    <p>I'm making a project and need a progress bar. I've got the class with the Timer and it runs fine when I include a main; but when I try to call it in the mainGUI method, it's all black until it hits 100% then appears.</p> <pre><code>package microproject.resources; import javax.swing.*; import java.awt.event.*; import java.awt.*; public class Timer extends JFrame { JProgressBar current; JTextArea out; JButton find; Thread runner; int num = 0; int length = 0; public Timer() { setTitle("Progress"); setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); length = Integer.parseInt(JOptionPane.showInputDialog(null, "How many seconds:")); JPanel p = new JPanel(new GridLayout(1,1)); p.setPreferredSize(new Dimension(300,65)); current = new JProgressBar(0, length); current.setPreferredSize(new Dimension(250,50)); current.setValue(0); current.setStringPainted(true); p.add(current); setVisible(true); setContentPane(p); pack(); setVisible(true); iterate(); } public void iterate() { while(num &lt; length +1) { current.setValue(num); try { Thread.sleep(1000); } catch(InterruptedException e) {} num += 1; } } public static void main(String[] args) { Timer f = new Timer(); } } </code></pre> <p>This is the code for the Timer Class ^</p> <pre><code>package microproject.resources; import javax.swing.*; import java.awt.event.*; import java.awt.*; public class GUIMain extends JFrame { public static void main(String []args){ GuiFrame(); } public static void GuiFrame(){ JFrame frame = new JFrame("Casino Royal3"); frame.setSize(811,577); frame.setDefaultCloseOperation(EXIT_ON_CLOSE); frame.setLayout(new GridLayout(2,1)); frame.setResizable(false); JPanel PNorth = new JPanel(new FlowLayout(FlowLayout.LEFT,0,0)); JPanel PSouth = new JPanel(new BorderLayout()); //Creating Image for Casino Button ImageIcon img1 = new ImageIcon("src\\Casino.jpg"); final JButton btn1 = new JButton(img1); btn1.setPreferredSize(new Dimension(550,274)); btn1.setMargin(new Insets(0,0,0,0)); PNorth.add(btn1, BorderLayout.EAST); btn1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { btn1.setIcon(new ImageIcon("src\\Casino2.jpg")); } }); //Creating Image for Sheridan Label ImageIcon img2 = new ImageIcon("src\\SHERIDAN_LOGO.jpg"); JButton btn2 = new JButton(img2); btn2.setMargin(new Insets(0,0,0,0)); PNorth.add(btn2); btn2.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { ImageIcon instruc = new ImageIcon("src\\Instructions.jpg"); JLabel instructions = new JLabel(instruc); JOptionPane.showConfirmDialog(null, instructions, "instructions", JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE); } }); JPanel timmus = new JPanel(new FlowLayout(FlowLayout.LEFT,0,0)); timmus.setPreferredSize(new Dimension(166, 273)); timmus.setBackground(Color.BLUE); ImageIcon time = new ImageIcon("src\\Timer.jpg"); JButton timer = new JButton(time); timer.setMargin(new Insets(0,0,0,0)); timer.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { Timer f = new Timer(); } }); timmus.add(timer); ImageIcon mus = new ImageIcon("src\\music.jpg"); JButton music = new JButton(mus); music.setMargin(new Insets(0,0,0,0)); timmus.add(music); JPanel games = new JPanel(new FlowLayout(FlowLayout.LEFT,0,0)); games.setPreferredSize(new Dimension(500,279)); games.setBackground(Color.BLUE); ImageIcon calculator = new ImageIcon("src\\Calculator.jpg"); JButton calc = new JButton(calculator); calc.setMargin(new Insets(0,0,0,0)); calc.setPreferredSize(new Dimension(166,273)); games.add(calc); calc.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { Calculator c1 = new Calculator(); } }); ImageIcon g1 = new ImageIcon("src\\250Hangman.jpg"); JButton game1 = new JButton(g1); //game1.setBackground(Color.WHITE); game1.setMargin(new Insets(0,0,0,0)); game1.setPreferredSize(new Dimension(166,273)); games.add(game1); game1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { Hangman h1 = new Hangman(); } }); ImageIcon g2 = new ImageIcon("src\\Minesweeper.jpg"); JButton game2 = new JButton(g2); // game2.setBackground(Color.WHITE); game2.setMargin(new Insets(0,0,0,0)); game2.setPreferredSize(new Dimension(166,273)); games.add(game2); PSouth.add(timmus, BorderLayout.CENTER); PSouth.add(games, BorderLayout.EAST); frame.add(PNorth, BorderLayout.NORTH); frame.add(PSouth, BorderLayout.SOUTH); frame.setVisible(true); frame.pack(); } } </code></pre> <p>That's the entire program, the Timer ActionListener is called "timer"</p> <p>Thanks in advance</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
