I played a little bit with JavaScript and QWebChannel but I can't get it to
work (I'm not familiar with JavaScript) which means that I tried to figure out
which frame is created and trigger a signal from within JavaScript.
i think the parsing stuff is easier with regex in c++.
Could someone please help me to handle iframes correctly with QWebEngine.
I think those guys who has desired to replace QWebKit with QWebEngine should
see the problem.
Thanks in advance
