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：
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
public void mouseClicked(MouseEvent arg0) {
try {
Config.restoreDefualts();
updateSettings();
} catch (Exception e) {
e.printStackTrace();
error(e);
}
}
});

tabSettings.setLayout(gl_tabSettings);
JPanel statusBar = new JPanel();
statusBar.setToolTipText("Status");
getContentPane().add(statusBar, BorderLayout.SOUTH);
setIconImage(Toolkit.getDefaultToolkit().getImage(
OpenMPatch.class.getResource("/alex/mik/openmpatch/icon.png")));
JMenuBar menuBar = new JMenuBar();
setJMenuBar(menuBar);
JMenu mnFile = new JMenu("File");
menuBar.add(mnFile);
JMenuItem mntmOpenFile = new JMenuItem("Open File...");
mntmOpenFile.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent paramMouseEvent) {
}
});
mntmOpenFile.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_O,
InputEvent.CTRL_MASK));
mnFile.add(mntmOpenFile);
JMenuItem mntmOpenFolder = new JMenuItem("Open Folder...");
mntmOpenFolder.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_O,
InputEvent.CTRL_MASK | InputEvent.SHIFT_MASK));
mnFile.add(mntmOpenFolder);
JSeparator fileSeparator1 = new JSeparator();
mnFile.add(fileSeparator1);
JMenuItem mntmQuit = new JMenuItem("Quit");
mntmQuit.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent arg0) {
close();
}
});
mntmQuit.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_Q,
InputEvent.CTRL_MASK));
mnFile.add(mntmQuit);
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。
