java - Eclipse WindowBuilder 错误？

Question

我正在制作一个 Java 应用程序，用于修补模组并将纹理包添加到 Minecraft 中。我希望它使用通过 DJ 项目 JWebBrowser 访问的在线模组商店。我正在使用 Eclipse WindowBuilder/手动编码来构建 UI。我的问题是 WindowBuilder 因以下错误而崩溃

奇怪的是，如果我正常运行它，它就可以正常工作。这是相关的源代码:

setTitle("OpenMPatch");
        getContentPane().setLayout(new BorderLayout(0, 0));

        JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.TOP);
        getContentPane().add(tabbedPane);

        JPanel tabModStore = new JPanel();
        tabbedPane.addTab("Mod Store", null, tabModStore, "Mod Store");

        JWebBrowser modStore = new JWebBrowser();
        modStore.setStatusBarVisible(false);
        tabModStore.add(modStore);

        JPanel tabSettings = new JPanel();
        tabbedPane.addTab("Settings", null, tabSettings, "Settings");

        comboBoxTheme = new JComboBox();
        comboBoxTheme.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
                setLAF(comboBoxTheme.getSelectedItem().toString());
            }
        });
        comboBoxTheme.setModel(new DefaultComboBoxModel(new String[] {
                "system", "java", "motif", "nimbus", "windows",
                "windowsclassic" }));
        try {
            comboBoxTheme.setSelectedItem(Config.ReadConfig().get("LAF"));
        } catch (Exception e) {
            e.printStackTrace();
            OpenMPatch.error(e);
        }

        JLabel lblTheme = new JLabel("Theme:");
        lblTheme.setLabelFor(comboBoxTheme);
        lblTheme.setFont(new Font("Tahoma", Font.PLAIN, 12));
        lblTheme.setHorizontalAlignment(SwingConstants.RIGHT);

        JButton btnSaveSettings = new JButton("Save Settings");
        btnSaveSettings.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent arg0) {
                saveSettings();
            }
        });

        JButton btnRestoreDefualts = new JButton("Restore Defualts");
        btnRestoreDefualts.addMouseListener(new MouseAdapter() {
            @Override

                try {
                    Config.restoreDefualts();
                    updateSettings();

                    error(e);
                }
            }

        pack();

当我在这里时，mntmQuit 按钮没有做任何事情。我调试了它，当我点击它时它甚至没有运行 mouseClicked 事件。我正在使用 java 1.6、WindowBuilder 1.2.0.r37、Eclipse Indigo，如有任何帮助，我们将不胜感激!

我可以回答你一半的问题 - 也许通过澄清我会弄清楚剩下的问题。

您需要将 ActionListener 附加到 JMenuItem，而不是 MouseListener。请参阅 Oracle 教程 How to Use Menus一些很好的例子。
