QWebEngineView 无法获取鼠标事件QMouseEvent

最近有个需求，需要在QWebEngineView加载网页后模拟一个点击，直接创建一个QMouseEvent同过QApplication::sendEvent或者QApplication::postEvent发送给QWebEngineView,发现QWebEngineView中没有执行QWebEngineView::mousePressEvent和QWebEngineView::mouseReleaseEvent,通过查找资料，发现QWebEngineView在加载界面后，被本身的child接收了改事件

解决办法：同过重载event，截取QEvent::ChildAdded事件，通过智能指针QPointer保存这个child指针（类型QOpenGLWidget），我们可以通过send鼠标信号到这个child即可模拟正常的鼠标点击事件

bool CWebEngineView::event(QEvent *event)
{
    if(event->type() == QEvent::ChildAdded)
    {
        QChildEvent* childEvent = (QChildEvent*)event;
        if(childEvent)
        {
            QObject *child = childEvent->child();
            qDebug()<<"className"<metaObject()->className();
            QOpenGLWidget *w = qobject_cast(child);
            if (w)
            {
                //do something
                qDebug()<<"w className"<metaObject()->className();
            }
        }
    }
    return QWebEngineView::event(event);
}
