PySide2.QtWebKit not available ?!

[Anonymous]

Enter this code "from PySide2.QtWebKit import QWebView" to VRED 2018.3 (10.11) terminal the result is: 

root: from PySide2.QtWebKit import QWebView

Traceback (most recent call last):

File "<string>", line 1, in <module>

ImportError: No module named QtWebKit

Does that mean pyside2 is  limited and can't deal with QWebView (i.e. to emulate a browser) ??

QtWebkit is deprecated and therefore no longer supported. You should use QWebEngine instead: http://doc.qt.io/qt-5/qtwebenginewidgets-qtwebkitportingguide.html

Hmm??

I'm not sure what you mean with: use QWebEngineView?!

In fact this doesn'r work either:

root: from PySide2.QWebEngine import *

Traceback (most recent call last):

File "<string>", line 1, in <module>

ImportError: No module named QWebEngine

Hi,

it should be

from PySide2.QtWebEngineWidgets import QWebEngineView

For example:

from PySide2.QtWebEngineWidgets import QWebEngineView
from PySide2.QtCore import QUrl

view = QWebEngineView()
view.load(QUrl("https://wiki.qt.io/PySide2"))
view.show()

Kind regards

That's a big progress !!!

But I have still some strange problem:

This code works fine:

# -*- coding: utf-8 -*-
import sys

try: # Version 2018+
   from PySide2.QtWebEngineWidgets import QWebEngineView
   from PySide2.QtCore import QUrl
except ImportError:
   print "Uuups, can't import all needed stuff"

if __name__ == '__main__':
   view = QWebEngineView()
   view.load(QUrl("https://wiki.qt.io/PySide2"))
   view.show()

But the folowing code doesn't show anything !!! ????

# -*- coding: utf-8 -*-
import sys

try: # Version 2018+
   from PySide2.QtWebEngineWidgets import QWebEngineView
   from PySide2.QtCore import QUrl
except ImportError:
   print "Uuups, can't import all needed stuff"

def run():
   view = QWebEngineView()
   view.load(QUrl("https://wiki.qt.io/PySide2"))
   view.show()

if __name__ == '__main__':
   run()

So question: What's wrong with that???

The view object you create in run() goes out of scope at the end of run, so the widget is deleted again and you don't see it.

Move the code from run() into a class:

# -*- coding: utf-8 -*-
import sys

try: # Version 2018+
   from PySide2.QtWebEngineWidgets import QWebEngineView
   from PySide2.QtCore import QUrl
except ImportError:
   print "Uuups, can't import all needed stuff"

class View:
    def __init__(self):
       self.view = QWebEngineView()
       self.view.load(QUrl("https://wiki.qt.io/PySide2"))
       self.view.show()

if __name__ == '__main__':
   view = View()

Kind regards
