Closing QWebEngineView (QtWebEngineProcess.exe)

[Kasea]

Seems like i found the culprite. It would seem that deleting the QWebEngineView wasn't enough, because the QWebEngineView generates a QWebEnginePage.

I would assume that closing the view would close the page aswell, but wouldn't seem so... The fix was to get the page (or initlize as a page) and close that then the view.

I've been running this for about 40 minutes now without any problems.

Scratch that, it broke, however it does seem more stable now.

Migrating from Qt5.7 to Qt5.12 and from MSVC2015 to MSVC2017 we ran into a similar situation, where QWebEngineProcess.exes would stay open after our application closed. It turned out, we did not properly specify the parent for our custom page for it to be autodeleted with the view on destruction! Hope this helps someone to avoid some debugging :-)
