+\brief Execute a Job on a QThread. once or multiple times.
+
+QxtJob allows easily starting jobs on different threads.\n
+exec() will ask for the QThread to run the job on.
+The Qthread needs an event loop. 4.3 and later versions of Qt have
+a non virtual QThread with a default event loop, allowing easy deployment of jobs.
+
+\code
+QThread thread;
+thread.start();
+LockJob().exec(&thread);
