java - 打开时JFrame“不可点击”

Question

我有一个 JFrame 打开另一个 JFrame，但是当我尝试在第二个 JFrame 弹出时单击它时，没有任何点击。问题是，如果我选择旧的 JFrame（单击它），然后选择新的，那么新的就会起作用。问题是当它弹出时我需要它工作，因为显然我不希望用户必须点击一百个地方才能让程序工作。

这是调用/创建新 JFrame 的代码：

public void displayData(ArrayList<Judge> novice, ArrayList<Judge> advanced) {
    DisplayWindow w = new DisplayWindow(novice, advanced);
    w.setLocation(this.getLocation().x+20, this.getLocation().y+20);
    w.setVisible(true);
    w.setState(JFrame.NORMAL);
}

这是“DisplayWindow”的代码（我怀疑顶部的方法与它无关，因为它们根本不直接管理 JFrame，但我仍然发布它们）：

public class DisplayWindow extends JFrame {
private JPanel contentPane;
private ArrayList<Judge> novice;
private ArrayList<Judge> advanced;

/**
 * Create the frame.
 */
public static String getSingleText(ArrayList<Judge> d) {
    StringBuilder product = new StringBuilder("");
    for (Judge j : d) {
        product.append(String.format("Judge: %s ", j.toString() + (j.getDebates().get(0).isAdvanced() ? 'A' : 'N')));
        for (Debate de : j.getDebates()) {
            product.append(String.format("Round: %s ", de != null ? de.toString() : "null"));
        }
        product.append("\n");
    }
    return product.toString();
}
public String getText(ArrayList<Judge> novice, ArrayList<Judge> advanced) {
    StringBuilder product = new StringBuilder("");
    product.append("Advanced:\n");
    product.append(getSingleText(advanced));
    product.append("\nNovice:\n");
    product.append(getSingleText(novice));
    return product.toString();
}
public DisplayWindow(ArrayList<Judge> novice, ArrayList<Judge> advanced) {
    this.novice = novice;
    this.advanced = advanced;

    setBounds(100, 100, 450, 300);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    contentPane.setLayout(new BorderLayout(0, 0));
    setContentPane(contentPane);


    JTextArea textArea = new JTextArea(getText(novice, advanced));
    textArea.setEditable(false);
    JScrollPane scroll = new JScrollPane(textArea);
    contentPane.add(scroll, BorderLayout.CENTER);

    JLabel lblNewLabel = new JLabel("Debate Calculation:");
    contentPane.add(lblNewLabel, BorderLayout.NORTH);

    JPanel panel = new JPanel();
    contentPane.add(panel, BorderLayout.SOUTH);

    JButton btnSave = new JButton("Save");
    panel.add(btnSave);
}

}

而且，以防万一，这里是旧 JFrame 的创建代码：

public DataWindow() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 450, 300);
    contentPane = new JPanel();
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    contentPane.setLayout(new BorderLayout(0, 0));
    setContentPane(contentPane);
    contentPane.setLayout(new BorderLayout(0, 0));
    setLocationRelativeTo(null);
    String[] columnNames = {"School",
            "Advanced #",
            "Novice #",
    };
    Object[][] data = {

            };  

    DefaultTableModel model = new DefaultTableModel(columnNames, 0); 
    table = new JTable(model){
        public Class getColumnClass(int column) {
            switch (column) {
                case 0:
                    return String.class;
                case 1:
                    return Integer.class;
                case 2:
                    return Integer.class;
                case 3:
                    return Integer.class;
                default:
                    return Integer.class;
            }
        }
    };
    JScrollPane scrollPane = new JScrollPane(table);
    table.setFillsViewportHeight(true);
    contentPane.add(scrollPane, BorderLayout.CENTER);


    JPanel panel = new JPanel();
    contentPane.add(panel, BorderLayout.NORTH);
    panel.setLayout(new WrapLayout(FlowLayout.CENTER, 5, 5));
    chckbxCantJudgeOwn.setSelected(true);

    panel.add(chckbxCantJudgeOwn);
    chckbxCantDebateOwn.setSelected(true);

    panel.add(chckbxCantDebateOwn);
    chckbxCantJudgeSchool.setSelected(true);

    panel.add(chckbxCantJudgeSchool);
    chckbxCantDebateSchool.setSelected(true);

    panel.add(chckbxCantDebateSchool);
    chckbxCantDebateSchool.setSelected(true);

    JPanel panel_1 = new JPanel();
    contentPane.add(panel_1, BorderLayout.SOUTH);
    panel_1.setLayout(new GridLayout(0, 2, 0, 0));

    JButton btnNewButton = new JButton("+");
    btnNewButton.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            DefaultTableModel model = (DefaultTableModel) table.getModel();
            model.addRow(new Object[]{"?????", 0, 0});
        }
    });
    panel_1.add(btnNewButton);

    JButton button = new JButton("-");
    button.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            int[] selectedRows = table.getSelectedRows();
            if (selectedRows.length > 0) {
                for (int i = selectedRows.length - 1; i >= 0; i--) {
                    DefaultTableModel model = (DefaultTableModel) table.getModel();
                    model.removeRow(selectedRows[i]);
                }
            }
        }
    });
    panel_1.add(button);

    btnCancel.setEnabled(false);
    btnCancel.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            processer.stop();
            toggleButtons();
        }
    });
    btnProcess.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            processer = new Thread(new Runnable() {
                public void run() {
                    startProcess(getData(table));                       
                }
            });
            processer.start();
            toggleButtons();

        }
    });
    panel_1.add(btnProcess);
    panel_1.add(btnCancel);
