Hi, I'm Nescafe. This is my first time to the forums. I'm a sophomore in college and intending to go into CPSC in the near future. Nonetheless, my breadth of knowledge concerning Java is still limited thought it is the language I have had the most experience with.

Below is some code I recently wrote. I am intending to write a simple GUI that will report when the mouse enters my JPanel component, exits the component and while within the component reports the points of the mouse pointer. I have been successful with the first two scenarios but can't get the mouse point of the mouse pointer. I extended the MouseAdapter class and I thought that the mouseMoved() method would be called when the mouse is within my component. However, this does not seem to be the case.

Furthermore, on a side not, you will see that I commented out an anonymouse class I had with in my constructor. Is this a good idea? Is the anonymouse class a bad idea w/in the constructor as oppsed to creating the inner class that I have: MouseMotionListener. In other words, do you guys have any reccomendations on how to structure to code in a better way, i.e. better structure, etc? Sorry about the long post but thanks for the help!!

HTML Code:
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;

public class MouseMotion{
	private JPanel mousePanel;
	private JFrame frame;
	private JLabel mouseLabel;
	public MouseMotion(){
		frame = new JFrame("Moust Motion Listener");
		frame.setLayout(new BorderLayout());
		mouseLabel = new JLabel("Listening for mouse movement......");
		//add border to mouseLabel
		//mouseLabel.setBorder(BorderFactory.createTitledBorder("Is Mouse Moving?"));
		mousePanel = new JPanel();
		//setPreferredSize-- not working correctly!!
		mousePanel.setSize(new Dimension(
									frame.getWidth(), frame.getHeight() * (1/3)));
		//add mouse listener to panel
		mousePanel.addMouseListener(new MouseMoveListener());
		mousePanel.addMouseListener(new MouseAdapter(){
			public void mouseEntered(MouseEvent evt){
				//System.out.println("mouse entered component");
				mouseLabel.setText("Mouse entered component");
			public void mouseExited(MouseEvent evt){
				mouseLabel.setText("<html>Mouse has <font color = red>left </font>component</html>");
		frame.getContentPane().add(mousePanel, BorderLayout.CENTER);
		frame.getContentPane().add(mouseLabel, BorderLayout.SOUTH);
		//add border to JLabel later
//MouseAdapter class	
	private class MouseMoveListener extends MouseAdapter{
		public void mouseEntered(MouseEvent evt){
			mouseLabel.setText("<html>Mouse has <font color = blue>entered</font> component</html>");
		public void mouseExited(MouseEvent evt){
			mouseLabel.setText("<html>Mouse has <font color = red>exited</font> component</html>");
		public void mouseMoved(MouseEvent evt){
			//System.out.println("mouseMoved event");
	public static void main(String[] args){
		new MouseMotion();
