Background image on a JPanel

Hi
I wonder if there's possible to set a background image, not just a colour, on a JPanel, and if so, how do I do it?

How will I put a background Image in a JPanel?

Can you help me on how will I put a background image in a JPanel?
And also in a JDeskTopPane?

Hint:
Search the forum using two keywords in your subject. This question had been asked many times.

Background Image in JPanel.

Hi, I am trying to set a background image to my JPanel. So far everything ok. However When I add labels to this panel as well the image is displayed but the label is not! I tried to make a search on google, and I found some links pointing to this forum, however none of them (which) I have seen show how to display a backgroun image and a label on top.
What I tried to to is override the paint method of the JPanel. Here I did the following code:
public void paint(Graphics g){
   Image i = this.myImage // Were myImage is of type Image with a loaded image in.
   g = super.getGraphics();
   g.drawImage(i, 0, 0, this);
   super.paint(g);
}However this code brings the label and the image always blinking. I can imagine the reason for this is that the paint method is called all the time, and thus the image and the label are being painted all the time and so there is the blinking effect.
Does anyone know how I can set a background image to my JPanel in an efficient way?

No Gosling? I just retried it and it works for me.
Maybe you're having trouble with the image URL.
Try it with a local image.

Background image for JPanel using UI Properties

Is there any way to add background image for JPanel using UI Properties,
code is
if (property.equals("img")) {
System.out.println("call image file in css"+comp);
//set the background color for Jpanel

Help getting a background image to show through a JScrollpane

I have a GUI program which has a front menu with buttons on it. I have managed to get the background image displaying as I want it there by overriding the paintComponent method.
My problem occurs when after clicking the "passport" button, a JScrollPane is added to the JPanel.
I am having problems making the JScrollPane non-opaque( so i can see the image behind it).
I have tried setting both scrollPane.setOpaque(false) and scrollPane.getViewport().setOpaque(false) and neither of these have worked.
If anyone has managed to get a background image working with a JScrollpane then some help would be greatly appreciated.

Swing related questions should be posted in the Swing forum.
You seem to be doing things backwards.
Add a background image to a JPanel. (Examples can be found by searching the Swing forum using "background image" as the keywords.
Then add your labels to the same panel and then add the panel to the scrollPane.

Can anyone suggest me a simple way to add a background image to JFrame ?

I want to add a background image to JFrame in a simple way rather than overiding the paint method or paintComponent method. Just like adding an image to JButton or JLabel using two or three lines of code. Is it possible ? r there any methods for this purpose ? if so pls give the code.

JFrame as such does not provide an option to set a background image.
Extending JPanel, over-riding its paintComponent() and setting it as the contentPane of JFrame is one way of doing it. Though you have to do the overriding, it is not very complex though.

Trouble with background image in JPanel

I'm trying to get an image to display as a background image, and then put JLabels with other content on top of that background image. I've tried several things but can't figure out how to do it. Everytime I try, I get the images to display but the content is displayed side by side because of the layout manager.
I've tried this but the image is displayed very tiny and still is not displayed in the background.
   //*   Draw background images for panels            *
       public class BackgroundPanel extends JPanel
      // the image you want displayed in the background
         private Image background;
      // A constructor to build and initialise your panel.
      // @param resourceName
          public BackgroundPanel(String resourceName)
            background = new ImageIcon( getClass().getClassLoader().getResource( resourceName )).getImage();
            setOpaque(false);
      // @see java.awt.Container#paint(java.awt.Graphics)
          public void paint(Graphics g)
            g.drawImage(background, 0, 0, 200, 480, this);
         // draw the rest of the panel and it's children
              super.paint(g);
      }

To add a background to a Swing component, do not overload the public void paint(Graphics g); methods, but the public void paintComponent(Graphics g); instead, otherwise, the background will always overlap the Swing components added.
Here is a goog working code:
public void paintComponent(Graphics g) {
     super.paintComponent(g);
     g.drawImage(myStaticBackground, this.getWidth() - 256, this.getHeight() - 256, this);
}In this example, I draw a static Image sized 256�256 at the bottom right corner.

