Problem with PySide6 and QtWebEngineWidgets module
-
Hi!
I recently installed PySide6 on my Linux machine, I needed a more than valid reason to finally "ditch" Python 2.7. In particular, I'm interested in handling Web content and then working with QtWebEngineWidgets.
Up to now each time I have tried to import such module I get back a "ModuleNotFoundError: No module named 'PySide6.QtWebEngineWidgets" error.
I document myself but I was not able to find a solution... just more confusion! Here some results of my investigations.From the description of the official pages it is not clear to me if QtWebEngine is installed by default:
- the availability and compatibility of Qt Web Engine with my PC is guaranteed by https://www.qt.io/product/features but it appears as "Framework Add-Ons". Does this mean that it has to be installed separately? How do I do that?
- From this page https://doc.qt.io/qtforpython-6/api.html it seems that QtWebEngineWidgets is taken for granted, but in the complete list it does not appear at all https://doc.qt.io/qtforpython-6/modules.html and in here also https://doc.qt.io/qt-6/qtmodules.html.
- I also found in the (Linux) folder with the examples '~/.local/lib/python3.8/site-packages/PySide6/examples/webenginewidgets/' but the compiler gives me an error when running one of them [see remark]. For instance just the line
from PySide6.QtWebEngineWidgets import QWebEnginePage, QWebEngineView
return me a module not found error.
Where do you find QtWebEngineWidgets and/or how do you install it? I have no idea on how to move forward... I would appreciate any kind of advice.
Thanks in advance
Remark:
# fully upgraded Linux machine
# I installad PySide6 via pip:
pip3 install PySide6
# check version (and also with some "Hallo world"-type applications)
python -c "import PySide6; from PySide6 import QtCore; print(PySide6.__version__, PySide6.QtCore.__version__)"
6.0.0 6.0.0
# import QWebEngineView
python -c "import PySide6; from PySide6 import QtWebEngineWidgets;"
ImportError: cannot import name 'QtWebEngineWidgets' from 'PySide6' (~/.local/lib/python3.8/site-packages/PySide6/__init__.py)
or

ModuleNotFoundError: No module named 'PySide6.QtWebEngineWidgets'

So if you want to use QtWebEngine then you must still use PySide2.

Hi eyllanesc!
Thanks for your quick reply! It is with great sadness that I read your reply... Qt6.2 will be released this September/October.
By the way do you know any PySide2 doc/manual web-pages? (official and not) I have had great difficulty to find some good material to start with.
Thanks in advance

If we need wait for Pyside6.2 then why examples exist that use this?
