QThread does not indicate that an event dispatcher is created in start()

In the documentation for QThread::setEventDispatcher, it discusses that you can provide your own QAbstractEventDispatcher if one has not been installed already, and even alludes to one being automatically created, but doesn't outright state that one is created when QThread::start is called.

This makes it confusing for people whom may wish to manually drive the event loop of a QThread, as it is not clear that they can access the event dispatcher.
