[Qt-interest] QThreadPool, Qrunnable and Signals/Slots

[Michael Jackson]

I would like to have a long running task put on another thread. I have done
things like this before with Qt but seem to get mixed up with Qthread,
Signals, Slots and Event Loops.

 My basic design is to have a "WorkerTask" derive from QObject and QRunnable
and implement the following:
  virtual void run()
signals:
 taskMessage(const QString &)
 taskProgress(int )
 taskFinished()
slots:
 cancelTask()

Then in the main GUI Class I plan to hook up the task with the GUI using
Signals/Slots
  connect( task, SIGNAL(taskMessage(cons QString &)), this,
SLOT(recTaskMessage(const QString &)) );
 ...  Connect the rest

QThreadPool->globalInstance()->start(task);


Is this going to work? I have read through the docs on QThreadPool and can
not get an indication if each thread in the QThreadPool runs its own event
loop? Without an event loop the Signals/Slots will not be delivered? Is that
correct? 

  Should I be tackling this in another way?

Thanks for any advice/pointers
