JPanel not visible? Am I stupid!?

Hi, I got this simple code:

Code:

---

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;


public class paint extends JFrame{
       
        JPanel panel = new JPanel();
        public void paint(Graphics g){
                g.drawRoundRect(20, 20, 50, 50, 10, 10);
        }
       
        public static void main (String[] args){
                paint p = new paint();
        }
       
        public paint(){
                getContentPane().setLayout(null);
                setSize(300, 200);
                setBackground(Color.WHITE);
                setForeground(Color.BLACK);
                panel.setBackground(Color.RED);
                panel.setSize(300,200);
                panel.setVisible(true);
                add(panel);
                setVisible(true);
        }
}

Now why the hell can't i see the JPanel?! I have dont almost the exact same thing in another program, and it works perfectly =( I can see the drawn "roundrect", but there is no background. Also, why does setBackground, and setForeground never work on JFrame??

TY!

try these bounds:

g.drawRoundRect(20, 50, 50, 50, 10, 10);

Please read the Swing tutorials first. You are doing so many things wrong I have to wonder if you haven't done this most basic step yet.

For example, you are

• Drawing right on the JFrame itself instead of in a JPanel's paintComponent method
• Covering up you're what you're drawing by putting a component on top of it
• Using wrong Java naming conventions
• trying to set component's sizes directly rather than preferred size and calling pack() on the JFrame
• setting background and foreground colors of a JFrame (this does nothing at all useful)
• ...

Also please search this forum for sample code that shows drawing in Swing applications. There are many such examples around here, I know, because I've written a few.
