Qt 스레드가 오류를 만듭니다

Question

다음 코드 줄을 구축 할 때 이상한 오류가 발생합니다. (나는 QVector와 qthread를 들고있다).

nodeProcess.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];
}

.

누군가 내가 뭘 잘못하고 있는지 아이디어? 어떤 힌트가 나를 도울 것입니다 :).

누군가 내가 뭘 잘못하고 있는지 아이디어?

꽤 몇 가지!

첫째, Qthread를 사용하려는 경우 실제로 QThread가 스레딩을 관리하는 방법을 변경하지 않는 한 실제로 계획하지 않는 한 상속하지 마십시오. qthread는 실제 스레드 자체보다 스레드 컨트롤러가 더 많습니다.

해야 할 일은 클래스를 만들고 Qobject에서 파생 한 다음 그런 다음 새 qthread로 이동하는 것입니다. "는 정말로 qthreads "여기에서 예제 코드를 템플릿으로 사용하십시오.

또한 NodeProcess 인스턴스의 QVector를 생성합니다. 이렇게하면 복사 생성자가 호출되지만 Object는 Qobject에서 파생됩니다. Copy 생성자가 비공개입니다. 그래서이 오류가 발생합니다 : -

오류 : 'qobject :: qobject (const qobject &)'는 비공개

노드 프로세스 포인터의 QVector를 사용해야합니다. QVector 를 사용하여 필요에 따라 할당하십시오.
