Hi,
I have a JPanel into which JButtons are added. These JButtons can be
dragged around in the JPanel. I need to restrict the dragging so that
the JButton cannot be dragged outside the JPanel.

Here is my code

<code>
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class DragTest extends JFrame {

    private JButton jButton1;
   private JPanel jPanel1;

   public DragTest() {
       jPanel1 = new JPanel();
       jButton1 = new JButton();

       setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
       jPanel1.setLayout(null);

       jPanel1.setBackground(new Color(255, 255, 255));
       jButton1.setText("jButton1");
       jPanel1.add(jButton1);
       jButton1.setBounds(170, 160, 75, 23);
       jButton1.addMouseMotionListener(new DragHandler(this));
       getContentPane().add(jPanel1, BorderLayout.CENTER);
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
       setBounds((screenSize.width-400)/2, (screenSize.height-300)/2,
400, 300);
   }

   public static void main(String args[]) {
       EventQueue.invokeLater(new Runnable() {
           public void run() {
               new DragTest().setVisible(true);
           }
       });
   }

   class DragHandler extends MouseMotionAdapter{
       DragTest frame;
       DragHandler(DragTest frame){
           this.frame = frame;
       }

       public void mouseDragged(MouseEvent e) {
           Component c = e.getComponent();
           c.setLocation(c.getX() + e.getX()-c.getWidth()/2, c.getY()
+ e.getY()-c.getHeight()/2);
       }
   }
}

</code>

Kindly advice how i can restrict the dragging

Thanks in advance
