Detailed Description

QxtJob allows easily starting jobs on different threads.
exec() will ask for the QThread to run the job on. The Qthread needs an event loop. since version 4.4, QThread has a non pure run function with a default event loop, allowing easy deployment of jobs.

QThread thread;
thread.start();
LockJob().exec(&thread);
