Body
How about using a timer, such as <a href="http://docs.oracle.com/javase/7/docs/api/javax/swing/Timer.html" rel="noreferrer"><code>javax.swing.Timer</code></a>? (Do not make mistake in the import, there are more Timer classes.) <pre><code>public static void main(String... args) throws InterruptedException { final DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); int interval = 1000; // 1000 ms new Timer(interval, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { Calendar now = Calendar.getInstance(); System.out.println(dateFormat.format(now.getTime())); } }).start(); Thread.currentThread().join(); } </code></pre> This will simply execute the body of the ActionListener every second, printing the current time. The <code>Thread.join</code> call on the last line is not universally necessary, it's just needed for this example piece of code to run until the process is manually stopped. Otherwise, it would immediately stop. In a real application, in case it's a Swing app, then the timer should handle threading by itself, so you won't have to worry about it. <hr> <h2>Edit</h2> Integrating the above sample into your application is fairly simple, just add it into the <code>initGUI</code> method and instead of printing the current time to System.out set change the text of the given label: <pre><code>public void initGUI() { setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); setPreferredSize(new Dimension(800, 600)); setLayout(null); Calendar now = Calendar.getInstance(); tijd = new JLabel(dateFormat.format(now.getTime())); tijd.setBounds(100, 100, 125, 125); window.add(tijd); new Timer(1000, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { Calendar now = Calendar.getInstance(); tijd.setText(dateFormat.format(now.getTime())); } }).start(); pack(); } </code></pre>

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.
