MenuTest.java - AWT Menu Test Program
This section provides a tutorial example on how to use the java.awt.Menu class to create multiple menus and how to add them to the menu bar. Sub menus and menu items added to a menu will be listed vertically when the menu is selected.
Here is an example program I wrote to test the java.awt.Menu class:
/* MenuTest.java * Copyright (c) 1997-2024 HerongYang.com. All Rights Reserved. */ import java.awt.Frame; import java.awt.MenuBar; import java.awt.Menu; import java.awt.MenuItem; public class MenuTest { Frame myFrame = null; public static void main(String[] a) { (new MenuTest()).test(); } private void test() { myFrame = new Frame("Menu Test"); myFrame.setBounds(50,50,250,150); MenuBar myMenuBar = new MenuBar(); Menu myMenu = getFileMenu(); myMenuBar.add(myMenu); myMenu = getColorMenu(); myMenuBar.add(myMenu); myFrame.setMenuBar(myMenuBar); myFrame.setVisible(true); } private Menu getFileMenu() { Menu myMenu = new Menu("File"); Menu mySubMenu = getOpenMenu(); myMenu.add(mySubMenu); MenuItem myItem = new MenuItem("Close"); myMenu.add(myItem); myMenu.addSeparator(); myItem = new MenuItem("Exit"); myMenu.add(myItem); return myMenu; } private Menu getColorMenu() { Menu myMenu = new Menu("Color"); MenuItem myItem = new MenuItem("Red"); myMenu.add(myItem); myItem = new MenuItem("Green"); myMenu.add(myItem); myItem = new MenuItem("Blue"); myMenu.add(myItem); return myMenu; } private Menu getOpenMenu() { Menu myMenu = new Menu("Open"); MenuItem myItem = new MenuItem("Java"); myMenu.add(myItem); myItem = new MenuItem("HTML"); myMenu.add(myItem); myItem = new MenuItem("GIF"); myMenu.add(myItem); return myMenu; } }
If you run this example, you will see the frame window shows up with the menu bar like this:
Interesting notes about this tutorial example:
Note that there seems to be a problem with the f.setMenuBar(mb) call on macOS computers. It fails to display the menu bar.
