[Interest] qml <--> c++

[Nicolas Jäger]

Hi Tony,
yesterday when I compiled with Q_OBJECT I got error, but today it works, I have no idea why...but
yes I agree I should have Q_OBJECT. But this doesn't solve my problem. Also I guess I can rewrite a
new class who inherits of QWebEngineView with all Q_PROPERTY and stuff to make it works as I want,
but since we are talking about C++ I expecting to be able to inherits the QML code associated to the
class (QWebEngineView), instead of rewrittng all QML code (for that class) from scratch.

regards,
Nicolas
