Sorry for a probably already solved problem, but I've searched everywhere and cannot find a solution. I've just found that no matter what, paintComponent is not called no matter where I put repaint()
I have already tried putting it in several different methods and tried to call it from different areas but no matter what, it seems to never be called.

import java.util.Scanner;
public class LevelOne extends JPanel implements KeyListener
{
int width = 0;
int height = 0;
int bx = 0;
int hx = 0;
int by = 0;
int hy = 0;
Image joe = new ImageIcon("upgrademan.png").getImage();
ImagePanel2 panel2 = new ImagePanel2(new ImageIcon("levelone.png").getImage());
JFrame frame = new JFrame ("Level One");
public LevelOne()
{
frame.getContentPane().add(panel2);
Game game1 = new Game();
frame.setSize(600, 600);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setBackground(Color.WHITE);
frame.pack();
frame.setVisible(true);
levelOne();
requestFocus();
}
public void levelOne()
{
repaint(); // this doesn't call paintComponent below?
}
public void paintComponent(Graphics g)
{
super.paintComponent(g); //draw background color
System.out.println("this enters paintComponent");
g.drawImage(joe,100,100,200,200, null); // this doesn't seem to be drawing
requestFocus();
}
public void keyPressed(KeyEvent e) // all they keyListener methods
{
}
public void keyTyped(KeyEvent e)
{
}
public void keyReleased(KeyEvent e)
{
}
}
class ImagePanel2 extends JPanel { // this entire class simply exists to call in order to set a picture as a background
Image img;
public ImagePanel2(String img) { // just sets img in method to class img variable
this(new ImageIcon(img).getImage());
}
public ImagePanel2(Image img) { // sets size of picture
this.img = img;
Dimension dims = new Dimension(600,600);
setPreferredSize(dims);
setMinimumSize(dims);
setMaximumSize(dims);
setSize(dims);
setLayout(null);
}
public void paintComponent(Graphics g) { // draws image
g.drawImage(img, 0, 0, this);
}
}
I expected the ImagePanel class to print a background, which it did, but I also expected the image called joe to print, which it did not.