Problem with Background image and JFrame

Hi there!
I've the following problem:
I created a JFrame with an integrated JPanel. In this JFrame I display a background image. Therefore I've used my own contentPane:
public class MContentPane extends JComponent{
private Image backgroundImage = null;
public MContentPane() {
super();
* Returns the background image
* @return Background image
public Image getBackgroundImage() {
return backgroundImage;
* Sets the background image
* @param backgroundImage Background image
public void setBackgroundImage(Image backgroundImage) {
this.backgroundImage = backgroundImage;
* Overrides the painting to display a background image
protected void paintComponent(Graphics g) {
if (isOpaque()) {
g.setColor(getBackground());
g.fillRect(0, 0, getWidth(), getHeight());
if (backgroundImage != null) {
g.drawImage(backgroundImage,0,0,this);
super.paintComponent(g);
Now the background image displays correct. But as soon as I click on some combobox that is placed within the integrated JPanel I see fractals of the opened combobox on the background. When I minimize
the Frame they disappear. Sometimes though I get also some fractals when resizing the JFrame.
It seems there is some problem with the redrawing of the background e.g. it doesn't get redrawn as often as it should be!?
Could anyone give me some hint, on how to achieve a clear background after clicking some combobox?
Thx in advance

I still prefer using a border to draw a background image:
import java.awt.*;
import java.awt.image.*;
import javax.swing.border.*;
public class CentredBackgroundBorder implements Border {
    private final BufferedImage image;
    public CentredBackgroundBorder(BufferedImage image) {
        this.image = image;
    public void paintBorder(Component c, Graphics g, int x, int y, int width, int height) {
        int x0 = x + (width-image.getWidth())/2;
        int y0 = y + (height-image.getHeight())/2;
        g. drawImage(image, x0, y0, null);
    public Insets getBorderInsets(Component c) {
        return new Insets(0,0,0,0);
    public boolean isBorderOpaque() {
        return true;
}And here is a demo where I load the background image asynchronously, so that I can launch the GUI before the image is done loading. Warning: you may find the image disturbing...
import java.awt.*;
import java.io.*;
import java.net.URL;
import javax.imageio.*;

        area.setForeground(Color.WHITE);
        area.setOpaque(false);

        sp.setBackground(Color.BLACK);
        sp.getViewport().setOpaque(false);
        f.getContentPane().add(sp);
        f.setSize(600,400);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
        String url = "http://today.java.net/jag/bio/JagHeadshot.jpg";
        final Border bkgrnd = new CentredBackgroundBorder(ImageIO.read(new URL(url)));
        Runnable r = new Runnable() {
            public void run() {
                sp.setViewportBorder(bkgrnd);
                sp.repaint();

Animated gif layered above background image

I have a static background image which is displayed in a JPanel. I need to display animated gifs at certain positions on the base image. For every new frame of the animation, the paint method is called whcih attempts to load the entire base image + all the new animated images which is extremely slow!. It also means the animated gif keeps on getting loaded, and seldom gets beyond the first frame.
Im sure many people have had to do something like this. Is the solution to draw the gifs on the glasspane (or use layered panes), and to have a seperate paint method? or is their a simple approach like setting a special clip area.

