Put an Image to a JPanel

Is there an easy way to put a Image to a JPanel (or as a background for the JPanel). Or is there some kind of JImagePanel class that I can use.

Hi,
put JLabel into JPanel and an image put into JLabel. And next time try to search the forum first.
L.P.

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

Putting an Image in JPanel

I am trying to put an image in JPanel. Using something other than ImageIcon. When I run the program only a white screen appears.

     /*private void chooseBufferSrategy()
     private void setFullScreen()
          GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().setFullScreenWindow(this);
}

super.paintComponent(g);should be the first line in paintComponent()
also, you don't really need the keyBindings to quit,
just set the default close to exit and Alt-F4 will close/quit

Putting an image into a JFrame or a JPanel

Hello everybody,
I'd like to know how to put an image (a real one, not a small icon we can't see it!) into a JFrame, or a JPanel, or included into a miscellanea element (label, textfield or somethiong else).
Thanks,
Regards
Cedric

Hi Cedric,
If the image format is Jpg or gif, then the best way to insert the image
into the Frame or panel is to use JLabel. You can pass the argument to the file as parameter to JLabel construction.
For other formats, you have the option of using drawimage in paint function of applets.
Hope this helps.
Best Regards,
Chandru

Putting an Image in my CoordinateArea

Hey,
I would like to be able to place an image within my CoordinateArea, and I also want this image to be able to respond to being clicked on when the mouse is clicked between certain co-ordinates. Here is my code so far...
import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseEvent;
import javax.swing.event.MouseInputListener;
public class tourWelby extends JFrame {
JLabel label = new JLabel();
JPanel panel = new JPanel();
Point clickPoint = new Point();
Point cursorPoint = new Point();
private static void createAndShowGUI() {
JFrame.setDefaultLookAndFeelDecorated(true);
 JFrame frame = new JFrame("TourWelby");
 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 tourWelby controller = new tourWelby();
 controller.buildUI(frame.getContentPane());
 //Create and set up the content pane.
 frame.getContentPane().setBackground(Color.BLACK);
 // Create the menu bar
 JMenuBar menu = new JMenuBar();
 menu.setBackground(Color.BLACK);
 //Build the menus.
 JMenu file = new JMenu("File");
 file.setBackground(Color.BLACK);
 file.setForeground(Color.WHITE);
 JMenu test = new JMenu("Test");
 test.setBackground(Color.BLACK);
 test.setForeground(Color.WHITE);
 // Install the menu bar in the frame
 frame.setJMenuBar(menu);
 menu.add(file);
 menu.add(test);
 //Display the window.
 frame.pack();
 frame.setVisible(true);
 frame.setResizable(false);
 frame.setSize(800,700);
 private void buildUI(Container container) {
container.setLayout(new BoxLayout(container,
BoxLayout.PAGE_AXIS));
CoordinateArea theArea = new CoordinateArea(this);
container.add(theArea);
label = new JLabel();
 label.setBackground(Color.BLACK);
 label.setForeground(Color.WHITE);
resetLabel();
container.add(label);
public void updateCursorLocation(int x, int y) {
if (x < 0 || y < 0) {
cursorPoint = null;
updateLabel();
return;
if (cursorPoint == null) {
cursorPoint = new Point();
cursorPoint.x = x;
cursorPoint.y = y;
updateLabel();
public void updateClickPoint(Point p) {
clickPoint = p;
updateLabel();
public void resetLabel() {
cursorPoint = null;
updateLabel();
protected void updateLabel() {
String text = "The cursor is at ";
 if (cursorPoint != null) {
text += "("
+ cursorPoint.x + ", " + cursorPoint.y + ") ";
label.setText(text);
 public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
public static class CoordinateArea extends JComponent implements MouseInputListener {
Point point = null;
tourWelby controller;
Dimension preferredSize = new Dimension(800,700);
public CoordinateArea(tourWelby controller) {
this.controller = controller;
 setBorder(BorderFactory.createMatteBorder(3,3,3,3, Color.RED));
addMouseListener(this);
addMouseMotionListener(this);
public Dimension getPreferredSize() {
return preferredSize;
//Methods required by the MouseInputListener interface.
public void mouseClicked(MouseEvent e) {
int x = e.getX();
int y = e.getY();
if (point == null) {
point = new Point(x, y);
} else {
point.x = x;
point.y = y;
controller.updateClickPoint(point);
repaint();
public void mouseMoved(MouseEvent e) {
controller.updateCursorLocation(e.getX(), e.getY());
public void mouseExited(MouseEvent e) {
controller.resetLabel();
public void mouseReleased(MouseEvent e) { }
public void mouseEntered(MouseEvent e) { }
public void mousePressed(MouseEvent e) { }
public void mouseDragged(MouseEvent e) { }
How do I go about putting an image in the CoordinateArea and making it clickable? Do I need to use an ImageIcon?
Thanks in advance.

