Body
The <code>ScheduledThreadPoolExecutor</code> allows you to execute your task right away or schedule it to be executed later (you can set periodical executions also). So, if you will use this class to stop your task execution keep in mind this: <ol> <li>There is no way to guarantee that one thread will stop his execution. Check the Thread.interrupt() documentation.</li> <li>The method <code>ScheduledThreadPoolExecutor.shutdown()</code> will set as canceled your task, and it will not try to interrupt your threads. With this method you actually avoid the execution of newer tasks, and the execution of scheduled but not started tasks.</li> <li>The method <code>ScheduledThreadPoolExecutor.shutdownNow()</code> will interrupt the threads, but as I said in the first point of this list ...</li> </ol> When you want to stop the scheduler you must do something like this: <pre><code> //Cancel scheduled but not started task, and avoid new ones myScheduler.shutdown(); //Wait for the running tasks myScheduler.awaitTermination(30, TimeUnit.SECONDS); //Interrupt the threads and shutdown the scheduler myScheduler.shutdownNow(); </code></pre> But what if you need to stop only one task? The method <code>ScheduledThreadPoolExecutor.schedule(...)</code> returns a <code>ScheduleFuture</code> that is a representation of your already scheduled task. So, you can call the <code>ScheduleFuture.cancel(boolean mayInterruptIfRunning)</code> method to cancel your task and try to interrupt it if you need to.

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.
