[JAVA] Use the Mac menu bar with Processing 3 apps

The menu bar at the top of your Mac desktop Let's use it in an application created with Processing3.

Caution

--Operating environment: processing3.3 --The menu bar at the top of the desktop can only be used after exporting as an app

Contents

To create a menu bar, use JMenuBar in Java's Swing.

sample.pde

import java.awt.*;
import javax.swing.*;

JLayeredPane pane = new JLayeredPane();
JMenuBar  menubar = new JMenuBar();

void setup() {
  System.setProperty("apple.laf.useScreenMenuBar", "true");
  
  Canvas canvas = (Canvas) surface.getNative();
  pane = (JLayeredPane) canvas.getParent().getParent();

  JMenu     menu = new JMenu("menu");
  JMenuItem item = new JMenuItem("item");
  menu.add(item);
  menubar.add(menu);
  pane.add(menubar);
}

System.setProperty("apple.laf.useScreenMenuBar", "true"); This will allow you to use the Mac menu bar.

If it looks like this, it's a success.
