QtWebEngine : Load URL with HTTPPost

[subzero255]

I'm porting an internal browser from QtWebKit to QtWebEngine.

I want a function to request url while posting some data.
With WebKit, I could use the following:

With class WebView derived from QtWebView :

void WebView::loadPostUrl(const QUrl &url, QByteArray postdata)
{
	m_initialUrl = url;
	QNetworkRequest request = QNetworkRequest(url);
	request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");
	load(request, QNetworkAccessManager::PostOperation, postdata);
}

Since QtWebEngine does interact with QNetworkAccessManager how can we have the same functionalities with QtWebEngine ?

Thanks
