I have tried to create this progress bar:
public class ProgressBar extends JFrame{
private JButton fine = new JButton("Chiudi");
final JProgressBar jp;
JPanel body;
JLabel banner1;
JLabel banner2;
JPanel testo;
JTextArea areatesto;
JPanel provapannello;
JTextArea provatesto;
JPanel pannellofine;
public ProgressBar() {
super("loading");
setSize(440, 400);
setResizable(true);
Container content = getContentPane();
content.setBackground(Color.YELLOW);
body = new JPanel();
body.setLayout(new FlowLayout());
ImageIcon image1 = new ImageIcon("prova1.png");
banner1 = new JLabel();
banner2 = new JLabel();
banner1.setIcon(image1);
JTextArea prova = new JTextArea("bar", 2, 40);
prova.setBackground(Color.LIGHT_GRAY);
prova.setLineWrap(true);
body.add(banner1);
body.add(prova);
body.add(banner2);
banner.setBounds(30, 80, 120, 120);
testo = new JPanel();
areatesto = new JTextArea("Attendi Per Favore, Sto Preparando Il Tuo PDF", 2, 33);
areatesto.setLineWrap(true);
testo.add(areatesto);
ImagePanel progress_background = new ImagePanel("p.jpg");
UIManager.put("ProgressBar.background", new Color(29, 29, 29));
UIManager.put("ProgressBar.foreground", new Color(16, 95, 173));
UIManager.put("ProgressBar.selectionBackground", new Color(214, 214, 214));
UIManager.put("ProgressBar.selectionForeground", new Color(29, 29, 29));
jp = new JProgressBar();
jp.setUI(new BasicProgressBarUI());
jp.setBounds(0, 205, 434, 25);
jp.setMinimum(0);
jp.setMaximum(100);
jp.setStringPainted(true);
jp.setBorder(null);
progress_background.add(jp);
provapannello = new JPanel();
provatesto = new JTextArea("prova", 2, 70);
provatesto.setBackground(Color.LIGHT_GRAY);
provapannello.setBounds(0, 226, 500, 100);
provapannello.add(provatesto);
content.add(provapannello);
content.add(progress_background);
pannellofine = new JPanel();
pannellofine.add(fine);
pannellofine.setBounds(340, 330, 100, 100);
pannellofine.setVisible(false);
content.add(pannellofine);
content.add(testo);
content.add(body);
Thread runner;
jp.setValue(0);
setVisible(true);
public void setValue(final int j) {

#Override

}
};
SwingUtilities.invokeLater(target);
}
public static void main(String Args[]) {
ProgressBar p = new ProgressBar();
int i = 0;
while(true){
System.out.println("work");
try {
Thread.sleep(500);
} catch (InterruptedException ex) { }
p.setValue(i++);
}
}
I have tried to change the value of the ProgressBar with the method "setValue" but the bar does not increase, "while" cycles to infinity, but I see no change. what's wrong?
I've stripped out most of the unnecessary code (and fixed your compilation errors), and your example works (I've changed the delay and increment, because again, for reproduction purposes you shouldn't waste people's time)
import java.awt.BorderLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JProgressBar;
import javax.swing.SwingUtilities;
public class ProgressBar extends JFrame {
private JProgressBar progressBar;
public ProgressBar() {
super("loading");
setSize(200, 100);
Container content = getContentPane();
content.setLayout(new BorderLayout());
progressBar = new JProgressBar();
progressBar.setMinimum(0);
progressBar.setMaximum(100);
progressBar.setStringPainted(true);
progressBar.setBorder(null);
content.add(progressBar, BorderLayout.SOUTH);
setVisible(true);
}
void updateProgress(final int newValue) {
progressBar.setValue(newValue);
}
public void setValue(final int j) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
updateProgress(j);
}
});
}
public static void main(final String Args[]) {
ProgressBar myProgressBar = new ProgressBar();
int i = 0;
while (i <= 100) {
System.out.println("" + i + "%");
myProgressBar.setValue(i);
try {
Thread.sleep(50);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
break;
}
i = i + 5;
}
}
}
You should really have invested the time in creating an SSCCE
Also on a side note, you should follow this advice when handling InterruptedExcetions

