Hi all !

I'm facing some problem with com.jogamp.newt.event.KeyEvent.

To be more specific, com.jogamp.newt.event.KeyEvent does not act like java.awt.event.KeyEvent !

Context :
On 2 sample programs using NEWT and AWT (see code under), using my french keyboard, i'm trying to type "î".
On any application (like firefox), with my keyboard, i have to press [^] then [i] in order to print "î".

Experiment :
Using the AWT sample, with a java.awt.Frame and java.awt.KeyEvent, the getKeyChar() method of the second keyevent (when pressing [i]) returns "î".
Using the NEWT sample, with a com.jogamp.newt.opengl.GLWindow and com.jogamp.newt.event.KeyEvent, the getKeyChar() method of the second keyevent returns "i" (instead of "î").

Am i doing something wrong or it is a limitation of com.jogamp.newt.event.KeyEvent ?

I'm using jogl candidate jars (dated 14 december 2010).

Sample NEWT :

package test.keyevent;

import javax.media.opengl.GLCapabilities;
import javax.media.opengl.GLProfile;

import com.jogamp.newt.event.KeyEvent;
import com.jogamp.newt.event.KeyListener;
import com.jogamp.newt.event.WindowAdapter;
import com.jogamp.newt.event.WindowEvent;
import com.jogamp.newt.opengl.GLWindow;

public class NEWTKeyEventDemo implements KeyListener {
	
	public void keyTyped(KeyEvent e) {
    	System.out.println("[keyTyped] keychar : "+ e.getKeyChar());
    }

    public void keyPressed(KeyEvent e) {
    	System.out.println("[keyPressed] keychar : "+ e.getKeyChar());
    }

    public void keyReleased(KeyEvent e) {
    	System.out.println("[keyReleased] keychar : "+ e.getKeyChar());
    }

    public static void main(String[] args) throws InterruptedException {
    	// create listener
    	NEWTKeyEventDemo demo = new NEWTKeyEventDemo();
    	
        // create and set up the window
    	GLProfile.initSingleton(false);        
        GLCapabilities caps = new GLCapabilities(GLProfile.getDefault());
    	GLWindow window = GLWindow.create(caps);
        window.setSize(320, 240);
        window.setVisible(true);
        window.setTitle("BDiDemoWidgets");   
        window.addWindowListener(new WindowAdapter() {
            public void windowDestroyNotify(WindowEvent arg0) {
                System.exit(0);
            };
        });
        
        window.addKeyListener(demo);
        
        while(true)
			Thread.sleep(1000);
    }
}

Sample AWT :

package test.keyevent;

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

import javax.swing.JFrame;


public class AWTKeyEventDemo implements KeyListener {

    public void keyTyped(KeyEvent e) {
    	System.out.println("[keyTyped] keychar : "+ e.getKeyChar());
    }

    public void keyPressed(KeyEvent e) {
    	System.out.println("[keyPressed] keychar : "+ e.getKeyChar());
    }

    public void keyReleased(KeyEvent e) {
    	System.out.println("[keyReleased] keychar : "+ e.getKeyChar());
    }

    public static void main(String[] args) {
    	// create listener
    	AWTKeyEventDemo demo = new AWTKeyEventDemo();
    	
        //Create and set up the window.
    	JFrame frame = new JFrame("KeyEventDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        //Display the window.
        frame.setSize(320, 240);
        frame.setVisible(true);
        
        frame.addKeyListener(demo);
    }
}
