The returned proxy method can be called in the usual way. For instance, :: proxy.get_dbus_method("Foo", dbus_interface='com.example.Bar')(123) is equivalent to:: proxy.Foo(123, dbus_interface='com.example.Bar') or even:: getattr(proxy, "Foo")(123, dbus_interface='com.example.Bar') However, using `get_dbus_method` is the only way to call D-Bus methods with certain awkward names - if the author of a service implements a method called ``connect_to_signal`` or even ``__getattr__``, you'll need to use `get_dbus_method` to call them.
