Hey Ferran,
ControlObjects can distinguish between changes made to their internal
ControlDoublePrivate made through the ControlObject itself or via another
route (ControlObjectThread, ControlObjectSlave, or the plain old
ControlObject::set() static method).
You'll see that the valueChanged() method from m_pControl (its
ControlDoublePrivate) is connected to privateValueChanged.
privateValueChanged then checks if the sender for the change was itself. If
it is then it rebroadcasts the signal as a valueChangedFromEngine signal.
If not then it rebroadcasts it as a valueChanged signal. So
privateValueChanged is only used as a rebroadcaster of signals from
ControlDoublePrivate.
Hope that helps -- cheers,
RJ
