Just check e instanceof MouseEvent and get all the parameters from the MouseEvent

public void eventDispatched(AWTEvent e) { 
  if (e instanceof MouseEvent) {
    MouseEvent  me=(MouseEvent)e;
  } 
}

long KEY_EVENTS = AWTEvent.KEY_EVENT_MASK;
long MOUSE_EVENTS = AWTEvent.MOUSE_EVENT_MASK;
long MOUSE_MOTION_EVENTS = AWTEvent.MOUSE_MOTION_EVENT_MASK;

code for correct suggestion by @StanislavL

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

class ClosingFrame extends JFrame {

    private static final long serialVersionUID = 1L;
    private AWTEventListener awt;

    public ClosingFrame() {
        setName("Dialog ... ClosingFrame");
        JButton b = new JButton("<html>close dialog.  <br>enter this button from <br>"
                + "the top to get the <br>hoverhelp close enough<br>to cause problems<html>");
        b.setName("buttonToPress");
        b.setToolTipText("<html>111111111111111111111"
                + "1111111111111111111111111111111111111111111<br></html>");
        b.addActionListener(closeActionListener);
        add(b);
        JPopupMenu menu = new JPopupMenu();
        menu.add("some item ...........");

    };

    public static void main(String args[]) {
