You want to process something while your application is in idle state? Look no more, and even no need to understand multithreading programming. This cheap trick is a fabulous replacement for thread (this is also mentioned in QTimer documentation):

 idleTimer = new QTimer( this );
 QObject::connect( idleTimer, SIGNAL(timeout()), SLOT(idle()) );
 idleTimer->start( 0, FALSE ); 

Of course this is rather quick-and-dirty. But still on most cases it works rather well. Or, use the real QThread if you don't like.
