Detailed Description
The QRunnable class is an interface for representing a task or piece of code that needs to be executed, represented by your reimplementation of the run() function.
You can use QThreadPool to execute your code in a separate thread. QThreadPool deletes the QRunnable automatically if autoDelete() returns true
(the default). Use setAutoDelete() to change the auto-deletion flag.
QThreadPool supports executing the same QRunnable more than once by calling QThreadPool::tryStart(this) from within the run() function. If autoDelete is enabled the QRunnable will be deleted when the last thread exits the run function. Calling QThreadPool::start() multiple times with the same QRunnable when autoDelete is enabled creates a race condition and is not recommended.
