    <p>This is the first time I've gotten this. I've used these two simple lines of code so much, but for one reason or another, I cannot use the second; it won't work.</p> <pre><code>Secondary second = new Secondary(); second.setVisible(true); </code></pre> <p>When I try to do it, it says that the meathod "setVisible(boolean)" is undefined for second, when it really is not. Any ideas?</p> <p>Here is the "Secondary" class:</p> <pre><code>public class Secondary { private JFrame frmMyGames; /** * Launch the application. */ public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { try { Games window = new Games(); window.frmMyGames.setVisible(true); } catch (Exception e) { e.printStackTrace(); } } }); } /** * Create the application. */ public Games() { initialize(); } /** * Initialize the contents of the frame. */ private void initialize() { frmMyGames = new JFrame(); frmMyGames.setTitle("My Games - Executioner"); frmMyGames.setBounds(100, 100, 470, 250); frmMyGames.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); final JTextArea Games = new JTextArea(); Games.setEnabled(false); Games.setEditable(false); Games.setFont(new Font("Calibri", Font.PLAIN, 13)); Games.setText("Please load a game list."); GroupLayout groupLayout = new GroupLayout(frmMyGames.getContentPane()); groupLayout.setHorizontalGroup( groupLayout.createParallelGroup(Alignment.LEADING) .addComponent(Games, GroupLayout.DEFAULT_SIZE, 462, Short.MAX_VALUE) ); groupLayout.setVerticalGroup( groupLayout.createParallelGroup(Alignment.LEADING) .addComponent(Games, Alignment.TRAILING, GroupLayout.DEFAULT_SIZE, 199, Short.MAX_VALUE) ); frmMyGames.getContentPane().setLayout(groupLayout); JMenuBar menuBar = new JMenuBar(); frmMyGames.setJMenuBar(menuBar); JMenu mnFile = new JMenu("File"); menuBar.add(mnFile); JMenuItem mntmLoad = new JMenuItem("Load List"); mntmLoad.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { Games.setText(""); Games.setEnabled(true); String directory = "C:/Program Files/Executioner/saves/games.ex"; BufferedReader reader = null; try { reader = new BufferedReader(new FileReader(directory)); Games.append(reader.readLine()); Games.append("\nUsername: " + reader.readLine()); Games.append("\nPassword: " + reader.readLine()); Games.append("\n"); Games.append(reader.readLine()); Games.append("\nUsername: " + reader.readLine()); Games.append("\nPassword: " + reader.readLine()); Games.append("\n"); Games.append(reader.readLine()); Games.append("\nUsername: " + reader.readLine()); Games.append("\nPassword: " + reader.readLine()); } catch (FileNotFoundException e1) { e1.printStackTrace(); } catch (IOException e1) { e1.printStackTrace(); } String line = null; try { while ((line = reader.readLine()) != null) { } } catch (IOException e1) { e1.printStackTrace(); } } }); mnFile.add(mntmLoad); JMenuItem mntmCloseList = new JMenuItem("Close List"); mntmCloseList.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { Games.setText("Please load a list..."); Games.setEnabled(false); } }); mnFile.add(mntmCloseList); } </code></pre> <p>}</p>

    1. COWhat class is Secondary **exactly**? Please post the fully qualified name, and code, if it is not a JDK class (which to my knowledge, it isn't)...

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).
