JTextPane fixed background image

Question

Dude, on package foo.bar I have got a JTextPane class(MyJTextPane), and an image back.png.
Now I would do something in CSS with my Text pane, I like to use the embedded back.png file as fixed-scroll, both horizontal and vertical center position.
There is no any surprise about the css which would be like this.

body { 
  background: url('back.png') no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

My question, is it possible at all to apply this property for JTextPane too? if yes, so how would I point out the embedded image resource here?
If no, is there another solution then?
Thanks in advance.

Do custom painting on the background of the JViewport:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;

public class ViewportBackground
{
    private static void createAndShowUI()
    {
        JTextArea textArea = new JTextArea(5, 30);
        textArea.setOpaque(false);

        JViewport viewport = new JViewport()
        {
            @Override
            protected void paintComponent(Graphics g)
            {
                super.paintComponent(g);
                int w = this.getWidth();
                int h = this.getHeight();
                g.setColor(new Color(0, 0, 255, 50));
                g.fillRect(0, 0, w/2, h/2);
                g.setColor(new Color(255, 0, 0, 50));
                g.fillRect(w/2, 0, w, h/2);
                g.setColor(new Color(0, 255, 0, 50));
                g.fillRect(0, h/2, w, h/2);
            }
        };

        JScrollPane scrollPane = new JScrollPane();
        scrollPane.setViewport(viewport);
        scrollPane.setViewportView( textArea );

        JFrame frame = new JFrame("SSCCE");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add( scrollPane );
        frame.setLocationByPlatform( true );
        frame.pack();
        frame.setVisible( true );
    }

    public static void main(String[] args)
    {
        EventQueue.invokeLater(new Runnable()
        {
            public void run()
            {
                createAndShowUI();
            }
        });
    }
}

This example just paints a patterned background, buy you can easily use the Graphics.drawImage(...) method to paint an image for the background.

Very nice solution bro, so you mean this is the only way to have something like this? — , May 19 '14 at 16:34
+1 but I'd suggest to [setScrollMode](http://stackoverflow.com/questions/8197261/jtable-how-to-change-background-color) — mKorbel, May 19 '14 at 18:49
