
        header.add("ID");
        header.add("Particulars");
        header.add("BOOKED BY");
        header.add("CONTACT PERSON");
        header.add("MOBILE NO");

每当我更新表中的数据时，更新的数据都不会反射(reflect)。仅当我重新打开窗口时，才会反射(reflect)更新的数据。 请帮助我度过难关。 提前致谢。

Answer 1

1. 为什么 DefaultTableModel 和 JTableHeader 的 void 是静态的

2. 从 DefaultTableModel 中删除行

3. 对 RowFilter 使用 DocumentListener 而不是 KeyListener

4. 为什么初始化了两个不同的LookAndFeel

5. 对 DefaultTableModel 的更新必须在 EDT 上完成，更多信息请参见 Oracle 教程 Concurrency in Swing - The Event Dispatch Thread

6. 搜索 ResultSetTableModel、TableFromDatabase、BeanTableModel

7. 其余问题隐藏在遮蔽 void 或类中，请注意删除所有静态声明，应该只有静态主类
