java - 物质和 MacOS 菜单栏

Question

我有一个扩展 JFrame 的 MainWindow 类。 在 MainWindow 中我有一个 JMenuBar。

我想在 OSX 中将菜单栏显示在顶部(Apple 符号旁边)。这仅在我未设置 Substance Skin 时有效。是否可以使用 Substance Skin 并使用 MacOS 菜单栏？

我的代码:

//Set Menu for MacOS
System.setProperty("apple.laf.useScreenMenuBar", "true");
System.setProperty("com.apple.mrj.application.apple.menu.about.name", name);

try {
    SwingUtilities.invokeAndWait(new Runnable() {  
        public void run() {
            SubstanceSkin skin = new GraphiteGlassSkin();
            SubstanceLookAndFeel.setSkin(skin); //WORKS WHEN I COMMENT THIS (WITHOUT SUBSTANCE SKIN)
            JFrame.setDefaultLookAndFeelDecorated(false);
            MainWindow mainWindow = new MainWindow(name);
            mainWindow.setVisible(true);
        }  
    });
} catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (InvocationTargetException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

您可以像这样单独指定菜单栏的 UI:

                try {
                    UIManager.setLookAndFeel(new SubstanceBusinessBlackSteelLookAndFeel());
                } catch (UnsupportedLookAndFeelException ex) {
                    // log...
                }

                JMenuBar menubar = frame.getJMenuBar(); // assuming you've set the menu bar already
                String os = System.getProperty("os.name");

                if (os.equals("Mac OS X")) {
                    try {
                        System.setProperty("apple.laf.useScreenMenuBar", "true");
                        menubar.setUI((MenuBarUI) Class.forName("com.apple.laf.AquaMenuBarUI").newInstance());
                    } catch (Exception ex) {
                        // log...
                    }
                }
