QT widget used in the card editor

Hi,
I’m not much familiar with anki code base, where’s in the code the QT widget displaying the html?

Is it a standard QT QTextEdit widget?

I’m working on the syntax_highlighting_ng addon, and I need to be able to quickly test the changes.
Thanks

It’s QWebEngineView. Here’s an example: PyQt QWebEngineView - working with QWebEngineView in PyQt

Thanks!
