QMqttClient::unsubscribe(...) Use of wildcards?

[ThirdStrand]

Wondering if anyone knows off the top of the head:

Like when one is disconnecting slots:

QObject::disconnect(obj, 0, 0, 0);

can one do a :

myClient->unsubscribe(QMqttTopicFilter("#"));

to unsubscribe to all topics on a given broker? And the extension to that question is can one unsubscribe using the wildcards to only unsubscribe to a set of topics?

Well, it appears the topics are held in a QHash and that unsubscribe simply removes that item from the hash. So I guess that answers that!
