how to read out the values of a complex dbus reply

Hi, I am trying to understand how I could read out the values of a complex dbus reply I want to access following // org.freedesktop.DBus.ObjectManager.GetManagedObjects (out DICT<OBJPATH,DICT<STRING,DICT<STRING,VARIANT>>> objpath_interfaces_and_properties); https://dbus.freedesktop.org/doc/dbus-specification.html#standard-interface… In my code I do TQT_DBusConnection connection = TQT_DBusConnection::systemBus(); if (!connection.isConnected()) tqFatal("Failed to connect to system bus"); TQT_DBusProxy proxy(connection); proxy.setService("org.bluez"); // who we work with proxy.setPath("/"); // which object inside the peer work with proxy.setInterface("org.freedesktop.DBus.ObjectManager"); if ( connection.isConnected() ) { if ( proxy.canSend() ) { TQValueList<TQT_DBusData> params; TQT_DBusMessage reply = proxy.sendWithReply("GetManagedObjects", params ); if ( reply.type() != 2 || reply.count() != 1 || reply[0].type() != TQT_DBusData::Map) tqFatal("GetManagedObjects failed"); kdDebug() << "TQT_DBusMessage: Reply " << reply.type() << endl; kdDebug() << "Type: TQT_DBusDataMap " << reply[0].type() << endl; kdDebug() << "Count : " << dict.count() << endl; TQT_DBusDataMap<TQT_DBusObjectPath> dict( reply[0] ); for (TQT_DBusDataMap<TQT_DBusObjectPath>::const_iterator it = dict.begin(); it != dict.end(); ++it) { kdDebug() << (*it).type() << endl; } } else tqFatal("proxy can not send messages"); } else tqFatal("manager is not connected"); result is ./bttest TQT_DBusMessage: Reply 2 Type: TQT_DBusDataMap 16 Count : 0 but when I run gdbus call -y -d "org.bluez" -o "/" -m "org.freedesktop.DBus.ObjectManager.GetManagedObjects" ({objectpath '/org/bluez': {'org.freedesktop.DBus.Introspectable': @a{sv} {}, 'org.bluez.AgentManager1': {}, 'org.bluez.ProfileManager1': {}, 'org.bluez.Alert1': {}, 'org.bluez.HealthManager1': {}}},)
