如何从QThread发出2个类的相同信号

class ClassA : public QObject
{
    Q_OBJECT

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

signals:
    void signalA();
};

class ClassB : public QObject
{
    Q_OBJECT

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

signals:
    void signalA();
};

class MyThread : public QThread
{
    Q_OBJECT

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

protected:
    void run() override;

private:
    ClassA *classA;
    ClassB *classB;

private slots:
    void handleSignalA();
};

MyThread::MyThread(QObject *parent)
    : QThread(parent)
{
    classA = new ClassA();
    classB = new ClassB();

    connect(classA, &ClassA::signalA, this, &MyThread::handleSignalA);
    connect(classB, &ClassB::signalA, this, &MyThread::handleSignalA);
}

void MyThread::run()
{
    // 在这里执行线程的逻辑
    // ...

    // 发出信号
    classA->signalA();
    classB->signalA();
}

void MyThread::handleSignalA()
{
    // 处理信号A的槽函数
    // ...
}

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    MyThread thread;
    thread.start();

    return a.exec();
}
