如何在QThread和QGui之间传递参数？

class MyThread : public QThread
{
    Q_OBJECT

signals:
    void resultReady(const QString& result);

protected:
    void run() override {
        // 执行耗时任务
        QString result = "Hello from background thread!";
        
        // 发送信号
        emit resultReady(result);
    }
};

class MyGuiClass : public QObject
{
    Q_OBJECT

public slots:
    void handleResult(const QString& result) {
        // 处理接收到的参数
        qDebug() << "Received result: " << result;
    }
};

// 创建对象并连接信号和槽
MyGuiClass guiObject;
MyThread threadObject;

QObject::connect(&threadObject, &MyThread::resultReady, &guiObject, &MyGuiClass::handleResult);

threadObject.start();
