A mouse released event is gauranteed to occur in the same component as the mouse pressed event. It sounds like you are trying to implement some sort of drag and drop function. You may want to think about using the standard dnd ability.

Now... you might be able to cheat by adding a MouseListener to the Container of the 2 tables and then using "getComponentAt(int x, int y)" to check the component under the event.

Hope this helps...

Here is some demo code...


import javax.swing.*;
import javax.swing.border.LineBorder;
import java.awt.*;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

/**
* <pre>
* Test
* </pre>
*/
public class Test {
public static void main(String[] args) {
JFrame test = new JFrame(&quot;Test Window&quot;
test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
test.getContentPane().setLayout(new BorderLayout(0, 0));

final JLabel lbl1 = new JLabel(&quot;DRAG HERE&quot;
lbl1.setBorder(new LineBorder(Color.black, 1));
final JLabel lbl2 = new JLabel(&quot;DROP HERE&quot;
lbl2.setBorder(new LineBorder(Color.black, 1));

final JPanel p = new JPanel();
p.add(lbl1);
p.add(lbl2);
p.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
Component c = p.getComponentAt(e.getX(), e.getY());
System.out.println(&quot;IS DRAG? &quot; + (lbl1 == c));
}

public void mouseReleased(MouseEvent e) {
Component c = p.getComponentAt(e.getX(), e.getY());
System.out.println(&quot;IS DROP? &quot; + (lbl2 == c));
}
});

test.getContentPane().add(p);

test.pack();
test.setVisible(true);
}
}
