Collecting threads in Qt

Question

I am looking for a way to get all threads created by one of my class to let me use them (threads are created dynamically depending on the user and I can't predict how many will be working while my application is working). Is there a good way to get all thread objects pointers and put them in one place so I can manipulate those threads?

QList<QThread*> QObject::findChildren <QThread*> () const

To find all child QThread's