I'm trying to create a program that lists movies in a Netflix style to learn Front-End coding.
How I want it to look in the end:
My guess is that every movie is a button component with an image a name label and a release year label.
I'm struggling to recreate this look. This is how it looks when I try it:
The navigationbar in my image is at the page start of a border layout. Below the navigationbar the movie container is in the center of the border layout.
My idea was creating a GridLayout and then create a button for each movie and adding it to the GridLayout.
You can recreate this with this code:
public class Main {
private static JFrame frame;
public static void main(String[] args) throws HeadlessException {
frame = new JFrame();
frame.setLayout(new BorderLayout());
frame.setBackground(new Color(32, 32, 32));
JPanel navigationPanel = createNavigationBar();
frame.add(navigationPanel, BorderLayout.PAGE_START);
JPanel moviePanel = createMoviePanel();
frame.add(moviePanel, BorderLayout.CENTER);
frame.setPreferredSize(new Dimension(1920, 1080));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setTitle("Example App");
frame.pack();
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
frame.setVisible(true);
}
public static JPanel createMoviePanel() {
JPanel moviePanel = new JPanel();
GridLayout layout = new GridLayout(0, 10);
layout.setHgap(3);
layout.setVgap(3);
moviePanel.setLayout(layout);
moviePanel.setBackground(new Color(32, 32, 32));
ArrayList<String> exampleList = new ArrayList<>();
// Add stuff to the example list
for(int i = 0; i < 120; i++) {
exampleList.add(Integer.toString(i));
}
final File root = new File("");
for(final String movie : exampleList) {
JLabel picLabel = new JLabel();
try {
File imageFile = new File(root.getAbsolutePath() + "\\src\\images\\" + "imageName.jpg"); // Try to find the cover image
if(imageFile.exists()) {
BufferedImage movieCover = ImageIO.read(imageFile);
picLabel = new JLabel(new ImageIcon(movieCover));
} else {
BufferedImage movieCover = ImageIO.read(new File(root.getAbsolutePath() + "\\src\\images\\temp.jpg")); // Get a temp image
picLabel = new JLabel(new ImageIcon(movieCover));
}
} catch (IOException e) {
e.printStackTrace();
}
JLabel movieName = new JLabel("New Movie");
movieName.setForeground(Color.WHITE);;
JButton movieButton = new JButton();
movieButton.setLayout(new GridLayout(0, 1));
//movieButton.setContentAreaFilled(false);
//movieButton.setBorderPainted(false);
//movieButton.setFocusPainted(false);
movieButton.add(picLabel);
movieButton.add(movieName);
moviePanel.add(movieButton);
}
return moviePanel;
}
public static JPanel createNavigationBar() {
JPanel navBar = new JPanel();
navBar.setLayout(new FlowLayout(FlowLayout.LEFT, 30, 20));
navBar.setBackground(new Color(25, 25, 25));
JButton homeButton = new JButton("Home");
homeButton.setContentAreaFilled(false);
homeButton.setBorderPainted(false);
homeButton.setFocusPainted(false);
JButton movieButton = new JButton("Movies");
movieButton.setContentAreaFilled(false);
movieButton.setBorderPainted(false);
movieButton.setFocusPainted(false);
// Add all the buttons to the navbar
navBar.add(homeButton);
navBar.add(movieButton);
return navBar;
}
}
I noticed that the GridLayout always tries to fit everything onto the window.
All that's needed is a properly configured JButton in a GridLayout.
E.G.
public static JPanel createMoviePanel() {
JPanel movieLibraryPanel = new JPanel(new GridLayout(0, 10, 3, 3));
movieLibraryPanel.setBackground(new Color(132, 132, 132));
int m = 5;
BufferedImage image = new BufferedImage(9 * m, 16 * m, BufferedImage.TYPE_INT_RGB);
for (int ii = 1; ii < 21; ii++) {
JButton picButton = new JButton("Mov " + ii, new ImageIcon(image));
picButton.setMargin(new Insets(0,0,0,0));
picButton.setForeground(Color.WHITE);
picButton.setContentAreaFilled(false);
picButton.setHorizontalTextPosition(JButton.CENTER);
picButton.setVerticalTextPosition(JButton.BOTTOM);
movieLibraryPanel.add(picButton);
}
return movieLibraryPanel;
}
Here is a complete source for the above with a tweak to put the year on a new line. It uses HTML in the JButton to break the button text into two lines.
The input focus is on the first button, whereas the mouse hovers over the '2009' movie:
import java.awt.*;
import java.awt.image.*;
import javax.swing.*;
class MovieGrid {
MovieGrid() {
JFrame f = new JFrame("Movie Grid");
f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f.setLocationByPlatform(true);
f.add(createMoviePanel());
f.pack();
f.setVisible(true);
}
public static JPanel createMoviePanel() {
JPanel movieLibraryPanel = new JPanel(new GridLayout(0, 10, 3, 3));
movieLibraryPanel.setBackground(new Color(132, 132, 132));
int m = 5;
BufferedImage image = new BufferedImage(
9 * m, 16 * m, BufferedImage.TYPE_INT_RGB);
for (int ii = 2001; ii < 2021; ii++) {
JButton picButton = new JButton(
"<html>Movie<br>" + ii, new ImageIcon(image));
picButton.setMargin(new Insets(0,0,0,0));
picButton.setForeground(Color.WHITE);
picButton.setContentAreaFilled(false);
picButton.setHorizontalTextPosition(JButton.CENTER);
picButton.setVerticalTextPosition(JButton.BOTTOM);
movieLibraryPanel.add(picButton);
}
return movieLibraryPanel;
}
public static void main(String[] args) {
Runnable r = new Runnable() {
#Override
public void run() {
new MovieGrid();
}
};
SwingUtilities.invokeLater(r);
}
}

