QSignalBlocker can be used wherever you would otherwise use a pair of calls to blockSignals(). It blocks signals in its constructor and in the destructor it resets the state to what it was before the constructor ran.
blocker = QSignalBlocker(someQObject) # no signals here
is thus equivalent to
wasBlocked = someQObject.blockSignals(True) # no signals here someQObject.blockSignals(wasBlocked)
except the code using
QSignalBlocker is safe in the face of exceptions.
