paintComponent removing text value of button

Question

I am setting background image for JButton or say JTableHeader. When I do paintComponent on the same, it's removing text value set for that component.

Any idea where I am going wrong?

JButton btn = new JButton(){
    @Override
    public void paintComponent(Graphics g){
        Dimension size = this.getSize();
        g.drawImage(Toolkit.getDefaultToolkit().getImage("C:\\User\\Downloads\\MainMenu.jpg"), 0, 0, size.width, size.height, this);
    }
};
btn.setText("TEST WITH ME");
btn.setOpaque(true);

Answer 1

I may have not specified that much correct what I really wanted. But I figured out answer for that.

@Override
public void paintComponent(Graphics g){
    Dimension size = this.getSize();
    g.drawImage(Toolkit.getDefaultToolkit().getImage("C:\\User\\Downloads\\MainMenu.jpg"), 0, 0, size.width, size.height, this);
    FontMetrics fm = g.getFontMetrics();
    int x = (getWidth() - fm.stringWidth("String Value To Set")) / 2;
    int y = ( (getHeight() - fm.getHeight() ) / 2) + fm.getAscent() ;
    g.drawString(String Value To Set, x, y);
}
