JOptionPane background Image

Question

How to set background image of JOptionPane? I want to show another image in the background of JOptionPane.

Answer 1

You can extend the JOptionPane class and override the drawing method.

Edit: Depending on the resolution and image quality, you can stretch it using AffineTransform during WindowResize events without significant distortion. This will allow you to handle the JOptionPane and image size inconsistencies mentioned below.

class ImageBackgroundPane extends JOptionPane { private BufferedImage img; public ImageBackgroundPane (BufferedImage image) { this.img = image; } @Override public void paint(Graphics g) { //Pick one of the two painting methods below. //Option 1: //Define the bounding region to paint based on image size. //Be careful, if the image is smaller than the JOptionPane size you //will see a solid white background where the image does not reach. g.drawImage(img, 0, 0, img.getWidth(), img.getHeight()); //Option 2: //If the image can be guaranteed to be larger than the JOptionPane size Dimension curSize = this.getSize(); g.drawImage(img, 0, 0, curSize.width, curSize.height, null); //Make sure to paint all the other properties of Swing components. super.paint(g); } }
