Java GUI Displaying Image Icon
Dec 2, 2014
how to display a jpg image on a through a Jlabel. I am sure it is a simple error but I am still new to GUI's. line 31 to 35 you can see the ImageIcon and file wrapped in the JLabel. I verified its in the correct location and file name, but usually fails (i thought) when it is not correct.
Java Code:
import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
[code]....

I developed a simple java gui . On running a frame opens with 5 buttons and each button opens another frame when selected. There are no errors and frames open and close as required however i see that only the main program frame has the icon and title that i assigned and the frames bieng called through the buttons have the default frame with java icon and no title although it's been specified in the code of these called frames. When these called frames are executed individually though the program the title and icon are displayed.

I recently made a game. But, I want to package it and give it to my friends. I know that I can create a jar of it and add the images to the folder, but what I would absolutely love is for it to just be a picture with the game name and click to run. The second thing is to replace that java icon to an icon of my preference, which I have been told numerous times to do with
frame.setIconImage(Image image)
which does not work for me.

I've an image memorized into a databas in tinyblob form.
I call it in java in this mode:
Product p = new Product();
...
p.setImgByte(rs.getByte("ImmagineByte"));
(p is a javabean, and imgByte is a byte format variable)
Once done that, what i've to do for show it into a swing label?
I've already setted an image retrieving it from an url in this mode
PHP Code: Image img = ImageIO.read(new URL(a.getImmagine()));
Image resizedImage = img.getScaledInstance(imgContainer.getWidth(), imgContainer.getHeight(), Image.SCALE_SMOOTH);
imgContainer.setIcon(new ImageIcon(resizedImage)); mh_sh_highlight_all('php');
But i don't know how to do the same thing with a byte format image inteasd of the url...

How would I go about erasing the first buffered image before displaying the second one and eventually a third and fourth so that it appears the image is moving across the screen?
myBuffer.drawImage(myArray[0].getImage(), xPos, yPos, null);
myBuffer.drawImage(myArray[0].getImage(), xPos + width, yPos, null);
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
public class KarelPanel extends JPanel {
private static final int WIDTH = 395, HEIGHT = 391; //constants

I'm currently following this Java tutorial:[URL]
I'm at the Image part of this chapter and I wrote/copied these 2 classes:
[URL]
The error:
Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(Unknown Source)
at image.Board.<init>(Board.java:17)
at image.Image.<init>(Image.java:10)
at image.Image.main(Image.java:20)
I'm fairly certain the problem is the path in this piece of code:
ImageIcon ii = new ImageIcon(this.getClass().getResource("C:GebruikersKristofferworkspaceImagessrcimageNature.jpeg"));
I've done some research and found that I should place the image in the same folder as my .java files, which I did [URL] but the problem still persists.

I have been reading some java guides here [URL] .... and was trying to put a bit of what I have learnt into practice but am having some difficulty. Basically, using netbeans IDE I have created a new jFrameform so that I can place swing components in design mode. What I want to create isnt overly complicated but I just cant seem to get it. In design I have simply added a panel and a button. When I press the button I want to display an image I have located at:
/resources/images/numbers/1.png.
This is my code so far (most of it has been automatically generated from me adding things via design mode:
/*

* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package test;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;
[Code] ....
I assume I need something like below somewhere , do i need to create a draw method? if so how do I call it as it is expecting graphics2d as a parameter, what would I pass into it?
BufferedImage img = null;
try {
img = ImageIO.read(new File("/resources/images/numbers/1.png"));
} catch (IOException e) {
}

I am writing code for a simple java game. The problem I am running into is that I have a moving icon (J button) that is controlled using the keyboard (arrows) and I also have stationary icons (J button). Is there a way to keep the moving icon from passing over the stationary icon? I would like the stationary icon to act like a wall.

my web browser isn't displaying any web page. When I create the method editorPane.setPage(), it takes forever (about 20 seconds) to show nothing. It'll load the web browser after the 20 seconds of waiting. Here is my code:
public class Browser extends JInternalFrame {
/**
*
*/
private static final long serialVersionUID = 4589041456161585394L;
public Browser() {
super("Browser", true, true);
this.setLayout(new BorderLayout());
this.setVisible(true);
this.setSize(Desktop.getSingletonInstance().getWidth(), Desktop.getSingletonInstance().getHeight());

I have been given a task to scan the contents of a websites source code, and use delimiters to extract all hyperlinks from the site and display them. We havent been told anything about how to do this so after some looking around online this is what I have so far:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Scanner;
[Code] ....
So my program can extract each line from the source code of a website and display it, but realistically I want it to extract each WORD as such from the source code rather than every line. I've looked around online but I don't really know how it's done because I keep getting errors when I use input.read();
How to make it extract each word from the source code?

So I'm in the middle of creating a model program with voxels. I want to be able to see how the model looks like when I'm in for example my documents (not inside the real program). I want it to show an image of the model, just like a png file shows its image. I've tried looking around, but I've only found threads about changing exe files icon.
Image example:
So, is this possible in Java or do I need to use c/c++ (with JNA) to make this possible?
Or is it not possible at all?

So I have got a button and there is this property assigned to it:
button.setIcon(new ImageIcon("srcimage.jpg"));
The icon is not displayed in full, as it is larger than the button. What property can I use to resize the icon? I have tried few and it did not work.

Recently I have been working on an executable launcher. I tried to get the executable icons and set them on the JButtons. Still there are some problems. Here is a part of the code:
try {
button[i].setIcon(FileSystemView.getFileSystemView().getSystemIcon(new File(getConfig("path." + (i+1)))));
}
catch (NullPointerException ex) {
}
Here the getConfig() method is already defined to get a string in a "properties" file. However, the icons are very small and they don't fill the entire button.
How can the icon fill the entire button (for example, having a custom size of 48x48, or automatically filled the button)? The frame will not be resized.
Here is the whole code...
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.io.File.*;
[Code] ....

I have a problem I must solve and could not find an answer after a couple weeks of research, so here I am. I have created a custom Table Cell Renderer than extends DefaultTreeCellRenderer. The mission of this renderer is to set the branch icons depending on conditional statements. There are 3 conditions, and each one should render a different icon. These conditions must be tested against all branches in the tree. This means that using something like setOpenIcon() and setClosedIcon() will not work since it seems as though these methods set all branches to a specific icon (I could be wrong about that though). Below is the code for my custom. I made comments so it is easier to understand what I want to happen and what is not happening.
/**Custom Cell Render that will set the icons for the tree branches and the leafs*/
private TreeIconCellRenderer extends DefaultTreeCellRenderer{
public Component.getTreeCellRendererComponent(JTree tree, Object value,boolean selected,boolean expanded, boolean leaf, boolean row, boolean hasFocus){
//Get defaults in case there is no need to renderer
[Code] ...
What I really need to know is why the renderer is not differentiating between the leaves and branches. The logging statements I have added confirm that the branch block of code does not execute.
