Set Background image to JScrollPaneNeed Help!!

Hi there;

No; i want to set a separete backgroung image for this label in the JScrollPane. This label is my main component, other than that

i have this image

Image watermarkImg = Toolkit.getDefaultToolkit().getImage("C:\temp\watermark.jpg");

I want to make this image as the background image to this JScrollPane(or to this label) and should be shown as a watermark(background image) behind this label. (Some thing similar to behing text in microsoft work).

My JScrollPane constructor is as follows:

JLabel imageLabel;

BufferedImage pageImage = renderer.getLastRenderedPage();

imageLabel.setIcon(new ImageIcon(tempBufferedImage));

JScrollPane jsp;

jsp = new JScrollPane(imageLabel);

thanks

Just read your reply... You don't need the JScrollPane to do what you want - but I suspect you can modify the code I posted to achieve what you want... Just create a LayeredPane, add the imageLabel, and then add the Label on top of that (set the opacity as you see fit)...

You can then place the LayeredPane where-ever you like...

Hope that helps...

I included a complete code listing of a functional example. The main problem with wha tI shared earlier was that I did it quickly in Groovy, where everything is an object. When I called layeredPane.add(xxx, 4) - the number 4 was an object - whereas in Java it is not - this called the wrong function so that the label would not appear... ok - here is the code... run this with your own image and then modify it to do what you need...

import java.awt.Dimension;

import java.awt.image.BufferedImage;

import java.io.File;

import javax.imageio.ImageIO;

import javax.swing.ImageIcon;

import javax.swing.JFrame;

import javax.swing.JLabel;

import javax.swing.JLayeredPane;

import javax.swing.JScrollPane;

public class BackgroundImageExample {

public static void main(String[] args) {

try {

//Load Image

String filename = "/home/dlpinto/Desktop/Screenshot.png";

BufferedImage image = ImageIO.read(new File(filename));

//Create Image Label

JLabel label = new JLabel(new ImageIcon(image));

label.setBounds(0, 0, image.getWidth(), image.getHeight());

//Create Layered Pane

JLayeredPane layeredPane = new JLayeredPane();

layeredPane.setLayout(null);

layeredPane.setPreferredSize(new Dimension(image.getWidth(), image.getHeight()));

//Create Desired Components

JLabel messageLabel = new JLabel("Hello World");

messageLabel.setOpaque(true);

messageLabel.setBounds(50, 50, 100, 100);

//Populate Layered Pane

layeredPane.add(label, new Integer(JLayeredPane.DEFAULT_LAYER-1));

layeredPane.add(messageLabel, JLayeredPane.DEFAULT_LAYER);

//Create ScrollPane

JScrollPane sp = new JScrollPane(layeredPane);

//Create & Display Frame

JFrame frame = new JFrame();

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(800, 600);

frame.add(sp);

frame.setVisible(true);

System.out.println(layeredPane.getLayer(messageLabel));

System.out.println(layeredPane.getLayer(label));

} catch (Exception e) {

e.printStackTrace();

}

}

}

Hi equilibric and DrLaszloJamf

Thanks alot again

Yes tried out both examples but the problem in my case is The foreground labe which i'm using is not just a label where u can separate text.

In equilibric; u have used a label

JLabel messageLabel = new JLabel("Hello World");

in DrLaszloJamf have use a area; there also u can separete text

JTextArea area = new JTextArea();

area.read(new FileReader("CentredBackgroundBorder.java"), null);

in my case:

private JLabel imageLabel = new JLabel();

BufferedImage pageImage = renderer.getLastRenderedPage();

imageLabel.setIcon(new ImageIcon(tempBufferedImage));

I have set a buffered image to label's icon, so it also acting as a image. So when i set my imageLabel in front of my backgroung image, it doesn't visible the backimage because of the foreground image.

thanx

Regards

madumm

Can u give some solution to my prob
