QDBusConnection how to handle ALL MESSAGES?

MoOr

Hi, I've tried this one:

class DBusListenerVirtualObject : public QDBusVirtualObject
{
// QDBusVirtualObject interface
public:
QString introspect(const QString& path) const Q_DECL_OVERRIDE;
bool handleMessage(const QDBusMessage& message, const QDBusConnection& connection) Q_DECL_OVERRIDE;
};

QString DBusListenerVirtualObject::introspect(const QString& ) const
{
return "";
}

bool DBusListenerVirtualObject::handleMessage(const QDBusMessage& message, const QDBusConnection& )
{
if(message.member() != "Log")
{
qDebug() << message;
}
return true;
}

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

if(QDBusConnection::sessionBus().isConnected()) {
    QDBusConnection bus = QDBusConnection::sessionBus();
    QDBusInterface dbusInterface("org.freedesktop.DBus", "/org/freedesktop/DBus",
                              "org.freedesktop.DBus.Monitoring", bus);

    qDebug() << "Connected to Monitoring interface";

    qDebug() << dbusInterface.call("BecomeMonitor", QStringList(), 0u);

    DBusListenerVirtualObject listener;
    qDebug() << "Object registered:" << bus.registerVirtualObject("/", &listener, QDBusConnection::SubPath);

    return a.exec();
}

return 0;

}

It seems that I recieve MethodCall messages, but I don't receive any signal messages, how can I handle signal messages? What have I missed? Please help me!
