How to import an image in menu bar

I've created a simple menu bar and I don't know how to import an image in the free space.

My code is below:

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

public class MyMenu extends JFrame {

    JMenuBar menubar;
    JMenu file, edit, contact, quit;
    JMenuItem exit, open, search, delete, registration, informations;

    public MyMenu() {
        setLayout(new FlowLayout());
        //___________________________ FILE __________________________________
        menubar = new JMenuBar();
        setJMenuBar(menubar);
        file = new JMenu("Αρχείο");
        menubar.add(file);
        open = new JMenuItem("Άνοιγμα πελατολογίου");
        file.add(open);
        event e1 = new event(); // Compiler Error
        open.addActionListener(e1);
        //__________________________________ EDIT ____________________________
        edit = new JMenu("Ενέργειες");
        menubar.add(edit);
        search = new JMenuItem("Αναζήτηση");
        edit.add(search);
        registration = new JMenuItem("Καταχώρηση");
        edit.add(registration);
        delete = new JMenuItem("Διαγραφή");
        edit.add(delete);
        //_________________________________ CONTACT __________________________
        contact = new JMenu("Επικοινωνία");
        menubar.add(contact);
        informations = new JMenuItem("Πληροφορίες");
        contact.add(informations);
        //___________________________________QUIT_____________________________
        quit = new JMenu("Έξοδος");
        menubar.add(quit);
        exit = new JMenuItem("Έξοδος");
        quit.add(exit);
        event e = new event(); // Compiler Error
        exit.addActionListener(e);
    }

    public class MyEvent implements ActionListener {

        public void actionPerformed(ActionEvent e) {
            System.exit(0);
        }

        public void actionPerformed2(ActionEvent e1) {
            final SimpleTableDemo a = new SimpleTableDemo(); // Compiler Error
            javax.swing.SwingUtilities.invokeLater(new Runnable() {

                public void run() {
                    a.createAndShowGUI();
                }
            });
        }
    }

    public static void main(String[] args) throws IOException {
        MyMenu gui = new MyMenu();
        gui.getContentPane().add(panel); // Compiler Error
        gui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        gui.setSize(2400, 1900);
        gui.setVisible(true);
    }
}

It is related to the class Panel? How can I take advantage of the free space and use an image?

回答1:

please post here Runnable code without Errors from Java Compilator (marked in you code with // Compiler Error) before any of your request for AddingImage / ImportImage in JMenuBar

required tutorials

1) JMenu, JMenuBar, JMenuItems

2) Laying Out Components Within a Container

3) How to Write an Action Listener

4) How to Use Icons

5) and finally for set Image as JMenuBar BackGround you have to read something about 2D Graphics

6) examples on this forum, here or here

回答2:

A JMenuItem can be constructed in order to display an image.

ImageIcon icon = new ImageIcon("path_to_your_image");
JMenuItem item = new JMenuItem(icon);
