    <p>First of all, if you don't create a copy of the <code>Graphics</code> context, you shouldn't be disposing of it. This could actually prevent other parts of your application form been painted ;)</p> <p>Second of all. I would avoid extending from a top level container, like <code>JFrame</code>, apart from allowing you to draw under the frame/border decoration of the window, they aren't double buffered.</p> <p>Instead, I'd use something like a <code>JPanel</code> instead and override its <code>paintComponent</code> method. This will provide you with automatic double buffering.</p> <p>Because Swing is a single threaded framework, it is expected that all updates to the UI be executed within the context of the Event Diapatching Thread. </p> <p>This makes live a little difficult when it comes to try to do things like waiting and synchronizing paint updates.</p> <p>Luckly, Swing provides a <code>javax.swing.Timer</code> which allows you schedule an event for some time in the future. This can also be setup to repeat and regular intervals.</p> <pre><code>Timer timer = new Timer(40, new ActionListener() { public void actionPerformed(ActionEvent e) { // perform your required actions here } }); </code></pre> <p>Now, beware, the <code>actionPerformed</code> method is being executed with the context of the EDT, this means, that any long running/time consuming processing you do here may cause you UI to stop painting</p> <p>Take a look at </p> <ul> <li><a href="http://docs.oracle.com/javase/tutorial/uiswing/painting/" rel="nofollow">Performing Custom Painting</a></li> <li><a href="http://docs.oracle.com/javase/tutorial/uiswing/concurrency/initial.html" rel="nofollow">Intial Threads</a></li> <li><a href="http://docs.oracle.com/javase/tutorial/uiswing/concurrency/" rel="nofollow">Concurrency in Swing</a></li> </ul> <p>For more details...</p>

    1. CO@Sam This. Knowledge about the EDT is crucial in Swing programming. Also, about drawing directly into the `JFrame` - every JFrame has a "content pane" which by default is a JPanel. Either swap in your own JPanel or draw directly on the supplied one. Look at [`JFrame#setContentPane()`](http://docs.oracle.com/javase/7/docs/api/javax/swing/JFrame.html#setContentPane%28java.awt.Container%29) and [`getContentPane()`](http://docs.oracle.com/javase/7/docs/api/javax/swing/JFrame.html#getContentPane%28%29).

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).
