Thread: JButton with 2D Graphics help

Hello, I'm having some issues getting a JButton to show on a frame where I have created some 2D graphics objects. Objective is to have the button change the smile displayed to a frown when the button is pressed. Any help would be much appreciated.

I have tried adding the button both in the constructor and in the paint method. I have also tried repositioning it in both methods.

import javax.swing.*;
import java.awt.*;
import java.awt.geom.*;
import java.awt.event.*;
 
public class JSmileyFace2 extends JFrame implements ActionListener
{
 
    private JButton mouth = new JButton("Smile");
 
    public JSmileyFace2()
    {
        super("Smile");
        setVisible(true);
        setSize(300,320);
        setBackground(Color.WHITE);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
        add(mouth);
        mouth.addActionListener(this);
    }
 
    public void paint(Graphics gr)
    {
        super.paint(gr);
 
        Graphics2D gr2d = (Graphics2D)gr;
        BasicStroke brush = new BasicStroke(5.0f, BasicStroke.CAP_ROUND,
                BasicStroke.JOIN_ROUND);
        gr2d.setStroke(brush);
 
        //Draws outer smiley
        gr2d.setPaint(Color.YELLOW);
        gr2d.fill(new Ellipse2D.Float(30F, 80F, 200F, 200F));
        gr2d.setPaint(Color.BLACK);
        gr2d.draw(new Ellipse2D.Float(30F, 80F, 200F, 200F));
 
        //draws eyes
        gr2d.fill(new Ellipse2D.Float(90F, 110F, 20F, 60F));
        gr2d.fill(new Ellipse2D.Float(150F, 110F, 20F, 60F));
 
        //draws mouth based on button text
        if(mouth.getText().equals("Smile")) //draws smile
            gr2d.draw(new Arc2D.Float(70F, 140F, 120F, 120F, 180F, 180F, Arc2D.OPEN));
        else //draws frown
            gr2d.draw(new Arc2D.Float(70F, 180F, 120F, 120F, 180F, -180F, Arc2D.OPEN));
        mouth.setLocation(20,20);
    }
 
    public void actionPerformed(ActionEvent e)
    {
        if(mouth.getText().equals("Smile"))
            mouth.setText("Frown");
        else
            mouth.setText("Smile");
        repaint();
    }
 
    public static void main(String[] args)
    {
        JSmileyFace2 frame = new JSmileyFace2();
    }
