Canvas + JMenu

[Dan Grieve]

Hey all, I've spent enough time creating programs etc using just buttons and menus, and thought I'd spread my wings into the 2d graphics land. Thought for my first go I'd set up a simple "Paint" program, and ran into a little issue with the drawing canvas and JMenu's.

I've got 2 classes (which are at the bottom of the post), one to handle the frame, menus, events and whatnot, and the other class just simply extends Canvas and draws an oval. The problem is, when I click on a menu, the menu appears behind the canvas, what can I do to bring either the menu to the front, or send the canvas to the back.

Paint.class
----------------------------------------

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
 
class Paint extends JFrame {
 
protected static JMenuBar menu;
protected static JMenu file;
protected static JMenu insert;
protected static JMenuItem oval;
protected static JMenuItem rectangle;
 
public Paint() {

menu = new JMenuBar();

setJMenuBar(menu);

file = new JMenu("File");
insert = new JMenu("Insert");

oval = new JMenuItem("Oval");
rectangle = new JMenuItem("Rectangle");

insert.add(oval);
insert.add(rectangle);

menu.add(file);
menu.add(insert);

setLayout(new BorderLayout());

add(new Drawing(), BorderLayout.CENTER);

}

public static void main(String[] args) {

Paint frame = new Paint();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(600,500);
frame.setVisible(true);
frame.setTitle("Peaynt");

}

}

Drawing.class
----------------------------------------

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
 
class Drawing extends Canvas {
 
public void paint(Graphics g) {
 
g.setColor(Color.red);
g.fillOval(0,0,200,200);

}

}

If you could point me in the right direction I'd appreciate it, cheers.

then change Canvas to JPanel, and use its paintComponent(..) for your graphics
