    After updating qt creator, i have a warning on this :

        QByteArray buffer;
        buffer.resize(socket->pendingDatagramSize());    
    

    warning : implicit conversion loses integer precision : 'qing64' (aka 'lonl long') to int

    can i just do static_cast<int>() or is there a better solution ?

      You can safely do a static_cast<int> here since the pendingDatagramSize will never exceed 2GB (in the near future)
