Images in JFrame

Hi. I need to put an image over a JFrame, I browse a lot of sites but I did not found anything useful. Someone know how to do this?
Regards.

You cannot place the image directly on the JFrame's rootpane
Try the following
JLabel imageLabel = new JLabel(new ImageIcon("test.gif"));Then add this label to your frame.

Problem with display an image on JFrame in Java 6

I'm trying to display an image on JFrame in this way:
1.) I'm creating a variable in the class:
    private Image imgSpeaker = null;2.) I'm overiting the paint method:
public void paint(Graphics g) {
        super.paint(g);
        g.drawImage(imgSpeaker, 330, 230, null);
    }3.) In the constructor I'm using this code:
   imgSpeaker = Toolkit.getDefaultToolkit().getImage("D:\\speaker.gif");
        MediaTracker trop = new MediaTracker(this);
        trop.addImage(imgSpeaker,0);
        try {
            trop.waitForID(0);    // waiting untill downloading progress will be complite
        } catch (Exception e) {
            System.err.println(e);
        }        The Image will be displayed on form, but if I catch the window and move it (for example: down as possible)
the image is not refreshed (repainted). What I'm doing wrong? I've been used this solution in Java 5 and everything
works perfectly. Any of described methods aren't depricated... Anyone can help me?

Thanks for your code, I've been tryed to apply your solution (with create a Buffered Image), but it still not working correctly. Firstly, the image isn't loading, and secondly the basic problem is not give in. Why have you been using "bg2d.draw(img, x, y, w, h, frame);" not in the paint method?
I'm use "Free Design" layout. Below I put on completly code from Netbeans.

Inserting an image to Jframe and save it , in SQL database

Hai guys,
I just wanna know about the inserting image in to a Jframe (in netBeans) it will be a grate help if you tell me the way to call a image to Jframe through a Button click and save the image in MySQl database.
Is anyone has a idea about this task, please tell me
Thanks,

Image class should work to get the data, then add it to a Canvas object, then you can save the bytes from the Image into an SQL statement through JDBC.
The implementation details will vary based on which approch and database you select.

There is no need to do custom painting to display an image.
[url http://java.sun.com/docs/books/tutorial/uiswing/components/label.html]How to Use Labels
Unless you know what you are doing, never override the paint() method of the JFrame. There is no reason to do this.
If you need to do custom painting then you override the paintComponent() method of a component that extends JComponent.

Inserting image to jFrame and save it in a sql database

Hai guys, I have a problem in inseting a image in jfame and save it in database (my sql)

Use BLOB (Binary Large Object) to save your image to a database.
As far as displaying a image on Jframe, search the forum.

How to display image in JFrame

i am comfortable with displaying an image in applets ,but i am not able to display image in JFrames
i used Image img=getImage(getDocumentBase(),"sample.jpg");its displaying an error cant find symbol getDocumentBase()

It is a method of Applet. If you have a question of what methods
are available in a given class, the very first thing you should do is check the API:
http://java.sun.com/javase/6/docs/api/
Take a look at the code in reply #2: http://forum.java.sun.com/thread.jspa?threadID=5152350

Add image to JFrame title?

Hi, everybody
Can i add a image to JFrame title by side right system menu?
Thanks for your advice

Prior to JDK 1.4 you can't without using native code.
This is because the frame's title is displayed by the native windowing system.
All you could do is use JWindow instead of JFrame and draw the decorations yourself completely. This can have other disadvantages besides the amount of work, like for example the window not showing up in the task bar on Windows systems.
Using Merlin (1.4, currently in Beta) you can tell the frame to manage the title from the Java side using JFrame.setLookAndFeelDecorated(true).
In that case the title bar is a subclass of JPanel (class name is called something like BasicTitlePaneUI, look it up yourself) and you could add anything you like to it.
Hope it helps, Stephen

How to place an image in JFrame

hello
i want to know how to place a image on JFrame
i am not using any layout..
pls help..

Hi...
To do this, u can look to tweak the paintComponent() method . All u have to do is create a JPanel subclass and override the paintComponent method to draw the image. then set it as the frame's content pane. that is because you work only on the content pane in swing. that should help.
Source for ImagePanel :
<code>
package com.rsramanujam.help;
import javax.swing.*;
import java.awt.*;
import java.awt.image.*;
public class ImagePanel extends JPanel
     Image backImage = null;
     public ImagePanel(Image backImage)
          try
               this.backImage = backImage;
          catch(Exception e)
               System.out.println("Could not get Image");
     public void paintComponent(Graphics g)
          Graphics innerG = g.create();
          if(backImage == null)
               innerG.setColor(new Color(0xffccccff));
               innerG.fill3DRect(0,0,getSize().width,getSize().height,true);
          else
               innerG.drawImage(backImage,0,0,getSize().width,getSize().height,this);
     public void setBackImage(String path)
          ImageIcon ic = new ImageIcon(path);
          this.backImage = ic.getImage();
          repaint();
</code>
U can see a working example at http://www.geocities.com/ramanujam_off/java.
There , download the app called RamHelp. It comes with a GUI that uses panels with Background Images.

Ramanujam

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.

