i wrote very simple code to display an icon of the grapes but still the code doesn't show me anything
here is my code
import javax.swing.*;
import java.awt.*;
public class Code {
ImageIcon ii = new ImageIcon("image/grapes2.jpg");
JLabel label = new JLabel("Grapes", ii, SwingConstants.CENTER);
JFrame frame = new JFrame("ImageIcon");
public void ui(){
label.setHorizontalTextPosition(SwingConstants.CENTER);
label.setVerticalTextPosition(SwingConstants.BOTTOM);
label.setIconTextGap(5);
label.setOpaque(true);
label.setBackground(Color.GRAY);
frame.setSize(2300,2300);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(label);
}
}
If image icon is not visible even after calling frame.setVisible(true) in the end then have a look at my another posts that is asked in the same context.
How to retrieve image from project folder?
Read image from another directory
Try
// Read from src/image folder
ii = new ImageIcon(ImageIO.read(getClass().getResource("/image/grapes2.jpg")));
label.setIcon(ii);
It's worth reading How to Use Icons and here is the sample directly from there.
ImageIcon icon = createImageIcon("images/middle.gif",
"a pretty but meaningless splat");
label1 = new JLabel("Image and Text", icon, JLabel.CENTER);
...
label3 = new JLabel(icon);
/** Returns an ImageIcon, or null if the path was invalid. */
protected ImageIcon createImageIcon(String path,
String description) {
java.net.URL imgURL = getClass().getResource(path);
if (imgURL != null) {
return new ImageIcon(imgURL, description);
} else {
System.err.println("Couldn't find file: " + path);
return null;
}
}

For e.g. Class file in directory named omega. Image in omega/images directory.

I'm trying to add a .gif image to a JButton, but can't seem to get the image to load when i run the code. I've included a screenshot. Included is the frame that's created. I'd really appreciate any help that can be provided. Stack is telling me I can't enter images yet, so it created a link for it. I'm also going to enclose the actual code here:
package java21days;
import javax.swing.*;
import java.awt.*;
public class ButtonsIcons extends JFrame {
JButton load, save, subscribe, unsubscribe;
public ButtonsIcons() {
super("Icon Frame");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
//Icons
ImageIcon loadIcon = new ImageIcon("load.gif");
ImageIcon saveIcon = new ImageIcon("save.gif");
ImageIcon subscribeIcon = new ImageIcon("subscribe.gif");
ImageIcon unsubscribeIcon = new ImageIcon("unsubscribe.gif");
//Buttons
load = new JButton("Load", loadIcon);
save = new JButton("Save", saveIcon);
subscribe = new JButton("Subscribe", subscribeIcon);
unsubscribe = new JButton("Unsubscribe", unsubscribeIcon);
//Buttons To Panel
panel.add(load);
panel.add(save);
panel.add(subscribe);
panel.add(unsubscribe);
//Panel To A Frame
add(panel);
pack();
setVisible(true);
} //end ButtonsIcon Constructor
public static void main(String[] arguments) {
ButtonsIcons ike = new ButtonsIcons();
}
} //end ButtonsIcon Class
enter image description here
The easiest way is.
Label or Jbutton and what ever else supports HTML 3.5
JLabel a = new JLabel("");
add that to your container.
Haven't figured out how to enter code sorry
I'm trying to add the image "Pic.png" to this JLabel "label1" and display it on the JPanel "panel1" on a JFrame "window1". But it when I hit run it doesn't display my image. Anyone help? (I read about adding it to the source file or something but I'm not really sure what I'm doing because I'm new to Java. Will it not be able to access the picture without the image being in the source?)
public class UIForIshidaQuery {
public static void main(String[] args) {
System.out.println("Running...");
JFrame window1 = new JFrame();
window1.setVisible(true);
window1.setSize(1080, 720);
window1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel1 = (JPanel) window1.getContentPane();
JLabel label1 = new JLabel();
panel1.setLayout(null);
ImageIcon image = new ImageIcon("C:\\Users\\BC03\\Pictures\\Saved Pictures\\Other\\Pic.png");
label1.setIcon(image);
label1.setBounds(500, 500, 500, 500);
panel1.add(label1);
}
}
The window should be set visible as the last call. Don't use null layouts1. This works.
import java.net.*;
import javax.swing.*;
public class UIForIshidaQuery {
public static String url = "http://i.stack.imgur.com/gJmeJ.png";
public static void main(String[] args) throws MalformedURLException {
System.out.println("Running...");
JFrame window1 = new JFrame();
window1.setSize(1080, 720);
window1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel1 = (JPanel) window1.getContentPane();
JLabel label1 = new JLabel();
//panel1.setLayout(null);
ImageIcon image = new ImageIcon(new URL(url));
label1.setIcon(image);
//label1.setBounds(500, 500, 500, 500);
panel1.add(label1);
window1.setVisible(true);
}
}
Java GUIs have to work on different OS', screen size, screen resolution etc. using different PLAFs in different locales. As such, they are not conducive to pixel perfect layout. Instead use layout managers, or combinations of them along with layout padding and borders for white space.
If you are using IntelliJ IDEA:
Right click your project root directory and select New > Directory;
Call the new directory 'resources' for example;
Right click the newly made directory and select Mark Directory As > Resources Root;
Add your image file in the directory;
Access your file properly:
CurrentClass.class.getClassLoader().getResource("pic.png").getFile();
The ImageIcon could be initialized like this:
File file = new File(CurrentClass.class.getClassLoader().getResource("pic.png").getFile());
BufferedImage image = null;
try {
image = ImageIO.read(file);
} catch (IOException e) {
e.printStackTrace();
}
ImageIcon imageIcon = new ImageIcon(image);
I am trying to make a very basic game with Java and I am having trouble displaying an image on a JFrame. It has worked in the past for me and now is not, i can't see what I did wrong.
I have tried printing the current working directory and changing where I get my image to match that. It is likely that the problem is not getting the image, since my (filefinder or filereader or something like that) can find it without problems, but I cannot correctly add it (the ImageIcon) to the JLabel, or that to the JFrame.
This is my code...
JFrame frame = new JFrame("no image");
ImageIcon image = new ImageIcon("C:/Documents and Settings/user/Desktop/hi/xD/JavaApplication2/image.png");
JLabel imagelabel = new JLabel(image);
frame.add(imagelabel);
The JFrame has been setVisible(true) and pack().
Could someone please help me understand what is wrong.
Your problem lies here:
ImageIcon image = new ImageIcon("C:/Documents and Settings/user/Desktop/hi/xD/JavaApplication2/image.png");
JLabel imagelabel = new JLabel(character);
You create an ImageIcon "image" but you create your JLabel with "character".
It should be:
JLabel imagelabel = new JLabel(image);
Try,
ImageIcon image = new ImageIcon("c:\\path\\image.png");
imagelabel = new JLabel(character, image, JLabel.CENTER);
frame.add(imagelabel);
Take a look at Tutorial - How to use Icons
import javax.awt.*;
import java.awt.*;
import java.awt.event*;
//class name image