Hi again everyone. I've gone and rethought my code and started again from scratch. Here is what I have come up with..
import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
import java.awt.event.*;
public class tourWelby extends JFrame implements MouseListener {
public void mouseReleased(MouseEvent e) { }
public void mouseEntered(MouseEvent e) { }
public void mousePressed(MouseEvent e) { }
public void mouseDragged(MouseEvent e) { }
public void mouseExited(MouseEvent e) { }
public void mouseClicked(MouseEvent e) { }
public static void main (String args[]) {
 new tourWelby();
 public tourWelby() {
 super("Test");
 Container content = getContentPane();
 Point clickPoint = new Point();
 Point cursorPoint = new Point();
 JLabel label = new JLabel();
 label.setText("Test");
 label.setBackground(Color.WHITE);
 label.setForeground(Color.WHITE);
 JPanel theArea = new JPanel();
 theArea.setPreferredSize(new Dimension(800, 600));
 theArea.setBackground(Color.BLACK);
 theArea.add(label);
 theArea.addMouseListener(this);
 addMouseListener(this);
 content.add(theArea);
 pack();
 setVisible(true);
 setResizable(false);
}Basiclly now, I think I need to add the mouseListener to the JPanel. However I'm not sure where I need to put the "public void updateCursorLocation" code and such that I had before (before, I used some samples of code from another program, and I wasn't entirely sure how it worked). If someone could help me (again!) with getting the MouseListener to change the label on the JPanel, to reflect where the cursor is (as in my previous code) I would again, be most appreciative. Thanks.

How can I put an image/s in Java Application?

Hi to all.
How can I put an image/s in Java Application?
I can put some images in Java applet but when i try to put it in Java application there was an error.

hey u can easily do it with JLabels...i found a Code Snippet for u
public class MyPanel extends JPanel
{private JLabel imageLabel; public MyPanel() { Image image = Toolkit.getDefaultToolkit().getImage("myimage.gif"); // Could be jpg or png too imageLabel = new JLabel(new ImageIcon(image)); this.add(imageLabel); }}
hope it helps

Putting an image into a JApplet

Okay so I've made a logo in Fireworks, saved as a jpg, and now I'm trying to put it on to my JApplet.
I've tried...
ImageIcon logo = new ImageIcon("C:\folder1\folder2\image.jpg");
mainNorth.add(logo);
but it says illegal escape character compiler error...any ideas? :s

Aurora88 wrote:
it still says illegal escape character...:sLet's see:
1) the complete error message (yes, the whole thing, and please put it between code tags)
2) an SSCCE -- a small program that compiles and demonstrates your problem. This program will just create a JApplet and try to place an image in a JPanel of the JApplet, it should be enough code to demonstrate your problem and nothing else. For more information, have a look at this:
http://homepage1.nifty.com/algafield/sscce.html
Remember, the code must be compilable and runnable for many of us to be able to understand it fully.
Also, when posting your code, please use code tags so that your code will retain its formatting and be readable. To do this, either use the "code" button at the top of the forum Message editor or place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:

Putting an image in a JFrame

I'm trying to paint an image onto a JFrame. Im making a monopoly game and need to paint the board, and repaint it after every turn. I dont know how to put an image onto a JFrame and was wondering if anyone could give me a basic algorithm or code example of how to do this. Thanks.

Here is the basic algorithm to paint to a JFrame:
Don't do it!
Set the preferred size of a JPanel and add the JPanel to the JFrame. Paint to the JPanel by extending the paintComponent method. When you're ready to display, then remember to pack the JFrame and setVisible appropriately.
You can read about doing this in the Java Tutorial.
public void paintComponent(Graphics g){ //override in JPanel
super.paintComponent(g);
//do what ever you need to do here to draw your graphics.
}I prefer to do all of my drawing to a BufferedImage and then use drawImage to show the image (off screen rendering):
public void paintComponent(Graphics g){ //override in JPanel
g.drawImage(myImage, 0, 0, this);
}

I can't figure out the Keynote title option. I'm a newbie so forgive my ignorance. I want to put an image in the swing arm, but I can't figure it out.

I even tried opening in Motion and inserting it there, but when I bring it back to fc it's not there. I also want to change the background to an image or at least solid white. When I put an image in the Dropzone it doesn't show up. Any help would be GREATLY appreciated!

To change the title background to use a clip in the drop zone, do just as Jim said.
Also, place the clip that want to appear in the "swing arm" right below the title in the timeline.

Animated GIF Image on a JPanel.

How can I display an animated GIF image on a JPanel? It should animate after displaying.

