Keyboard indicator

[Pavlo]

Hi all!

I'm trying to make keyboard indicator for Win XP/7 (just like in windows tray) which will be moved with mouse pointer. I make JFform with JLabel.
Also I find how to know what current language is by:

        import java.awt.im.InputContext;
        ...
        InputContext KeyboardLayout = InputContext.getInstance();
        String lang = KeyboardLayout.getLocale().getLanguage();

The question is how to let know the application about language change and reload label text? (notice that user can change input language in any other applications by predefined keys or mouse). I find some info ... may be use windows API? or may be Java is not good for such tasks? What direction to choose?

Source:

package showlayout3;

import java.awt.*;
import java.awt.im.InputContext;
import javax.swing.border.*;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class ShowLayout3 {
    public static void main(String[] args) {
        JFrame frame = new JFrame ("Layout");
        InputContext keyboard_layout= InputContext.getInstance();
        String lang = keyboard_layout.getLocale().getLanguage();
        
        final JLabel label = new JLabel(lang);
        label.setBorder(new LineBorder(Color.blue,1));
        
        label.setFont(new Font(label.getFont().getName(),Font.PLAIN,64));
        frame.getContentPane().add(label);
        
        frame.setSize(300,300);
        frame.setLocation(300,800);
        frame.setUndecorated(true);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}
