[QTcpSocket] Cannot create children for a parent that is in a different thread

[amleto]

eewww, why are you pasing QString by reference for logging calls? Not even const reference! QString should definitely be passed by value.

If you slot doesn't get hit, first thing you should do is debug the connections - does qt give any error message? Then debug what happens after the signal.

Well, I think I found the issue. Passing QString by reference may be something that wasn't intended, but technically it works (slot will be invoked). I think, the problem is you emit signals before establishing connection.

PollController *pollController = new PollController();
 
    // you emit signals here !
    pollController->setup(1,1000);
 
    Analyzer *analyzer = pollController->getAnalyzer();
 
 
 
    QThread pollThread;
 
    pollController->moveToThread(&pollThread);
 
 
 
    Logger *logger = new Logger();
    // you establish connection here! doesn't even get called
    logger->setup(host,port,analyzer);

PollController *pollController = new PollController();

    // you emit signals here !
    pollController->setup(1,1000);

    Analyzer *analyzer = pollController->getAnalyzer();

 

    QThread pollThread;

    pollController->moveToThread(&pollThread);

 

    Logger *logger = new Logger();
    // you establish connection here! doesn't even get called
    logger->setup(host,port,analyzer);

However, it seems to not have any relation to my post. G00d luck.
