Sorry, I meant "DBusInterface", that's the class name your C++ code,
which you rename to ActivityJumper in the qmlRegisterType statement.
(Might I suggest a less general, more meaningful name for
DBusInterface?)

Yes, you need to use that import whenever you use your objects /
classes defined within the scope of that import.
Connection works as well, but it's way clearer to put the signal
handler within the object that defines it, keeps code nicely grouped
and reduces the creation of an unnecessary Connection object.