thanks for the help...
The size of the background image is approx 400*400 pixels (gif or jpg), and the icons are 25*25, and have between 1 and 6 frames.
Here comes the code... I havent finished with the mediatracker stuff, but youll get the idea Im sure.
public void paint(Graphics g) {
 MediaTracker tracker = new MediaTracker(this);
 tracker.addImage(image,0);
 try {tracker.waitForID(0);}
 catch (InterruptedException e){}
 g.drawImage(image, 0, 0, this); //draw background image (approx 400*400 pixels)
 int ICON_ID = -1;
 Image img;
 //draw all the icons...
 //all icons have between 1 and 6 frames. 25*25 pixels.
 for (int i = 0; i < icon_IDs.size(); i++) {
 try {
 ICON_ID = new Integer(icon_IDs.elementAt(i).toString()).intValue();
 Point p = dm.getIconPosition(ICON_ID);
 if (isAlarm(ICON_ID)) { //ITS AN ALARM - use animated gif
 img = getAlarmImage(ICON_ID);
 else //NORMAL ICON - no animation
 img = DataDefinition.getImageIcon(dm.getIconType(ICON_ID)).getImage();
 tracker.addImage(img,0);
 try {tracker.waitForID(0);}
 catch (InterruptedException e){}
 int width = DataDefinition.getSize(dm.getIconType(ICON_ID)).width;
 int height = DataDefinition.getSize(dm.getIconType(ICON_ID)).height;
 g.setClip(p.x, p.y, p.x+width, p.y+height);
 g.drawImage(img, p.x, p.y, p.x+width, p.y+height, 0,0,img.getWidth(this),img.getHeight(this),this);
 catch (SQLException sqle) {
 System.out.println("Could not find position of icon : " + ICON_ID);

Problem in setting background Image to TabedPane.

Hi Pals,
I created a JFrame which consist of some components. The structure of the added components are given below.
1) I added a JPanel (MainPanel) with background image in a JFrame.
2) I added a JTabbedPane with 7 tabs in the previous JPanel (MainPanel).
3) Each tabs in the JTabbedPane having JPanel with Background Image.
This is my Frame Structure. but i haven't problem to run in JDK1.6,1.5. It is working perfect. But when am run in lower version like 1.3 or 1.4. The design is looking bad. The JTabbedPane overlap the (MainPanel). The background image of the (MainPanel) was hided. I set setOpaque(false) for the JTabbedPane. But it also not working. How can i solve this problem.

Mohan

How to load a background Image on a JDialog object

Hi All, Actually i am new to java programing and i am stuck in this problem. I am developing a java application which is dialog based (using JDialog objects) and i want to load a background image on my dialog. I hope this could be done and i really appreciate your help because i must deliver this project and this is a user interface requirement.

Try something along the lines of this: Create a new class called BackgroundImagePanel and have it extend JPanel.
Have an attribute in the class for your image, and a method to set it.
Override isOpaque() to return true.
Override the paintComponenet method as such:
public void paintComponent (Graphics g) {
super.paintComponent(g);
if( image == null ) return;
Icon icon = new ImageIcon(image);
icon.paintIcon(this, g, x, y);
Add this panel to your JDialog and then add other component to this panel.
You might have to tweak this a bit, but it should get you close...

Problem placing buttons on top of a background image

My knowledge of Java isn't the greatest and I am currently having problems placing buttons on top of a background image within a JApplet (this is also my first encounter with Applets).
I'm using a Card Layout in order to display a series of different screens upon request.
The first card is used as a Splash Screen which is displayed for 5 seconds before changing to the Main Menu card.

1) When posting here, please use fewer comments. The comments that you have don't help folks who know Java read and understand your program and in fact hinder this ability, which makes it less likely that someone will in fact read your code and help you -- something you definitely don't want to have happen! Instead, strive to make your variable and method names as logical and self-commenting as possible, and use comments judiciously and a bit more sparingly.
2) Try to use more methods and even classes to "divide and conquer".
3) To create a panel with a background image that can hold buttons and such, you should create an object that overrides JPanel and has a paintComponent override method within it that draws your image using the graphics object's drawImage(...) method
For instance:
an image jpanel:
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;
import javax.imageio.ImageIO;
import javax.swing.JButton;

How to get Internal frames as well as a background image in a JFrame?

Hi All,
Here's my problem. I have a JFrame with a background image that I got by overridding the paintComponent() method of a JPanel and setting as the contentPane of a JFrame. Works great.
Now what I want is to use internal frames with this Frame a la JInternalFrame classes. But you need to create a JDesktopPane object and set this as the contentPane of the JFrame to get internal frames to work, right? Is there a way for me to have my cake and eat it so I get both internal frames and a background image? Thanks!

Hmmm,
so simple, why didn't I think of that? Damn Mondays!
thanks very much!
