Hi,

i have a Swing problem, i don't receive the "keypressed event" for "up arrow" when the Ctrl key is pressed. I have one
computer for which i receive the keyPressed, but another computer the java program doesn't work.

I keep "Ctrl" key pressed, and i type the up arrow key.

On the "working" computer:

keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_UP, modifiers = Ctrl


On the "not working" computer:

keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl
keyPressed keyCode = VK_CONTROL, modifiers = Ctrl

The "up" key is not seen. Do i misuse the Java API, or do you know any bug wich could be the cause of that behavior?


The source code:
======================================
package lc;

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

import javax.swing.DefaultListModel;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;

public class ListeClavier {

	public static void main(String[] args) {
		System.out.println("java.version : " + System.getProperty("java.version"));
		
		JFrame frame = new JFrame();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		DefaultListModel model = new DefaultListModel();
		model.addElement("a");
		model.addElement("b");
		model.addElement("c");
		
		JList list = new JList(model);
		
		list.addKeyListener(new KeyAdapter() {

			public void keyPressed(KeyEvent e) {
				String key;
				switch (e.getKeyCode()) {
				case KeyEvent.VK_UP: key = "VK_UP"; break;
				case KeyEvent.VK_DOWN: key = "VK_DOWN"; break;
				case KeyEvent.VK_CONTROL: key = "VK_CONTROL"; break;
				default: key = "" + e.getKeyCode();
				}
				System.out.println("keyPressed keyCode = " + key + ", modifiers = " + KeyEvent.getKeyModifiersText(e.getModifiers()));
			}
			
		});
		JScrollPane scrollPane = new JScrollPane(list);
		
		frame.setContentPane(scrollPane);
		frame.setVisible(true);
		
		
	}

}
=====================================

Thnaks for any help

On the "not working" computer, i have this:

At keyPressed
  ID@1 KeyEvent.KEY_PRESSED   raw KeyCode="." 17  cooked KeyChar="." 65535 CTRL_MASK
At keyPressed
  ID@1 KeyEvent.KEY_PRESSED   raw KeyCode="." 17  cooked KeyChar="." 65535 CTRL_MASK
At keyPressed
  ID@1 KeyEvent.KEY_PRESSED   raw KeyCode="." 17  cooked KeyChar="." 65535 CTRL_MASK
At keyPressed
  ID@1 KeyEvent.KEY_PRESSED   raw KeyCode="." 17  cooked KeyChar="." 65535 CTRL_MASK
At keyPressed
  ID@1 KeyEvent.KEY_PRESSED   raw KeyCode="." 17  cooked KeyChar="." 65535 CTRL_MASK
At keyReleased
  ID@2 KeyEvent.KEY_RELEASED  raw KeyCode="&" 38  cooked KeyChar="." 65535 CTRL_MASK
At keyReleased
  ID@2 KeyEvent.KEY_RELEASED  raw KeyCode="." 17  cooked KeyChar="." 65535


So the VK_UP (38) keyReleased is received, but not the keyPressed

I suspect your OS is not passing the proper keystrokes on.  You might
try updating, reinstalling, or changing your keyboard driver.  

This a longshot, but try a different keyboard.

You might also look for some non-Java tools to track keystrokes.
