This is first quick port to QtWebEngine, most of advanced features
are not working yet. Please read README.
For now, it will use separate profile directory as well as browser
session, that means you can use both QtWebEngine and QtWebKit versions
at the same time.
- when leaving web widget, QWebPagePrivate generates fake
mouse move event, but unfortunately with bad coordinates.
So sometimes it just hovered a link and the link's url got
stuck in status bar message.
- plugins can now register scheme handlers
- tweaked javascript alert window
- initial support for Geolocation & Notifications API
* question to ask user for permission needs not implemented yet
