Java 从不同类向JTable添加数据

所以我有一个测试客户机，它将运行这个程序，我希望这个类在一个名为StartScreenPlayerPanel的JPanel类中填充一个JTable。 我试过几种方法，但都失败了

TestClient类

import view.MainFrame;
import view.StartScreenPlayerPanel;

public class TestClientGUI {
    private static final Logger logger = Logger.getLogger(SimpleTestClientGUI.class.getName());
    private static Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
    MainFrame mainframe;
    StartScreenPlayerPanel startScreenPlayerPanel;

    public static void main(String args[]) {
        final GameEngine gameEngine = new GameEngineImpl();

        //GUI - new MainFrame

        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    MainFrame frame = new MainFrame();
                    System.out.println(screenSize);
                    frame.setMinimumSize(new Dimension(screenSize.width/2, screenSize.height/2));
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
}

使用JTable“StartScreenPlayerPanel”的类

到目前为止我所尝试的

//Add players to GUI
        StartScreenPlayerPanel startScreenPlayerPanel = new StartScreenPlayerPanel();
        startScreenPlayerPanel.setModel("CoinMaster","TheLoser");
        startScreenPlayerPanel.getModel().addRow(new Object[]{"CoinMaster", "TheLoser"});
        startScreenPlayerPanel.getModel().setValueAt("TheLoser", 2, 2);

除了在同一个班上做之外，我试过的都不管用

谢谢你的帮助

编辑-为大型机添加了代码：

public class MainFrame extends JFrame {

    static Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

    private StartScreenPlayerPanel startScreenPlayerPanel;

    private JPanel contentPane;
    private JTable table;

    /**
     * Launch the application.
     */
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    MainFrame frame = new MainFrame();
                    System.out.println(screenSize);
                    frame.setMinimumSize(new Dimension(screenSize.width/2, screenSize.height/2));
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });

        JLabel lblTitle = new JLabel("The Coin Game",SwingConstants.CENTER);
        lblTitle.setFont(new Font("Arial", Font.PLAIN, (int)screenSize.width/30));
        GridBagConstraints gbc_lblTitle = new GridBagConstraints();
        gbc_lblTitle.gridwidth = 2;
        gbc_lblTitle.insets = new Insets(0, 0, 5, 0);
        gbc_lblTitle.anchor = GridBagConstraints.NORTH;
        gbc_lblTitle.fill = GridBagConstraints.HORIZONTAL;
        gbc_lblTitle.gridx = 0;
        gbc_lblTitle.gridy = 0;
        contentPane.add(lblTitle, gbc_lblTitle);

        JPanel StartScreenBtnPanel = new JPanel();
        GridBagConstraints gbc_StartScreenBtnPanel = new GridBagConstraints();

        gbc_StartScreenBtnPanel.insets = new Insets(0, 0, 5, 0);
        gbc_StartScreenBtnPanel.fill = GridBagConstraints.BOTH;
        gbc_StartScreenBtnPanel.gridx = 0;
        gbc_StartScreenBtnPanel.gridy = 1;
        contentPane.add(StartScreenBtnPanel, gbc_StartScreenBtnPanel);
        StartScreenBtnPanel.setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5));

        JButton btnAddPlayer = new JButton("Add Player");
        btnAddPlayer.setFont(new Font("Tahoma", Font.PLAIN, 16));
        StartScreenBtnPanel.add(btnAddPlayer);

        JButton btnStartGame = new JButton("Start Game");
        btnStartGame.setFont(new Font("Tahoma", Font.PLAIN, 16));
        StartScreenBtnPanel.add(btnStartGame);


        GridBagConstraints gbc_playerPanel = new GridBagConstraints();
        gbc_playerPanel.gridwidth = 2;
        gbc_playerPanel.insets = new Insets(0, 0, 5, 0);
        gbc_playerPanel.fill = GridBagConstraints.BOTH;
        gbc_playerPanel.gridx = 0;
        gbc_playerPanel.gridy = 2;
        contentPane.add(startScreenPlayerPanel, gbc_playerPanel);

    }

    public StartScreenPlayerPanel getStartScreenPlayerPanel() {
        return startScreenPlayerPanel;
    }
}

我没有看到任何代码将StartScreenPlayerPanel添加到您的大型机中。我没有包含它们。它们会有帮助吗？是的。此外，请告诉我们您正在运行的确切代码。

TestClientGUI

是否真的声明了两个大型机变量（即

frame

和

MainFrame

）？

TestClientGUI

是否真的声明了一个它从未使用过的

startScreenPlayerPanel

字段？我怀疑您可能正在修改StartScreenPlayerPanel，它与您添加到大型机的实例不同。嘿，伙计，我添加了大型机的代码，thanksMainFrame包含自己的StartScreenPlayerPanel。删除大型机类之外的所有代码，该类包含

新的StartScreenPlayerPanel（）

。更改单独的新面板不会影响主机中的面板。
