doesn't draw anything

[Bobby Marvikuan]

Hi there!
Can anyone help me to understand why my code does not working please it should draw a rectangle in the JFrame but ... it does not and I am stupid because I don't see why. so here is the code.

import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;


public class Cw2 {
	public static void main(String[] args){
		Dr d = new Dr();
		d.init();
	}
}
class Dr extends JPanel{
	public void init(){
		JFrame frame = new JFrame();
		frame.add(this);
		frame.setVisible(true);
		G g = new G();
		this.add(g);
		g.draw();
		frame.setSize(600,600);
	//	frame.add(new JLabel("Hello"));
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		
	}
}
class G extends JPanel{
	public void draw(){
		Graphics g = this.getGraphics();
		g.setColor(Color.blue);
		g.fillRect(50, 50, 100, 100);
		System.out.println("I am working");
	}
}

You can use the same approach to have your custom painting instead of the image

OK thanks I see the point but if I want to add on my square smth. like JLabel will I able to do that if I am using this method with an image?

Custom painting for containers does not interfere with their ability to add children or lay them out properly.
