Java Swing GridLayout Change Grid Sizes

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);
}
}

Same idea's from Andrew Thompson answer but with some minor text alignment changes and hover effect

when I make a popup menu with JPopupMenu it quits my file explorer page that I made and goes back to the main page(desktop)

I have tried telling it to dispose the file explorer and recreate it works but I cannot seem to get my file image on it now any help in making it not quit in the first place?

JTable column labels not printing

I have a JTable that I am using to display data from my database as a print preview. I can get it to print how I want except that the column headers wont print no matter what I try. I add my JTable to a JScrollPane, I have even gone so far as to add my JScrollPane to another JPanel which gets added to another JPanel with everything .setVisible(true).
After extensively traversing the Google-verse, the only solution I have found was here but I am already doing what they said. Here is my code so far:
public class PrintPreview extends JDialog implements ActionListener
{
private JTable infoTable;
private boolean printed;
private int windowWidth;
private int windowHeight;
JPanel scrollerPanel;
JPanel dataPanel;
private int[] idList;
private Connection conn;
private JScrollPane scroller;
private JButton printButton;
public PrintPreview(int[] tIds, Connection tConn)
{
printed = false;
idList = tIds;
conn = tConn;
setupFrame();
setupScroller();
setupButtons();
this.pack();
this.setVisible (true);
}
//returns true if printed, false otherwise
public boolean getCloseValue()
{
return printed;
}
private void setupFrame()
{
this.setTitle("Edit Data");
this.setSize (800, 700); //Width, Height
this.setLocationRelativeTo(null); //Centers the JFrame on the screen
this.setLayout(new BoxLayout(this.getContentPane(), BoxLayout.Y_AXIS));
this.setResizable(false);
this.setModalityType(APPLICATION_MODAL);
this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
//Gets the size of the contentPanel of the frame
Insets inset = this.getInsets();
windowWidth = this.getSize().width - (inset.left + inset.right);
windowHeight = this.getSize().height - (inset.top + inset.bottom);
}
private void setupScroller()
{
scrollerPanel = new JPanel();
scroller = new JScrollPane (setupTable(), JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
infoTable.setFillsViewportHeight(true);
scroller.setSize(windowWidth, windowHeight - 120);
scroller.setMinimumSize(new Dimension (windowWidth, windowHeight - 120));
scroller.setMaximumSize(new Dimension (windowWidth, windowHeight - 120));

Can someone please tell me what I am doing wrong?

Okay, after much screwing around, I got "something" to work. The "core" problems seem to come down to
Creating multiple instance of the JTable
"add" the JTable to the JScrollPane (scroller.add(setupTable());), as apposed to setting it as the screen pane's viewport's view
Addition, unnecessary UI elements which just made it more difficult to understand the code then was required
This example just dumps the output to a file, but it should work just fine for printing.

How to make this text area show which toggle buttons are selected?

Please can someone help me, I'm trying to make a seat reservation part for my cinema ticket system assignment ... so the problem is i want the text of the button to show in the text area when selected and not show only the specific text when deselected .. but when i deselect a button the whole text area is cleared.
For e.g. when I select C1, C2, C3 - it shows in the text area correctly, but if I want to deselect C3, the text area must now show only C1 & C2. Instead, it clears the whole text area!
Can anyone spot the problem in the logic?

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
