Swing/AWT/SWT :: Why Isn't Image Loading

Jun 20, 2014

I have added the image in the src and bin directories and cross-checked that the name of the image file is correct..Here is the main class

import javax.swing.*;
public class apples
{
public static void main(String args[])
{
JFrame frame = new JFrame();
MyDrawPanel wid = new MyDrawPanel();
frame.add(wid);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
frame.setSize(300,300);
}
}

and here is the class that does the image adding part

import java.awt.*;
import javax.swing.*;

public class MyDrawPanel extends JPanel
{
public void paintComponent(Graphics g)
{

Image image = new ImageIcon("b.png").getImage();
g.drawImage(image,20, 20, this);
}
}

Swing/AWT/SWT :: Loading Image From Relative Path

Mar 15, 2015

All I want to do is load an image into a swing JLabel and display it, but I'm going to have to make a JAR of the program and submit it for grading, so I need to be able to get the path of the image file relative to the JAR (at least I think that's how it works - I've never made a JAR before. Right now I'm just trying to load it from a path relative to my netbeans project). I've tried at least 20 different combinations of paths, file locations within the project, etc., but nothing works.

Anyways, here's the test class I've been using to try to figure this out in its current iteration. Right now the image I want to load is in src/resources and the class is in

src/imagedisplaytest
package imagedisplaytest;
import javax.swing.*;
import java.awt.*;
public class ImageDisplayTest extends JFrame {
private JLabel testLabel;
public ImageDisplayTest()

[Code]...

What's the best way to do this?

It loads and draws fine when I am using one image. But if I un-comment the others are try to draw the background of my game as intended, nothing gets drawn. I've played around with a number of different solutions but nothing works, I've had multiple images work in previous programs doing exactly the same thing and I really don't understand whats up.

Swing/AWT/SWT :: Saving And Loading Data Of Jtable

Apr 6, 2015

I am trying to make a program where a user can enter guests name for a hotel, the JTable includes rows for the name of the tenant, the room number, month etc.

I've made the table, however I am having some trouble in saving the data that I put into the table. I used jtextfield and a jbutton to but data into the jtable. I am trying to save the data, and load it just buy clicking a button.

table.setModel(new DefaultTableModel(
new Object[][] {
},
new String[] {
"Room", "Name", "Month", "Payment"//table rows
}
));

This is my basic table. And what I'm trying to do to save the data is:

DefaultTableModel model = new DefaultTableModel();
private JFileChooser myJFileChooser = new JFileChooser(new File("."));
private void saveTable() {
if (myJFileChooser.showSaveDialog(null) ==
JFileChooser.APPROVE_OPTION ) {
saveTable(myJFileChooser.getSelectedFile());

[Code] ....

When I run my program, I'm able to click on a button, and the dialog box will appear, I'm also able to save the data to a file. However when I click on the retieve data button I made the dialog box opens, the file is there, however when I click it, nothing happens.

Swing/AWT/SWT :: How To Scroll Image

Sep 30, 2014

I have a java swing application.

1. The human user of my application asks it to fire up a scanner which scans a paper document. The document is a filled in form.
2. The application then displays the scanned image to the human user.The image is displayed in a JScrollPane since it may be larger than the scroll pane.
3. The human user needs to locate a certain item in the form, for example a social security number, and enter it into a field in a data entry screen.Note that the image and the field appear on the same screen.

Of-course the social security number always appears in the same location in the image. Also the image needs to be the appropriate magnification and resolution to allow the human user to easily read and understand the item he is searching for in the image.

What is the best way to present the scanned image to the user such that he immediately sees the item he requires and can enter it into the data entry field.

Trying to get an image to display in a GUI.

try {
ByteArrayInputStream in = new ByteArrayInputStream(
transferWorker.bOutput
.toByteArray());
BufferedImage bufferedImage = ImageIO
.read(in);

[Code] ....

But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.

Swing/AWT/SWT :: How To Update Image In Java GUI

Jul 10, 2014

I have a GUI with several buttons and I'm using NetBeans GUI Builder to do. At the click of one of these I would like for it to open another frame containing a picture. So I associate a listener (actionPerformed) the button and when clicked it opens actually post the new frame.

In the new frame I waxed a JLabel and then I associate the image of the label. I saw that to do that NetBeans generates this code:

label.setIcon(new javax.swing.ImageIcon(getClass().getResource("/img/tree.png")));

My problem is that the picture is overwritten several times during the execution of the program is not changed yet in the frame. That is, in the new frame is always displayed an old version of the image.

I have an image that is created every time I click on the button (it always has the same name and same path). Basically I have a generic tree on which I perform the operations (add, remove, etc..). When I click on the button I call a method that generates the image of the tree (using Graphviz). So I have one image that changes over the time...

How can I do so that the image is always up to date?

The Code:

package View;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
public class AlberoIpotesi extends javax.swing.JFrame {

[Code] ....

Swing/AWT/SWT :: Moving Image Left Or Right

Mar 11, 2014

I can't find any resource on the net about a simple Java code just to move a gif image left or right. I've already accomplished the up, down, and center and they're working fine, thus, I'm still struggling with moving the image left or right. Here's the code.

public class MoveIt extends Applet implements ActionListener
{
private Image cup;
private Panel keypad;
public int top = 10;
public int left = 10;

[Code] ....

I remember in Visual BASIC it's easily achieved by NameOfImage.left = NameOfImage.left - 10 to move left and NameOfImage.left = NameOfImage.left + 10.

Swing/AWT/SWT :: How To Paint Image On Frame

Mar 8, 2015

I simply want to paint an image on my frame, just once each time the paint() method is called, but how to call the paint method in any good way. This is how it looks:

import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;

[Code] ....

I have a frame in another class, and from my assumption I need to somehow tell my paint method to paint on that specific frame right?

Swing/AWT/SWT :: Displaying Image Using ImageIcon?

Jul 5, 2014

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.
