here is some code for a glasspane that I have.
For some reason, it never hits the paintComponent.

My program does:

public class GlassPane extends JPanel {
    
    /** Creates a new instance of glassPane */
    public GlassPane() {
        
    }
    
    public void cashierAction(JPanel panel, int initialX, int initialY) {
        frame = (JFrame)SwingUtilities.getAncestorOfClass(JFrame.class, panel);
        glass = (JPanel) frame.getGlassPane();
        //glass.setLayout(null);
        
        xPos = initialX;
        yPos = initialY;
        
        glass.setVisible(true);
        
        cashierAnimation = true;
        
        repaint();
        
    }
    
    public void paintComponent(Graphics g) {
        Graphics2D g2d = (Graphics2D)g;
        super.paintComponent(g);

        if(cashierAnimation) {
            g2d.drawImage(this.dollarSign, xPos, yPos, 10, 10, null);
        }
    }
    
    
    private JFrame frame;
    private JPanel glass;
    private int xPos;
    private int yPos;
    private boolean cashierAnimation = false;
    private ImageIcon dollarImg = new ImageIcon("Data/Icons/dollar.gif");
    private Image dollarSign = dollarImg.getImage();
    
}

Any ideas why it is not running the paintComponent?
I am pretty new to glass panes, I have gotten them to work with buttons, and other items, but painting on them is driving me crazy.
