package net.sourcecodeexamples.swingexamples.menus;

import java.awt.EventQueue;
import java.awt.event.KeyEvent;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;

public class SimpleMenuExample extends JFrame {

    private static final long serialVersionUID = 1 L;

    private void initializeUI() {

        createMenuBar();

        setTitle("Simple menu");
        setSize(350, 250);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }

    private void createMenuBar() {

        JMenuBar menuBar = new JMenuBar();
        ImageIcon exitIcon = new ImageIcon("src/resources/exit.png");

        JMenu fileMenu = new JMenu("File");
        fileMenu.setMnemonic(KeyEvent.VK_F);

        JMenuItem eMenuItem1 = new JMenuItem("Stop", exitIcon);
        eMenuItem1.setMnemonic(KeyEvent.VK_E);
        eMenuItem1.setToolTipText("Stop application");
        eMenuItem1.addActionListener((event) - > System.exit(0));

        JMenuItem eMenuItem = new JMenuItem("Exit", exitIcon);
        eMenuItem.setMnemonic(KeyEvent.VK_E);
        eMenuItem.setToolTipText("Exit application");
        eMenuItem.addActionListener((event) - > System.exit(0));

        fileMenu.add(eMenuItem);
        fileMenu.add(eMenuItem1);
        menuBar.add(fileMenu);

        setJMenuBar(menuBar);
    }

    public static void main(String[] args) {

        EventQueue.invokeLater(() - > {
            SimpleMenuExample simpleMenuExample = new SimpleMenuExample();
            simpleMenuExample.initializeUI();
            simpleMenuExample.setVisible(true);
        });
    }
