How can I make a window popup here with swing?


I am trying to make an app similar to the attached, where I have a menu bar.

When I click on an item in the menu bar, in this case Add Client,  how can I make the add client window will appear with the contents of that window? Can someone please just list list a little example?


import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;

public class MenuExp extends JFrame {
    public MenuExp() {
        setTitle("Menu Example");
        setSize(1024, 768);
        // Creates a menubar for a JFrame
        JMenuBar menuBar = new JMenuBar();
        // Add the menubar to the frame
        // Define and add two drop down menu to the menubar
        JMenu fileMenu = new JMenu("File");
       // JMenu editMenu = new JMenu("Edit");
        // Create and add simple menu item to one of the drop down menu
        JMenuItem addClientAction = new JMenuItem("Add Client");
        JMenuItem editClientAction = new JMenuItem("Edit Client");
        JMenuItem exitAction = new JMenuItem("Exit");

        // Add a listener to the New menu item. actionPerformed() method will
        // invoked, if user triggred this menu item
        addClientAction.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
                System.out.println("You have clicked on the add new client");
    public static void main(String[] args) {
        MenuExp me = new MenuExp();

Woops!  So in other words use JOptionPane?

JDialog in conjunction with JOptionPane gives you the facility to create custom interfaces yes.  Take a look at the API lit for JDialog for more detail.

Also, what is your opinion on using NetBeans for something like this?

I have toyed with it, but for some reason it seems as if the code style is A LOT different than doing it this way.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

I don't know about Netbeans, sorry. I don't use IDEs. ;(

>> Also, what is your opinion on using NetBeans for something like this?
I don't use NetBeans neither.
But I'd like to say that code generation is all a matter of taste.
You can write functionally identical code in a dozen of ways.
If NetBeans generates code that you can read and understand it's okay.
If it doesn't then don't use it and write your own.