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.*;
import javax.swing.*;
import javax.swing.border.*;
public class BackgroundBorderExample {
    public static void main(String[] args) throws IOException {
        JFrame.setDefaultLookAndFeelDecorated(true);
        JFrame f = new JFrame("BackgroundBorderExample");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JTextArea area = new JTextArea(24,80);
        area.setForeground(Color.WHITE);
        area.setOpaque(false);
        area.read(new FileReader(new File("BackgroundBorderExample.java")), null);
        final JScrollPane sp = new JScrollPane(area);
        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();
        SwingUtilities.invokeLater(r);
}

Display image in JFrame

I am looking for a way to display an image in a jframe. I want to avoid wrapping it into a container..such as a JPanel, JLabel..ect. Does anyone know a way? I seen in the API there is a Graphics function drawImage but I can not get it to work, and tried using the paintIcon function from the ImageIcon class but that doesnt work either. Any one that can help I would much appreciate it. Thanks
import javax.swing.*;
import java.awt.*;
class displayImage extends JFrame{
// user's screen width
private int screenWidth;
// user's screen height
private int screenHeight;
ImageIcon im;
Image image;
public displayImage (){
im = new ImageIcon( "<filename>" );
image = Toolkit.getDefaultToolkit().getImage("<filename>"");
screenWidth = (int)Toolkit.getDefaultToolkit().getScreenSize().getWidth();
screenHeight = (int)Toolkit.getDefaultToolkit().getScreenSize().getHeight();
resizeGUI ();
setVisible(true);
validate();
public void paint(Graphics g) {
im.paintIcon(this,g,180,0);
g.drawImage(image,0,120,this);
private void resizeGUI()
// set window size
if (screenWidth >= 1280)
setSize(1024, 768);
else if (screenWidth >= 1024)
setSize(800, 600);
else if (screenWidth >= 800)
setSize(640, 480);
// maximize window
setExtendedState(this.getExtendedState() | this.MAXIMIZED_BOTH);
public void update(Graphics g) {
paint(g);
}

1) Use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags when posting code, so the code is readable. There is also a "Preview" button as well you should be using.
2) There is no need to override paint() or update() in a Swing application. Thats old code for AWT.
I am looking for a way to display an image in a jframe. I want to avoid
wrapping it into a container..such as a JPanel, JLabel..ect.Well thats the way its done in Swing. Read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/14painting/concepts.html]Custom Painting for more information on how painting is done in Swing and you will understand why.
There actually is a solution in the forum somewhere that allows you to specify a Border, where the Border is actually a image that get painted in the background. Don't remember the posting though. Search the forum using "background image" and you might find it.

java.awt.HeadlessException: >That makes sense. It is saying that you cannot open a JFrame in an environment (the server) that does not support GUIs!
To make this so it will work on the server, it will need to be recoded so that it uses the command line only - no GUI.
What is it exactly that PinkChartFrame is generated an image of? What does it do? (OK probably 'generate a chart') But what APIs does it use (JFreeChart or such)?

Jak mozna ustawic tlo w postaci grafiki (png, jpg, ...) dla jFrame? Znalalem juz kilka sposobow ale one uzywaja jPanel, ktorego ja NIE moge uzyc ... niestety. Jesli nie ma takiej mozliwosci dla jFrame to moze tez byc dla jScrollPane, JComponent, Scene albo LayerWidget;)
Hi,
Is it possoble to use image as a background for jFrame? I know that it is possible to use jPanel and ser background image for jPanel, but in my project I cannot use it. Instead I can use jFrame, jScrollPane, Scene or LayerWidget.:)

In the future, Swing related questions should be posted in the Swing forum.
But there is already no need to post in the Swing forum because you already know the answer:
I know that it is possible to use jPanel and ser background image for jPanel,
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)", that demonstrates the incorrect behaviour.

Don't forget to use the "Code Formatting Tags", so the posted code retains its original formatting.

Resizing image in JFrame

Im trying to get the following code to resize the image that is drawn in TrackPanel, im added a resize listener but am not sure how to get the image to resize when the frame is resized.
import javax.swing.*;
import java.awt.*;
import java.awt.Dimension;
import java.awt.event.*;
import java.net.URL;
public class MyFrame {
     public static void main(String[] args)
          Frame frame = new Frame();
class Frame extends JFrame {
     private Image track;
     public Frame() {
          Class cl = this.getClass();
          Toolkit T = this.getToolkit();
track = T.getImage("C:\\track6.gif");
          MediaTracker mediaTracker = new MediaTracker(this);
mediaTracker.addImage(track, 1);
try {
mediaTracker.waitForID(1);
catch (InterruptedException ie) {
System.err.println(ie);
          addComponentListener(new ComponentAdapter() {
public void componentResized(ComponentEvent evt) {
int width = getWidth();
          int height = getHeight();
          TrackPanel track1 = new TrackPanel(track);
          getContentPane().add(track1, null);
          pack();
          setVisible(true);
class TrackPanel extends JPanel {
     private Image track;
     private int imageWidth;
     private int imageHeight;
     public TrackPanel(Image tr)
          track = tr;
          setPreferredSize(new Dimension(800, 500));
     public void paintComponent(Graphics g)
          g.drawImage(track,0,0, 800,500,this);
}

                  int height = getHeight();
          TrackPanel track1 = new TrackPanel(track);

     private int imageHeight;
     public TrackPanel(Image tr)
          track = tr;
