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

    Your MyThread instance is in a different thread than the "socket" instance it contains but you are calling the socket's write method without any thread change.

    Could you please tell me how?
    I tried using movetothread() and changing my signals&slots but I could not figure it out...

    You could send the data to an object that lives in the second thread, e.g. connecting a signal of MyThread to a slot of such an object and emitting that from MyThread::writeData() or calling that slot via QMetaObject::invokeMethod.

    Alternatively you could split MyThread into a normal QObject subclass that provides the API you connect to and move that into a plain QThread instance.

    Alternatively you could try thread->moveToThread(thread) and not pass "this" to the MyThread constructor
