I'v read the documentation for QObject::connect (for Qt 5.4), but I have a question about the overload
QMetaObject::Connection QObject::connect(const QObject * sender, PointerToMemberFunction signal, const QObject * context, Functor functor, Qt::ConnectionType type = Qt::AutoConnection)
What exactly is the context
parameter? What is its purpose? Can it be used to build connections in local event loops in threads?
Can someone provide examples of how/when to use this overload (when the context is not this
)?
