Localized accelerators (JMenuItem hotkeys) in Swing

问题

I am working in an English app on a german laptop, over a spanish OS.

Even if I explictly set Locale.setDefault(Locale.ENGLISH) at the beggining of my app, I am seeing the hotkexs in the menu as

CTRL + Mayúsculas + C 

instead of

CTRL + SHIFT + C 

that I passed to the KeyStroke object.

Is not only that word does not get localized to english as I specified, but also that it maps SHIFT key to MAYUS (CAPS LOCK in english), so I guess this is not only a language issue, but keymap´s as well.

So how can I impose english for all the GUI components?

Thank you!

You have to make sure that you set the locale before any toolkit code is executed. The following code shows the effect: if you move the Locale.setDefault(Locale.GERMAN); to any other line it will show the default accelerator names again.

Instead of setting the locale inside your code you may also append the following argument to the VM:

-Duser.language=DE

public class MenuLocale {

    public static void main(String[] args) {
        Locale.setDefault(Locale.GERMAN);
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JFrame f = new JFrame();
                f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

                JMenuBar menubar = new JMenuBar();
                JMenu menu = new JMenu("Menu");
                JMenuItem menuitem = new JMenuItem("Menuitem");    
                menuitem.setAccelerator(KeyStroke.getKeyStroke('X', KeyEvent.CTRL_MASK | KeyEvent.SHIFT_MASK));

                f.setJMenuBar(menubar);
                menubar.add(menu);
                menu.add(menuitem);

                f.pack();
                f.setVisible(true);
            }
        });
    }
}
