Get Source code of QWebEnginePage

[AmrCoder]

when I press left click on any web page in webEngineview I have the option to view the source code for the current page.
that I want to do it programming I want to set this page source code to a QString so I can do what I want with it
I tried both
QWebEnginePage.toHtml() and toPlaintText but both not give me as I found in the left click view page source code from the view
for example, i tried on facebook page toHtml give me codes and the view page source code give me a more detailed code that what I want so any help to get this code to QString
thanks in advance

Hi! Don't know why toHtml() and right-click-view disagree. Maybe you can use the following as a work-around. It gives the exact content of the right-click-view:

ui->webEngineView->setUrl(QUrl("view-source:https://facebook.com"));
// ...
// on load finished:
ui->webEngineView->page()->toPlainText( [this](QString const &s){ ui->plainTextEdit->setPlainText(s); } );
