As I understand adaptors and interfaces classes is gates from Qt to
dbus. But they seem unidirection.
It's right? Or i'm wrong?

for example at now I catch signals in following way:

MainClass::MainClass(const QDBusConnection & _connection_)
:   connection(_connection_)
{
    // add our D-Bus interface and connect to D-Bus
    new Sim300Adaptor(this);
    connection.registerObject("/", this);

    connection.connect(QString(), QString(), "com.i_zum.sim300",
"send_data",      this, SLOT(countersSlot(QByteArray)));
    connection.connect(QString(), QString(), "com.i_zum.sim300",
"get_money_atd",  this, SLOT(get_money_atd()));
    connection.connect(QString(), QString(), "com.i_zum.sim300",
"get_money_cusd", this, SLOT(get_money_cusd()));
    connection.connect(QString(), QString(), "com.i_zum.sim300",
"get_csq",        this, SLOT(get_csq()));
    connection.connect(QString(), QString(), "com.i_zum.sim300",
"get_opers_list", this, SLOT(get_opers_list()));
    connection.connect(QString(), QString(), "com.i_zum.sim300",
"set_oper",       this, SLOT(set_oper(QString)));
}

but at now I'm interesting in more transparent or more abstracted way

Hm, May be I'm wrong than adaptors is for service and interfaces for
clients and both require both of them?
