Thread: Not setting colors in JMenu submenu like it should.

It seems to do this every single solitary time so I think I can make a shorter version of it that will show what's going on.

 
import javax.swing.JMenuItem;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JPanel;
import javax.swing.JFrame;
import java.awt.Color;
 
public class BustedMenuExample 
{
 
public BustedMenuExample()
{
 
JFrame theFrame = new JFrame("Why isn't this working properly? :(  ");
 
JPanel contentPane = new JPanel();
 
theFrame.setContentPane(contentPane);
 
theFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
theFrame.setVisible(true);
 
JMenuBar jmb = new JMenuBar();
jmb.setBackground(Color.BLUE);
 
theFrame.setJMenuBar(jmb);
 
JMenu menu = new JMenu("Menu");
menu.setBackground(Color.BLUE);
menu.setForeground(Color.GREEN);
 
jmb.add(menu);
 
JMenu subMenu = new JMenu("Sub-Menu");
 
menu.add(subMenu);
 
subMenu.setBackground(Color.BLUE);
subMenu.setForeground(Color.GREEN);
 
JMenuItem menuItem = new JMenuItem("Menu Item");
 
subMenu.add(menuItem);
 
menuItem.setBackground(Color.BLUE);
menuItem.setForeground(Color.GREEN);
 
JMenuItem menuItem2 = new JMenuItem("Menu Item 2");
 
subMenu.add(menuItem2);
 
menuItem2.setBackground(Color.BLUE);
 
menuItem2.setForeground(Color.GREEN);
 
 
 
 
 
 
 
}
 
public static void main(String[] args)
{
new BustedMenuExample();
 
 
 
}
 
}

I'm thinking that all the backgrounds and stuff will be fine except that subMenu will still have a cyan background and black foreground. Why is that happening?

I think I figured it out. You use setOpaque(true); Yes, that worked. That was just a hunch though.

What does opaque mean anyway? I thought it meant see-through or something.

Another thing I was slightly wondering is how do you set the selectionColor? I mean, when it's selected, it appears to be a dark gray by default. How would you make it, say, a dark red instead or something?

Is this what you are talking about: http://www.javaprogrammingforums.com...ouse-over.html