Is it possible to initialize for example JPanel outside Window class?"
Yes. A different class might contain a method that creates & returns a JPanel.
Other tips:
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.
Application resources will become embedded resources by the time of deployment, so it is wise to start accessing them as if they were, right now. An embedded-resource must be accessed by URL rather than file. See the info. page for embedded resource for how to form the URL.
new Font("Verdana", Font.PLAIN, 20) Use defaults or logical fonts (E.G. Font.SERIF) unless the font is supplied with your app. as an embedded resource.
The loop and array of labels that are added to viewBreed suggest it should be a JList rather than a JPanel
layeredPane.removeAll(); .. Ugh.. Use a CardLayout as shown in this answer.
What is the purpose of the JLayeredPane? I expect it's unnecessary purely on the basis that there is so little use for them.
I'm trying to access the int myInt in this GUI form class from another class. The method does pass the input variable to myInt properly but I have not been able to make it visible to the other java file. I have been reading about scope and class declarations and have been able to muddle along up until now, but I am doing something wrong here. Nothing I have tried has worked.

I am getting both frames being displayed. But I am not getting the progressbar running when I press the login button.. Also I am not able to get the values of username and password fields into the powershell script.. My powershell code is given below stage1.ps1:
$username = $env:USER
$password = $env:PASS
$url = "https://www.jabong.com/customer/account/login/"
$ie = New-Object -com internetexplorer.application;
$ie.visible = $true;
$ie.navigate($url);
while ($ie.Busy -eq $true)
{
Start-Sleep 1;
}
$ie.Document.getElementById("LoginForm_email").value = $username
$ie.Document.getElementByID("LoginForm_password").value=$password
$ie.Document.getElementByID("qa-login-button").Click();
The web page is invoked when I click the login button.But I am not getting the values of credentials being passed in the swing window into it
Something strange happened to me. For some reason, it takes a long time(1.60900 seconds) till it runs the following line:
textArea = new JTextArea();
I declared textArea variable as globally.
This only happens in one window (Jframe). In others it does not happen.
