如何从多个std：：线程手动发送QSignal？

#include <QObject>
#include <QThread>
#include <QDebug>

class MyObject : public QObject
{
    Q_OBJECT
public slots:
    void handleSignal()
    {
        qDebug() << "Signal received in thread: " << QThread::currentThreadId();
    }
};

int main()
{
    QThread thread1;
    QThread thread2;

    MyObject receiver;

    // 在多个std::线程中创建QSignal对象和对应的槽函数
    QSignal signal1;
    QSignal signal2;

    // 将信号与槽函数连接起来
    QObject::connect(&signal1, &QSignal::signal, &receiver, &MyObject::handleSignal);
    QObject::connect(&signal2, &QSignal::signal, &receiver, &MyObject::handleSignal);

    // 在多个std::线程中发送信号
    thread1.start();
    thread2.start();

    signal1.emit(); // 发送信号1
    signal2.emit(); // 发送信号2

    thread1.wait();
    thread2.wait();

    return 0;
}