I think this code should display an animated GIF image on a JPanel.
-Mani
import javax.swing.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.*;
public class Animation {
public static void main(String args[]) {
JLabel imageLabel = new JLabel();
JLabel headerLabel = new JLabel();
JFrame frame = new JFrame("JFrame Animation");
JPanel jPanel = new JPanel();
//Add a window listner for close button
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
// add the header label
headerLabel.setFont(new java.awt.Font("Comic Sans MS", Font.BOLD, 16));
headerLabel.setText("Animated Image!");
jPanel.add(headerLabel, java.awt.BorderLayout.NORTH);
//frame.getContentPane().add(headerLabel, java.awt.BorderLayout.NORTH);
// add the image label
ImageIcon ii = new ImageIcon("d:/dog.gif");
imageLabel.setIcon(ii);

How to use a backgroud image in a JPanel.....

hi,
How can I display a background image for a JPanel.....
I have searched this forum but all solutions I found are where JPanel at the end has to be displayed on a frame in an application...
I need to use JPanel on Applet.......
Actually I am switching JPanels on JApplet as screens for a game....
I need to display background image for one of the JPanel class that has to be called by an Applet class....
Thanks a lot for any help.

Thanks a lot for your help.
How do we specify URL to use an image from net. Is itt like I open an image file on some website & use its address? Kindly add here some website too so that its more clear for me.
Thanks a lot for any help & all help your provided previously.

I had all photos on a Windows desktop. Got a mac laptop, installed LR5, and put all images from Windows onto an external hard drive. When I go to import them into LR on the Mac, they are all locked. Help, please. Thanks

I had all photos on a Windows desktop. Got a mac laptop, installed LR5, and put all images from Windows onto an external hard drive. When I go to import them into LR on the mac, they are all locked. Help, please!

"I plugged the external into the Mac and moved a folder of images onto the desktop. It looks like it went from read only to not locked. Is this possible?"
Yes, that's exactly what happened. If you buy another drive, you could copy from your existing drive to the new and your files will be read/write. The new drive will have to be formatted as an HFS drive (that's the Mac's format). If you need to format it, you use Disk Utility which is in the Utilities folder on your Mac. Be careful with that -- it wipes out whatever is currently on the drive. Make sure you format the right drive.
I keep all my images on an external drive, too. In fact, I have two matching drives and sync them so I always have a backup.

How do I draw an image on a JPanel?

To be honest I have no idea even where to start. I tried hacking through the tutorials but it just didn't help me (normally they do, I don't what's up).
Anyway, so what I'm trying to do is build a game. The Graphics2D is great for simple shapes but drawing characters is getting kind of ridiculous (tedious + difficult + looks bad). So, I need to figure out how to display an image on a JPanel.
To that end I have several questions.
1 - What image type do I use? Like jpeg, bmp, gif, etc.
2 - How do I make parts of it transparent?
3 - How do I make it appear on the screen, given some coordinates on the JPanel?

To draw an image directly to a JPanel given certain coordinates, you have to create a custom JPanel and override its paintComponent() method. Like this:
class PaintPanel extends JPanel{
public void paintComponent(Graphics g){
super.paintComponent(g);
//painting code goes here}
}Java can load in and draw GIF and JPEG images. If you decide to use GIF files, any good image editor like Adobe Photoshop should be able to make them transparent for you before the fact. If you want to set transparency within your java program you will have to create a BufferedImage and make certain colors within it transparent, but I would like to know how to do that as much as you do.

How to put an image in a data grid in Flex Builder 2

Hi All,
I need to populate a data grid with some text data received
from a web service and, in a particular column of the datagrid, I
have to put an image depending of a specific data returned me by
the web service.
It seems that there is the possibility to add an image in
data grid column with the cellRenderer properties, but this
property is available only for ActionScript 3.
I'm developing an application in Flex Builder 2 that run
ActionScript 2 and cellRenderer properties is not available. Is it
right?
If no, I will can use this cellRenderer properties in my
application. Please, can you show me an example?
If yes, there is a way to insert an image in datagridcolumn
with ActionScript 2?
Thank you very much
Regards

Flex Builder 2 uses Actionscript 3.
You will need to write a renderer for for this column.
There are a lot of examples of datagrids with images in them.
here is one from the livedocs

How to put an image in the popup help of a page item?

I am using APEX 2.2. I want to put an image in the help text of a page input item.
This is the help text:
Some help text....
<img src="&APP_IMAGES.auto_lov.jpg" />This is rendered as:
<img src="wwv_flow_file_mgr.get_file?p_security_group_id=0&p_flow_id=103&p_fname=auto_lov.jpg" />As you can see, the application id is not returned.
If I put exactly the same text in a html region, the image is correctly displayed:
<img src="wwv_flow_file_mgr.get_file?p_security_group_id=844129086577364&p_flow_id=103&p_fname=auto_lov.jpg" />So, is it possible at all to put in image in the popup help text of a page item?

I solved it by putting the jpg file in an images directory on the web server instead of in the database. Not really what I want, but it works.
<img src="&IMAGE_PREFIX./apps/auto_lov.jpg" />
