    <p>In general, there is no mechanism to do this. However, I managed to get it working by subclassing <code>StyledText</code>. The new class is called <code>StyledTextWithListeners</code>. You can just rename it if you want ;) . However, you will have to use</p> <pre><code>styledText.addListenerByUser(int eventType, Listener listener); </code></pre> <p>to add you <code>Listener</code>s rather than</p> <pre><code>styledText.addListener(int eventTyle, Listener listener); </code></pre> <p>This is necessary to discriminate between <code>Listener</code>s added by you and those added by SWT upon creation.</p> <p>To remove all listeners <strong>added by the user (you)</strong> just call</p> <pre><code>styledText.removeAllListeners(); </code></pre> <p>Here is the code:</p> <pre><code>import java.util.HashMap; import org.eclipse.swt.SWT; import org.eclipse.swt.custom.StyledText; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Composite; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Event; import org.eclipse.swt.widgets.Listener; import org.eclipse.swt.widgets.Shell; public class MiniExample { public static void main(String[] args) { Display display = Display.getDefault(); final Shell shell = new Shell(display); shell.setLayout(new GridLayout(1, false)); StyledTextWithListeners text = new StyledTextWithListeners(shell, SWT.BORDER); text.setText("TEXT"); text.addListenerByUser(SWT.Verify, new Listener() { @Override public void handleEvent(Event arg0) { } }); text.removeAllListeners(); shell.pack(); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } } public static class StyledTextWithListeners extends StyledText { HashMap&lt;Integer, Listener&gt; listeners; public StyledTextWithListeners(Composite parent, int style) { super(parent, style); } public void addListenerByUser(int eventType, Listener listener) { addListener(eventType, listener); System.out.println("Adding: " + listener.getClass().toString()); if(listeners == null) listeners = new HashMap&lt;Integer, Listener&gt;(); listeners.put(eventType, listener); } public void removeAllListeners() { for(Integer type : listeners.keySet()) { System.out.println("Removing: " + listeners.get(type).getClass().toString()); removeListener(type.intValue(), listeners.get(type)); } listeners = new HashMap&lt;Integer, Listener&gt;(); } } } </code></pre> <p>It basically saves all the <code>Listener</code>s you add in a <code>HashMap</code> and removes them when you call <code>removeAllListeners</code>.</p> <p><strong>Keep in mind</strong> that I didn't take care of the case where you add a second <code>Listener</code> with the same <code>eventType</code> to the <code>StyledText</code> as done before. In this case, the old <code>Listener</code> will be replaced in the HashMap, but not removed from the <code>StyledText</code>. If this case can occur in your scenario, just add some code yourself.</p>

    2. COWhen I try to do the same thing with `Text`, I get an SWTException saying that subclassing is not allowed (Eclipse 3.6) but I don't when using a `StyledText`. Why? How do I overcome this? Also, will they perhaps one day throw the same exception when trying to subclass StyledText, making this impossible?

    3. COI got around the SubClassing exception by adding this method: protected void checkSubclass(){ }

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).
