Error: incompatible type of argument(s) in call to call(); candidates were call(QString,QJsonValue)

Specification

• Platform:raspberry pi arm64 ubuntu
• Version: pywebview-2.2.1 python3

Description

first,I according to the doc, apt isntall qt5-default apt install python3-pyqt5 python3-pyqt5.qtwebkit libqt5webkit5-dev

but i cant run test,I found the pyqts version is 5.5.1， and debug found can`t import QtWebEngineWidgets,so I edit version check in qt.py of source,I try import from PyQt5 import QtWebKitWidgets and it works.

then,I try examples for https://pywebview.flowrl.com/examples/js_api.html click “Hello Python” button nothing happen,so i try catch the function pywebview.api.init().then(showResponse)

I got: Error: incompatible type of argument(s) in call to call(); candidates were call(QString,QJsonValue)

I refactored the code, so that it determines at the import stage whether WebEngine is available and sets a flag accordingly or not and the rest of conditionals are based on that flag. Version check is completely gone. In addition to installations instructions, WebEngine Travis builds need to be figured out as well. Travis provides Ubuntu Xenial at best, which comes with QT5.5.

@r0x0r It is works on ubuntu16 used qt-5.5.1,at the same time,I did test on ubuntu18 used qt-5.10,it is not works,so I viewed the qt.py source code,I think it is not good what import QtWebkit or QtWebEngineWidgets by qt`s version, QtWebEngineWidgets and QtWebkit is Two different components,so use QtWebEngineWidgets need apt install python3-pyqt5.qtwebengine python3-pyqt5.qtwebchannel and use QtWebkit apt install python3-pyqt5.qtwebkit.They have nothing to do with versions.Just QtWebEngineWidgets provide since qt5.6
