I have several labels and buttons in an applications and would like to detect a right mouse button click.  I have looked through the web but can find nothing suitable.  I would like to be able to detect a right click on anyone of the buttons or labels and then go to a function/method to do my business.  I am using Netbeans but can put code in if someone can suggest some code.  Thanks.

Just add a MouseListener that listens for right-clicks to any component you're interested in:

import java.awt.*;
import java.awt.event.*;

import java.io.*;

import java.util.*;

import javax.swing.*;


public class F extends JFrame {
    private void setGui() {
        try {
            setLocation(0, 100);
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            Container cp = getContentPane();
            cp.setLayout(new FlowLayout());

            JLabel label = new JLabel("Right-click me!");
            label.addMouseListener(new RightClickListener());
            cp.add(label);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        try {
            SwingUtilities.invokeAndWait(new Runnable() {
                    public void run() {
                        F f = new F();
                        f.setGui();
                        f.setSize(200, 200);
                        f.setVisible(true);
                    }
                });
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

    private class RightClickListener extends MouseAdapter {
        public void mouseClicked(MouseEvent e) {
            if ((e.getModifiers() & InputEvent.BUTTON3_MASK) == InputEvent.BUTTON3_MASK) {
                System.out.println("Right-clicked");
            }
        }
    }
}

Just as a helpful comment : all questions in the Java TA are about "Java Programming", so it would be in your interest, I'd say, to provide a little more detail on the issue via the question title. It makes it archivally more recoverable too.

Perfect, Thank you CEHJ!  Exactly what I was looking for.  I made several mods but the basics is what I needed.  And thanks for the added tip about posting.
