i have an URL image, and i want to display it in a panel.
How can i do it ?
One way to achieve this would be to use the URL class to grab the image from the web, create your ImageIcon object and then add it onto your JPanel,
Code is untested, but should demonstrate what you need to do.
URL img = new URL("http://www.example.com/whatever.jpg");
ImageIcon image = new ImageIcon(img);
JLabel label = new JLabel("", image, JLabel.CENTER);
JPanel panel = new JPanel(new BorderLayout());
panel.add( label, BorderLayout.CENTER );

I am creating a profile page. At the left, I have added a jlabel containing a background image to my jpanel. Now over this panel, I want to add another jlabel for the icon. However, it is not showing up. Please help me.
P.s: This is only part of the code
public CustomerProfile()
{
super("Customer Profile");
setLayout(new BorderLayout());
//PROFILE DETAILS JPANEL
jpProfile = new JPanel();
add(jpProfile, BorderLayout.WEST);
//BACKGROUND IMAGE OF THE PROFILE JPANEL
ImageIcon background_img = new ImageIcon("background.jpg");
Image img = background_img.getImage();
Image tempImg = img.getScaledInstance(350, 600, Image.SCALE_SMOOTH);
background_img = new ImageIcon(tempImg);
background = new JLabel("",background_img,JLabel.CENTER);
jpProfile.add(background);
//PROFILE ICON
ImageIcon profImg = new ImageIcon("female.png");
jlProfileIcon = new JLabel();
jlProfileIcon.setIcon(profImg);
//ADDING PROFILE ICON TO JPANEL
jpProfileIcon = new JPanel();
jpProfileIcon.add(jlProfileIcon);
//jpProfile.setOpaque(false);
//jpProfileIcon.setOpaque(false);
jpProfileIcon.add(jlProfileIcon);
background.add(jpProfileIcon);
}
By default only a JPanel uses a layout manager.
The JLabel does not use a layout manager so the size/location of any component added to the label is not changed. The default size of a component is (0, 0) so there is nothing to paint.
Try:
background = new JLabel("",background_img,JLabel.CENTER);
background.setLayout( new BorderLayout() ); // added
…
background.add(jlProfileIcon);
The following code is not needed:
//jpProfileIcon = new JPanel();
//jpProfileIcon.add(jlProfileIcon);
That is you don't need to create a JPanel, just to add the label to it.
A better option is to paint the background image onto a panel and then you can just add your label normally to the panel. See: Background Panel for a class that implements this functionality.
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.
My program captures the screen's images, resizes and represents them in a JoptionPane icon filed so that the user can decide weather or not to save them.
The prob is that after performing Joption.cancel, the icon shows the previous image the next time the user captures the screen image. in Joption.ok case it works fine.
Any idea why this happens? the snapshots themselves are well rendered(every snapshot captures the very current screen image but the icon shows the previous one once cancel has been clicked) .
rszedSnp=ImageMagick.resize(origSnp_name,30);
ImageIcon icon=new ImageIcon(rszedSnp);
String userIput = (String)JOptionPane.showInputDialog(
new JFrame(),
"Save as:\n",
"taking screen shot",
JOptionPane.PLAIN_MESSAGE,
icon ,
null,
origSnp_name);
I've resolved the problem by using JDialog, with an implemented JPanel containing a JLabel holding the image, instead of using an image icon in the JOptionPane#showInputDialog function. .
BufferedImage img = ImageIO.read(new File(image));
resize(img);
JLabel lbl = new JLabel(new ImageIcon(img));
lbl.setVisible(true);
JPanel imgPan = new JPanel();
imgPan.add(new JScrollPane(lbl))
JDialog dialog = new JDialog();
JPanel globalPan = new JPanel(new GridLayout(2,2));
globalPan.add(imgPan);
dialog.add( globalPan );
dialog.pack();
dialog.setVisible(true);
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
class image {
image()
//constructor {
Frame f=new Frame("Image");
//Frame
f.setSize(500,500);
f.setVisible(true);
Panel p =new Panel();
//Panel
f.add(p);
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);
}
public static void main(String [] args) {
image obj = new
}
}
What would be the most appropriate image type to display a jpg image (loaded from a local folder) on a JPanel?
Cheers.
ImageIcon image = new ImageIcon("image/pic1.jpg");
JLabel label = new JLabel("", image, JLabel.CENTER);
JPanel panel = new JPanel(new BorderLayout());
panel.add( label, BorderLayout.CENTER );
You could use a javax.swing.ImageIcon and add it to a JLabel using setIcon() method, then add the JLabel to the JPanel.
I'd probably use an ImageIcon and set it on a JLabel which I'd add to the JPanel.
Here's Sun's docs on the subject matter.
I would use a Canvas that I add to the JPanel, and draw the image on the Canvas.
But Canvas is a quite heavy object, sine it is from awt.
You could also use
ImageIcon background = new ImageIcon("Background/background.png");
JLabel label = new JLabel();
label.setBounds(0, 0, x, y);
label.setIcon(background);
JPanel panel = new JPanel();
panel.setLayout(null);
panel.add(label);
if your working with a absolut value as layout.