p.addLayout(null);
ImageIcon ii=new ImageIcon("set your image path");
//ImageIcon is used to image Display .
Label l =new Label(ii);
p.add(ii);
p.setBounds(set you bounds);
//Like that(20,20,500,40);

Hey there, i have just tried to put an image that is taken with JFileChooser on a label; but it did not work the way i want to. Here is the code that i tried;
import java.io.*;
import javax.swing.*;
import java.util.*;
public class Main {
public static void main(String[] args) {
JFileChooser chooser = new JFileChooser();
JFrame frame = new JFrame("My Frame");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
chooser.showOpenDialog(null);
File file = chooser.getSelectedFile();
ImageIcon icon = new ImageIcon(file.getName());
JLabel label = new JLabel(icon);
// JLabel label2 = new JLabel("try try catch it");
panel.add(label);
// panel.add(label2);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
}
}
Any suggestion?
Close.
You will notice that when you look at file.getName() you see that it will give you the name of the file that you selected. You're looking for the path instead of the name of the file.
See if you can look in the API for File for how to get the path.
You should be using file.getPath() instead of file.getName(). You should also be doing your painting work in the EDT.
I'm trying to create a ImageIcon from a animated gif stored in a jar file.
ImageIcon imageIcon = new ImageIcon(ImageIO.read(MyClass.class.getClassLoader().getResourceAsStream("animated.gif")));
The image loads, but only the first frame of the animated gif. The animation does not play.
If I load the animated gif from a file on the filesystem, everything works as expected. The animation plays through all the of frames. So this works:
ImageIcon imageIcon = new ImageIcon("/path/on/filesystem/animated.gif");
How can I load an animated gif into an ImageIcon from a jar file?
EDIT: Here is a complete test case, why doesn't this display the animation?
import javax.imageio.ImageIO;
import javax.swing.*;
public class AnimationTest extends JFrame {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
AnimationTest test = new AnimationTest();
test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
test.setVisible(true);
}
});
}
public AnimationTest() {
super();
try {
JLabel label = new JLabel();
ImageIcon imageIcon = new ImageIcon(ImageIO.read(AnimationTest.class.getClassLoader().getResourceAsStream("animated.gif")));
label.setIcon(imageIcon);
imageIcon.setImageObserver(label);
add(label);
pack();
} catch (Exception e) {
e.printStackTrace();
}
}
}
This reads gif animation from inputStream
InputStream in = ...;
Image image = Toolkit.getDefaultToolkit().createImage(org.apache.commons.io.IOUtils.toByteArray(in));
You have to use getClass().getResource(imgName); to get a URL to the image file. Check out this tutorial from Real's HowTo.
EDIT: Once the image is loaded you have to set the ImageObserver property to get the animation to run.
Since this thread was just linked from a more current thread that had little to do with animated GIFs but got dragged OT, I thought I'd add this trivial source that 'works for me'.
import javax.swing.*;
import java.net.URL;
class AnimatedGifInLabel {
public static void main(String[] args) throws Exception {
final URL url = new URL("http://i.stack.imgur.com/OtTIY.gif");
Runnable r = new Runnable() {
public void run() {
ImageIcon ii = new ImageIcon(url);
JLabel label = new JLabel(ii);
JOptionPane.showMessageDialog(null, label);
}
};
SwingUtilities.invokeLater(r);
}
}
Hopefully it's not too late for this.
I managed to get the animated gif inside my JPanel this way:
private JPanel loadingPanel() {
JPanel panel = new JPanel();
BoxLayout layoutMgr = new BoxLayout(panel, BoxLayout.PAGE_AXIS);
panel.setLayout(layoutMgr);
ClassLoader cldr = this.getClass().getClassLoader();
java.net.URL imageURL = cldr.getResource("img/spinner.gif");
ImageIcon imageIcon = new ImageIcon(imageURL);
JLabel iconLabel = new JLabel();
iconLabel.setIcon(imageIcon);
imageIcon.setImageObserver(iconLabel);
JLabel label = new JLabel("Loading...");
panel.add(iconLabel);
panel.add(label);
return panel;
}
Some points of this approach:
1. The image file is within the jar;
2. ImageIO.read() returns a BufferedImage, which doesn't update the ImageObserver;
3. Another alternative to find images that are bundled in the jar file is to ask the Java class loader, the code that loaded your program, to get the files. It knows where things are.
So by doing this I was able to get my animated gif inside my JPanel and it worked like a charm.
