如何在Qt中从循环中独立运行的子线程中调用父线程函数

class Worker : public QObject
{
    Q_OBJECT

public:
    explicit Worker(QObject *parent = nullptr);

signals:
    void resultReady(int result);

public slots:
    void doWork();
};

void Worker::doWork()
{
    // 执行子线程任务
    int result = 0;
    // ...

    // 发送结果给父线程
    emit resultReady(result);
}

QThread* thread = new QThread;
Worker* worker = new Worker;

worker->moveToThread(thread);

QObject::connect(worker, &Worker::resultReady, [thread, worker](int result){
    // 在父线程中处理结果
    // ...

    // 任务完成后退出子线程
    worker->deleteLater();
    thread->quit();
});

QObject::connect(thread, &QThread::started, worker, &Worker::doWork);
thread->start();
