frame lefted unpainted after being covered with other window

[Petar Thomas]

Hi.. I hope the topic title makes sense. I have a small question.

It is an ordinary code. When I cover my frame with some other window, the circle doesn't get repainted, unless I resize a window. The JLabel "Felix" gets repainted. How can I make the circle gets repainted as well, in case when another window covers the frame, and when moved away, that place is not repainted with a circle?

Thank You for help

import javax.swing.*;
import java.awt.*;
import java.awt.geom.Ellipse2D;

public class EX extends JFrame{
    
	public EX(){
		super();
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds( 100, 100, 300, 300);
        add( new JLabel("Felix"));
        setVisible(true);
	}
	public void paint(Graphics g){
		super.paint(g);
		Graphics2D g2D = (Graphics2D)g;
		
		Shape p1 = new Ellipse2D.Float(10,10,200,200);
		//g2D.fill(p1);
		g2D.draw(p1);
	}
	
	
	
	public static void main(String[] args) {
		SwingUtilities.invokeLater(new Runnable(){
			public void run(){
				new EX();
			}
		});

	}

}

You should NOT override the paint() method of a JFrame.

Read the Swing tutorial on Custom Painting for the proper way to do this.
