    <p>I have given below a simple example on how to use <a href="http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fjface%2Foperation%2FIRunnableWithProgress.html" rel="nofollow">IRunnableWithProgress</a> along with a <a href="http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fjface%2Fdialogs%2FProgressMonitorDialog.html" rel="nofollow">ProgressMonitorDialog</a> to perform a task of unknown quantity. To start with, have an implementation to IRunnableWithProgress from where the actual task is performed. This implementation could be an inner class.</p> <pre class="lang-java prettyprint-override"><code>public class MyRunnableWithProgress implements IRunnableWithProgress { private String _fileName; public MyRunnableWithProgress(String fileName) { _fileName = fileName; } @Override public void run(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException { int totalUnitsOfWork = IProgressMonitor.UNKNOWN; monitor.beginTask("Performing read. Please wait...", totalUnitsOfWork); performRead(_fileName, monitor); // This only performs the tasks monitor.done(); } } </code></pre> <p>Now, a generic implementation to <em>ProgressMonitorDialog</em> can be created as below which could be used for other places where a progress monitor dialog is required.</p> <pre class="lang-java prettyprint-override"><code>public class MyProgressMonitorDialog extends ProgressMonitorDialog { private boolean cancellable; public MyProgressMonitorDialog(Shell parent, boolean cancellable) { super(parent); this.cancellable = cancellable; } @Override public Composite createDialogArea(Composite parent) { Composite container = (Composite) super.createDialogArea(parent); setCancelable(cancellable); return container; } } </code></pre> <p>Having got the required implementation, the task can be invoked as below to get it processed with a progress dialog.</p> <pre class="lang-java prettyprint-override"><code>boolean cancellable = false; IRunnableWithProgress myRunnable = new MyRunnableWithProgress(receivedFileName); ProgressMonitorDialog progressMonitorDialog = new MyProgressMonitorDialog(getShell(), cancellable); try { progressMonitorDialog.run(true, true, myRunnable); } catch (InvocationTargetException e) { // Catch in your best way throw new RuntimeException(e); } catch (InterruptedException e) { //Catch in your best way Thread.currentThread().interrupt(); } </code></pre> <p>Hope this helps!</p>

    1. COThanks, the IProgressMonitor.UNKNOWN is surely a good idea, I would be, however, be interested how to deal with cases, where performRead(..) would be a (blocking) framework method that does not accept a monitor on which I can call worked()

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).
