Los hilos QT hacen error

Question

Estoy obteniendo algunos errores extraños al crear las siguientes líneas de código: (Estoy incluyendo qvector y qthread).

NOODPROCESS.H:

class NodeProcess : public QThread
{       public:
        NodeProcess();

        unsigned int create_NewProcess(int priority);
        NodeProcess operator[](int relativeID); private:
        int priority;
        unsigned int ID;
        unsigned int threadCount;

        QVector<NodeProcess> mProcess; 

};

nodeprocess.cpp:

NodeProcess::NodeProcess()
{
    threadCount = 0;
}

unsigned int NodeProcess::create_NewProcess(int priority){
    this->priority = priority;

    threadCount++;
    NodeProcess newProcess;
    mProcess.append(newProcess);
    return threadCount;
}

NodeProcess NodeProcess::operator[](int relativeID)
{
    return mProcess[relativeID];
}

Alguien ¿Alguna idea de lo que estoy haciendo mal? Cualquier sugerencia me ayudaría :).

¡Mantuas cosas!

En primer lugar, si vas a usar QThread, no lo hubiera heredado, a menos que esté planeando cambiar cómo QThread logra enhebrar. QThread es más un controlador de hilo que el enredadero real.

Lo que necesita hacer es crear su clase y derivar de QOBJECT, luego muévase a un nuevo QThread. Puede leer sobre cómo " Realmente realmente use qthreads "aquí y use el código de ejemplo como plantilla.

También estás creando un QVector de instancias de nodoProcesado. Esto invoca al constructor de copia, pero el objeto se deriva de QOBJECT, cuyo constructor de copia es privado. Es por eso que obtienes este error: -

ERROR: 'QOBJECT :: QOBJECT (Const QOBJJECT &)' es privado

Debe usar un QVector de punteros de proceso de nodo: qvector y asignarlos según sea necesario.
