如何将QEvents传递给子小部件？

class ParentWidget : public QWidget
{
    Q_OBJECT

signals:
    void customEventTriggered(QEvent* event);

public:
    void sendCustomEvent()
    {
        QEvent* customEvent = new QEvent(QEvent::User);
        emit customEventTriggered(customEvent);
    }
};

class ChildWidget : public QWidget
{
    Q_OBJECT

public slots:
    void handleCustomEvent(QEvent* event)
    {
        // 处理自定义事件
    }
};

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

    ParentWidget parent;
    ChildWidget child;

    QObject::connect(&parent, &ParentWidget::customEventTriggered, &child, &ChildWidget::handleCustomEvent);

    parent.sendCustomEvent();

    return app.exec();
}
