I want to generate KeyEvents from a JPanel. I have tried the
following code (taken in part from the CoreJava Volume1 -
Fundamentals - 1.2 edition - chapter 8 page 341), which does
override the isFocusTraversable method to return 'true' for the
panel.

I compiled this code under Solaris (details as in section 5)
but it doesn't work. However, the Solaris-compiled code does
work on Windows NT (Pentium II).

Why is there a difference and is there a workround?



import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

class SketchPanel extends JPanel implements KeyListener {
public SketchPanel() {
addKeyListener(this);
}

public void keyPressed(KeyEvent evt) {
System.out.println("SSSSS");
int keyCode = evt.getKeyCode();
int modifiers = evt.getModifiers();
System.out.println(keyCode);
System.out.println(modifiers);
}

public void keyReleased(KeyEvent evt) {}

public void keyTyped(KeyEvent evt) {}

public boolean isFocusTraversable() {
return true;
}

}

class SketchFrame extends JFrame {
public SketchFrame() {
setTitle("Test");
setSize(300,200);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
} );

Container contentPane = getContentPane();
contentPane.add(new SketchPanel());
}
}

public class Sketch {
public static void main(String[] args) {
SketchFrame frame = new SketchFrame();
frame.show();
}
}
