Adding a background image to my JTextField

How do I add a background image to my JTextField?

Make sure the opaqueness property of your JTextField component is false. You can then override the paintComponent method that draws the background image and calls super.paintComponent. Here’s an example:

import javax.swing.*;
import java.awt.*;
 
public class Main {
   public static void main(String args[]) {
      JFrame frame = new JFrame("JTextField Background Demonstration");
      final ImageIcon imageIcon = new ImageIcon("bluebg.jpg");
 
      JTextField textField = new JTextField() {
         Image image = imageIcon.getImage();
         { 
            setOpaque(false);
         }
         public void paintComponent (Graphics g) {
            g.drawImage(image, 0, 0, this);
            setForeground(Color.yellow);
            super.paintComponent(g);
         }
      };
      textField.setFont(new Font("Helvetica", Font.BOLD, 16));
 
      frame.getContentPane().add(BorderLayout.CENTER, textField);
      frame.setDefaultCloseOperation(3);
      frame.setSize(200, 50);
      frame.setVisible(true);
      frame.setResizable(false);
   }
}
