How to properly connect Slots and Signals over QDBus

RyonMS

So I have a service that will have multiple clients connecting to it. I want to connect a signal to a slot in such a way that when one client emits a signal, all of the other connected clients will also receive this signal. The client objects are subclassed from the auto-generated proxy that shares the same methods and signals as the server class. I'm assuming inside the client class I will have to connect the signals and slots through a QDBusConnection, but I am unsure of how to do this. If anyone could offer some advice I would greatly appreciate it!

The Server Object:

namespace SmartAppMgr
{
    class SmartAppManager : public QObject
    {
        Q_OBJECT

    public:
        SmartAppManager
            (
            QObject* a_parent = NULL
            );

        virtual ~SmartAppManager();

        Q_SIGNAL void PhoneCallStatusChanged( );

        Q_SLOT void onPhoneCallStatusChanged();

        bool getPhoneCallStatus();

        void setPhoneCallStatus( bool status );

    private:
        bool m_phoneCallStatus;
        QDBusConnection mDBusConnection;
    };
}

The Client Object:

namespace SmartAppMgr
{
    class SmartAppManagerClient: public ComSmartAppManagerInterface
    {
        Q_OBJECT

    public:
        //! Constructor
        SmartAppManagerClient
            (
            QDBusConnection const& a_connection, 
            QObject* a_parent = 0 
            );

        //! Destructor
        virtual ~SmartAppManagerClient();
    };
}

The service that actually runs everything:

int main
    (
    int argc,
    char* argv[]
    )
{
    // Creating the app
    QCoreApplication app( argc, argv );
    QDBusConnection connection = QDBusConnection::systemBus();

    SmartAppMgr::SmartAppManager smartAppManager;
    SmartAppManagerAdaptor smartAppManagerAdaptor( &smartAppManager );

    if( connection.registerService( SmartAppMgr::sSmartAppManagerBusName ) )
    {
        qDebug() << "\n\nSuccessfully registered the SmartAppManager DBus Service!\n\n";
    }
    else
    {
        qDebug() << "\n\nFailed to register the SmartAppManager DBus serivce!\n\n";
        return -1;
    }

    if ( connection.registerObject( SmartAppMgr::sSmartAppManagerObjectPath, &smartAppManager ) )
    {
        qDebug() << "\n\nSuccessfully registered SmartAppManager DBus object!\n\n";
    }
    else
    {
        qDebug() << "\n\nFailed to register the SmartAppManager DBus object!\n\n";
        return -1;
    }

    return app.exec();
}

Hi,

Aren't you implementing something like QtRemoteObjects ?
