I am having issues with creating an custom imageIcon in Java using swing. The file-name works, but it appears that the ImageIcon isn't changing at all. Here is the code:
ImageIcon icon = new ImageIcon("Hnet.com-image.png");
JFrame frame = new JFrame("NumberPad");
frame.setIconImage(icon.getImage());
frame.setName("Pin Pad");
frame.setContentPane(new NumberPad().NumberPadPanel);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
Anyone got suggestions for what I should do?
You should make a compilable example.
public class IconCheck{
public static void main(String[] args){
JFrame frame = new JFrame("icon test");
ImageIcon icon = new ImageIcon("Hnet.com-image.png");
JLabel label = new JLabel(icon);
frame.setIconImage( icon.getImage() );
frame.add(label);
frame.pack();
frame.setVisible(true);
}
}
Does that show your icon in the JFrame? If yes, then does it update your JFrame icon?
You probably want your png to be used as a resource.
ImageIcon icon = new ImageIcon( IconCheck.class.getResource("/sample.png") );
It looks up the path on the classpath, which intellij knows how to include.

I have the following package: projectname/src/main/java/net/is/lms/project/frames
In the frame folder there is a java class called testframe and an icon called icontest.png (it's 87x84px)
I have the following code snippet:
package net.is.lms.project.frames;
import javax.swing.*;
public class testframe {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(530, 600);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
String url = "src/main/java/net/is/lms/project/frames/icontest.png";
ImageIcon icon = new ImageIcon(url);
JLabel label = new JLabel();
label.setIcon(icon);
frame.add(label);
}
}
When I create the frame, no icon gets displayed
I tried different paths and also adding it like that:
URL url = testframe.class.getResource("/net/is/lms/project/frames/icontest.png");
I don't have enough reputation to leave a comment.
Have you tried to put the images in the src/main/resources folder and loading them like in this example: link
I wanna upload my project, a card game to Github, and it has a picture from my hard drive as the game card table. Is there a way to compile/run and upload it without the code having the entire file path hard coded into it? As of now, its:
public static void main(String[] args){
JFrame frame = new JFrame();
JLabel panel = new JLabel(new ImageIcon("C:\\Users\\MyName\\Documents\\javaprojects\\Cardgame\\cardgameProject\\cardgameTableCanvas.jpg"));
frame.setSize(WIDTH,HEIGHT);
panel.setSize(WIDTH,HEIGHT);
frame.add(panel);
frame.setTitle("Test Canvas");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
CardgameTable sampleTable = new CardgameTable();
frame.add(sampleTable);
frame.setVisible(true);
}
I also don't want issues if this is pulled from Git by someone else, and I think that file path could do it.
This really depends on where your java code is located! There are several tools that allow you to create a URL object of a local file path, and these can be fed into ImageIcon creation!
If the image is in the same directory (folder) as you java code, then the following should work to ensure the file is referenced even on other machines:
URL cardgameCanvas = new File("cardgameTableCanvas.jpg").toURI().toURL();
JLabel panel = new JLabel(new ImageIcon(cardgameCanvas));
(For java 7+: Paths.get("cardgameTableCanvas.jpg").toUri().toURL())
This should allow you to reference the image by first creating a URL object that links to it, and passing that URL object to the new ImageIcon object!
Hope this helps!

Edit
You can also just do
JLabel panel = new JLabel(new ImageIcon("cardgameTableCanvas.jpg"));
;)
Edit 2
Your main would look something like this (if you wanted to go the "hard way"):
public static void main(String[] args){
JFrame frame = new JFrame();
URL cardgameCanvas = new File("cardgameTableCanvas.jpg").toURI().toURL();
JLabel panel = new JLabel(new ImageIcon(cardgameCanvas));
frame.setSize(WIDTH,HEIGHT);
panel.setSize(WIDTH,HEIGHT);
frame.add(panel);
frame.setTitle("Test Canvas");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
CardgameTable sampleTable = new CardgameTable();
frame.add(sampleTable);
frame.setVisible(true);
}
But since it works for you I would definetaly recommend just referencing the local document itself like this:
public static void main(String[] args){
JFrame frame = new JFrame();
JLabel panel = new JLabel(new ImageIcon("cardgameTableCanvas.jpg"));
frame.setSize(WIDTH,HEIGHT);
panel.setSize(WIDTH,HEIGHT);
frame.add(panel);
frame.setTitle("Test Canvas");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
CardgameTable sampleTable = new CardgameTable();
frame.add(sampleTable);
frame.setVisible(true);
}

Setting background color for a JFrame
(14 answers)
Closed 7 years ago.
I am trying to make a planner and want to change the background of my JFrame.
I have already tried frame.getContentPane().setBackground(Color.); but that doesn't seem to work.
Here is the code for the frame portion
`public Planner(){
frame = new JFrame();
main = new JPanel();
menu = new Menu(this);
frame.setPreferredSize(preferredSize);
frame.add(main);
frame.setJMenuBar(menu);
frame.pack();
frame.setVisible(true);
frame.setLocationRelativeTo(null);
frame.setIconImage(Toolkit.getDefaultToolkit().getImage("Icon.png"));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setTitle("Myva");
JLabel loading = new JLabel();
JOptionPane pane = new JOptionPane();
pane.showMessageDialog( null, "Hi. ");
name = pane.showInputDialog("What is your name:");
}
Thanks in advance
If I understand your question, then you could call JFrame.setBackground(Color) like
frame.setBackground(Color.BLUE);
If you want to change the color in a more visible manner, you can make it on a JPanel. Like,
public static void main(String[] args) {
JFrame frame = new JFrame();
JPanel panel = new JPanel();
panel.setBackground(Color.BLUE);
frame.add(panel);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(640, 480);
frame.setVisible(true);
}
which will give you a very BLUE window.
To change the color of your JFrame, use the following code:
frame.setBackground(Color.BLUE);
(Color doesn't have to be blue, I just used it as an example)
I have a question and I know it may seem simple but I spent 3 hours and still I am having trouble:
I am trying to add and remove image in Jlabel in java dynamically I am trying this code but I cant see any image loding on label what is wrong with my code and what can I do else?
public static void main (String[] args)
{
ImageIcon icon = new ImageIcon ("1.gif");
JFrame frame = new JFrame ("Nested Panels");
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
// Set up first subpanel
JPanel subPanel1 = new JPanel();
subPanel1.setPreferredSize (new Dimension(450, 100));
//subPanel1.setBackground (Color.green);
JLabel label1 ;
label1 = new JLabel ("Devil Left", icon, SwingConstants.CENTER);
label1.setHorizontalTextPosition (SwingConstants.LEFT);
label1.setVerticalTextPosition (SwingConstants.BOTTOM);
subPanel1.add (label1);
JPanel primary = new JPanel();
primary.setBackground (Color.blue);
primary.add (subPanel1);
frame.getContentPane().add(primary);
frame.pack();
frame.setVisible(true);
}
ImageIcon(String) assumes that the value is a File.
If the image is stored within the context of the Jar (or project if you're using NetBeans), then you will need to access the image via Java's resource management API, for example.
ImageIcon icon = new ImageIcon (YourProject.class.getResource("1.gif"));
If you're using Eclipse, the resource will need to be stored within the projects resource folder.
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);
