QtWebEngine

Hi and welcome to devnet, That's a question you should bring to the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

@mousemao I've made a feature request here https://bugreports.qt.io/browse/QTBUG-55074 BTW, 大哥，你好~~

Ok this put me in the right direction, having subclassed both the view and page, and using createWindow and acceptNavigationRequest, I see how this all works now.. Thanks!

Your code works seamlessly for normal YouTube videos. Live video streams still have the flicker effect. Thanks for your time

The solution was simple, i was inattentive, but Web Engine Team helps me, thanks guys webView.onNavigationRequested: { if(request.navigationType === WebEngineView.BackForwardNavigation) { print("onNavigationRequested", request.url) request.action = WebEngineView.IgnoreRequest; } }

Thanks for the pointer, @Andriy, although I must confess that I have given up on Qt WebEngine. No matter what the Qt guys may say, it's not, in my opinion, ready to replace Qt WebKit, as confirmed by QTBUG-52999 indeed (this won't be fixed before 5.8!), as well as the fact that they still ship the source code for Qt WebKit (and, from what I have seen, correct a few things here and there in Qt WebKit) and that the help in Qt Creator (which I understand now uses Qt WebEngine) doesn't render well anymore, etc.

Ok. Thanks for all.

For anyone interested, I solved the problem. None of the qtwebengine projects will run outside of QtCreator unless you run macdeployqt on the package first. But in order to get macdeployqt to work you need to specify the path to the Qml root directory of your project. macdeployqt path/to/quicknanobrowser.app -qmldir=./path/to/my/quicknanobrowser/root
