Draging a JLabel

Question

Hi I have a problem while draging a JLabel in a JFrame, could someone help me here's the code. While draging I loose control of the JLabel + the cursor doesn't stay with the JLabel
2 classes:
test.java
MoveLabel.java
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import java.util.*;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;
import javax.swing.JLabel;
class testMove
public static void main (String[] args)
final JFrame frame = new JFrame("Prototype");
final MoveLabel lmv = new MoveLabel();
frame.getContentPane().add(lmv);
frame.setSize(500,500);
frame.setVisible(true);
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import java.util.*;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;
import javax.swing.JLabel;
class MoveLabel extends JLabel implements MouseListener, MouseMotionListener
public int x;
public int y;
public int mx;
public int my;
public int new_mx;
public int new_my;
public MoveLabel()
// super("Print", icon, JLabel.CENTER);
this.setIcon(new ImageIcon("print.jpg"));
this.addMouseListener(this);
this.addMouseMotionListener(this);
public void mouseClicked(MouseEvent e)
if (e.getClickCount() == 2)
System.out.println("You have DoubleClicked ");
public void mouseDragged(MouseEvent e)
new_mx = e.getX();
new_my = e.getY();
x += new_mx - mx;
y += new_my - my;
System.out.println("depl de " + x +" y " + y);
this.setText("Printing");
this.setLocation(x,y);
mx = new_mx;
my = new_my;
public void mouseMoved(MouseEvent e)
public void mousePressed(MouseEvent e)
mx = e.getX() ;
my = e.getY() ;
this.setText("Printing");
public void mouseReleased(MouseEvent e)
System.out.println("You have released at " + e.getX()+ " " + e.getY());
public void mouseEntered(MouseEvent e)
public void mouseExited(MouseEvent e)
}

I changed some codes in your original program. It works now.
