我正在制作一个Java应用程序,用于修补mod并将纹理包添加到Minecraft中。我希望它使用通过DJ Project JWebBrowser访问的在线Mod商店。我正在使用Eclipse WindowBuilder /手工编码来构造UI。我的问题是WindowBuilder崩溃并出现以下错误

奇怪的是,如果我正常运行它就可以正常工作。这是相关的源代码:

        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();
            }

                    error(e);

        setDefaultCloseOperation(DISPOSE_ON_CLOSE);
        pack();


当我在这里时,mntmQuit按钮没有任何作用。我调试了它,当我单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,任何帮助将不胜感激!

最佳答案

我可以回答您一半的问题-也许我会澄清,其余的问题。

您需要将ActionListener附加到JMenuItem,而不是MouseListener。有关一些非常好的示例,请参见Oracle教程How to Use Menus
