Answer 1

Create a javax.swing.Timer that has a 5 second initial
delay, non-repeating. When it fires, it should hide
the cursor (set to a blank cursor or whatever you have
to do). Then on mouse motion events, you show the
cursor and reset the timer.A good idea - is there no mouseNotMoved-event ?
heres my sample-code:import java.awt.*;
import java.awt.event.*;
import java.awt.image.MemoryImageSource;
import javax.swing.*;
import javax.swing.event.MouseInputAdapter;
public class HiddenCursorListener extends MouseInputAdapter implements ActionListener {
     private static final Cursor HIDDEN_CURSOR =
          Toolkit.getDefaultToolkit().createCustomCursor(
               Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(16, 16, new int[16 * 16], 0, 16)),
               new Point(0, 0),
               "HIDDEN_CURSOR");
     private static final Cursor DEFAULT_CURSOR = new Cursor(Cursor.DEFAULT_CURSOR);
     private Timer timer;
     private int timerDelay=1000;
     private Window window;
     public HiddenCursorListener(Window win) {
          window=win;     
     public void mouseEntered(MouseEvent e){
          startTimer();
     public void mouseMoved(MouseEvent e) {
          showCursor();
     public void mouseDragged(MouseEvent e) {
          showCursor();
     public void mouseClicked(MouseEvent e){
          showCursor();
     public void actionPerformed(ActionEvent e) {
          hideCursor();
     private void hideCursor(){
          if (window.getCursor() != HIDDEN_CURSOR)
               window.setCursor(HIDDEN_CURSOR);
     private void showCursor(){
          if (window.getCursor() != DEFAULT_CURSOR)
               window.setCursor(DEFAULT_CURSOR);
     private void startTimer(){
          timer = new Timer(timerDelay, this);
          timer.start();
     public static void main(String[] args) {
          JFrame f = new JFrame("Hidden-Cursor-Test");
          f.setSize(500, 500);
          f.setLocationRelativeTo(null);
          f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          HiddenCursorListener lis = new HiddenCursorListener(f);
          f.addMouseMotionListener(lis);
          f.addMouseListener(lis);
          f.setVisible(true);
}regards
