My problem with this code is that when I run it the JMenuItem
doesn't appear. I'm so confused! Anyone can help?
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class NewClass extends JFrame implements ActionListener{
JFrame window = new JFrame("Ηλεκτρονικό Έντυπο Υπερωριών");
JMenu menu = new JMenu("Example");
JMenuItem menuItem = new JMenuItem("hi");
public NewClass(){
window.setSize(200,200);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
menu.add(menuItem);
menuItem.addActionListener(this);
window.add(menu);
window.pack();
window.setVisible(true);
}
public static void main(String []args){
NewClass example = new NewClass();
}
@Override
public void actionPerformed(ActionEvent ae) {
throw new UnsupportedOperationException("Not supported yet.");
}
}
You need to add a menubar to the window. To this menubar you add your menu(s). Take a look at oracle's tutorial on How to Use Menus.
