    <p>I'll give all. The error was, that you set the String <code>string</code>, not the JLabel <code>label</code>.</p> <p>Such behaviour, of something not having a GUI effect, could also have been caused by a missing <code>invokeLater</code> in <code>actionPerformed</code>.</p> <p>You made classes for the used objects to set specific properties. That is a burocratic waste, hence I have rewritten it a bit.</p> <p>If you resize the window, you'll see that the GridLayout manager again layouts, so that the JButton appears at its original position. You can use absolute positionwing with <code>setLayout(null)</code> using individual <code>setLocation</code>s.</p> <pre><code>public class JavaGUI extends JPanel { private JPanel control; private JLabel keys; public JavaGUI() { setLayout(new GridLayout(0, 1)); keys = new JLabel("Original starting value."); keys.setHorizontalAlignment(SwingConstants.CENTER); add(keys); control = new JPanel(); control.setPreferredSize(new Dimension(200, 100)); control.setMinimumSize(new Dimension(200, 100)); control.setLayout(null); JButton button = new JButton(new AbstractAction("Update") { @Override public void actionPerformed(ActionEvent e) { System.out.println("Command: " + e.getActionCommand()); keys.setText(String.valueOf(System.nanoTime())); //keys.label.setText(keys.string); //remove comments cause button move JButton j = (JButton) e.getSource(); j.setLocation(j.getX() + 10, j.getY() + 10); } }); button.setBounds(10, 10, 90, 24); control.add(button); add(control); } public static void main(String[] args) { final JFrame f = new JFrame("JavaGUI"); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.add(new JavaGUI()); f.pack(); f.setLocationRelativeTo(null); EventQueue.invokeLater(new Runnable() { @Override public void run() { f.setVisible(true); } }); } } </code></pre> <p>P.S. I have seen considerably worse code. This is actually neat code with only the superfluous classes.</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).
