Correspondence between dbus-send and QDBusAbstractInterface

Question

What is the correspondence between parameters of dbus-send utitily and parameters of constructor and call* methods of QDBusAbstractInterface?

There is a plenty of examples (e.g. [1]) in the Internet of how to rule NetworkManager via DBus using dbus-send utility, but I can't infer how to transform them into Qt C++ code.

Answer 1

The question sounds a little too generic for any answer to be very useful for you but...

dbus-send --dest=com.example.service \
          /service/path \
          com.example.interfacename.Method \
          int32:123

should match

QDBusInterface iface("com.example.Service",
                     "/service/path",
                     "com.example.interfacename");
iface.call("Method", 123);
