thanks for all your work on this Reinhard. i will try to find time to do 
a pull and test all your fixes when Edward has committed them to git.

I'm afraid, it's not that easy. We need some more  assignments (in red):

try:
from PyQt5 import QtWebKit
except ImportError:
# 2016/07/13: Reinhard: Support pyqt 5.6...
try:

from PyQt5 import QtWebEngineCore as QtWebKit
except ImportError:

QtWebWidgets.QWebSettings = QtWebWidgets.QWebEngineSettings

except ImportError:

thanks Edward.  ;)   i will test this, with pyqt 5.6  when i get a 
chance tomorrow arvo.


my only concern was whether full compatibility for whatever api 
functions you are using from QtWebKit is retained
in the QTWebEngine code that replaces it from pyqt 5.6 onward. hopefully 
the nice qt and pyqt folk have been kind.

Rev 582fe79 attempts a fix.  The only significant change is the following:

​try:
from PyQt5 import QtWebKit
except ImportError:
# 2016/07/13: Reinhard: Support pyqt 5.6...
try:
from PyQt5 import QtWebEngineCore as QtWebKit
except ImportError:
QtWebKit = None
try:
import PyQt5.QtWebKitWidgets as QtWebKitWidgets
except ImportError:
try:
# 2016/07/13: Reinhard: Support pyqt 5.6...
import PyQt5.QtWebEngineWidgets as QtWebKitWidgets
QtWebKitWidgets.QWebView = QtWebKitWidgets.QWebEngineView
except ImportError:
QtWebKitWidgets = None​

Some notes:

1. QtWebKit is used only in the richtext plugin, so the assignment QtWebKit
= None is unlikely to be involved directly.  However, I see no reason not
to change the code as shown above.

2. In general, we want to retain existing imports to ensure backward
compatibility.  For this reason, the new imports, namely:

import PyQt5.QtWebEngineWidgets as QtWebKitWidgets
QtWebKitWidgets.QWebView = QtWebKitWidgets.QWebEngineView


are tried only if this fails:

import PyQt5.QtWebKitWidgets as QtWebKitWidgets

I have not tested this in detail, and certainly not with pyqt 5.6.  Please
report any problems.

yes, this would work if the interface to and behaviour of

the renderer needs to be fixed to support QtWebEngine, as john lunzer

Well, I don't know, if it this is being fixed, but I know, how this 
can be fixed:

In leoQt.py outcomment and insert the following lines:

 ...
try:
# from PyQt5 import QtWebKit
from PyQt5 import QtWebEngineCore as QtWebKit
except ImportError:
QtWebKit = None
try:
#import PyQt5.QtWebKitWidgets as QtWebKitWidgets
import PyQt5.QtWebEngineWidgets as QtWebKitWidgets
QtWebKitWidgets.QWebView = QtWebKitWidgets.QWebEngineView
except ImportError:

...

At least, this allows me to show the viewrendered pane. If there are 
other implications, I don't know.

Re: can not load enabled plugin: viewrendered3 bigdash

[Sami J]

Hi all,
I tried to post a comment in this thread earlier today but since I don't 
see it published maybe something went wrong, so I do it again just in case.

In short, it seems that QtWebKit and QtWebKitWidgets are not being 
installed for PyQt5 anymore on Windows since they have been deprecated and 
removed upstream in Qt version 5.6.

QtWebKit/QtWebKitWidgets have apparently been replaced by 
QtWebEngine/QtWebEngineWidgets, which are indeed installed on Windows using 
the current PyQt5 binaries.

This means that Leo users on Windows/PyQt 5.6 cannot use the viewrendered 
plugins if this relies on QtWebKitWidgets.

Perhaps the plugin can be updated to use QtWebEngine/QtWebEngineWidgets 
instead?

Re: can not load enabled plugin: viewrendered3 bigdash

[Sami J]

Lewis,
I had the same issue and I noticed that QtWebKit and QtWebKitWidgets had 
not been installed at all by the current Windows installers for PyQt5 5.6.0.
They are not even packaged in these installers.

I followed this up on the *PyQt* 
 mailing list and 
I was told that QtWebKit had been deprecated upstream in Qt 5.5 and removed 
in 5.6,
so presumably that's why is not available in the PyQt5  Windows installers 
anymore.
I assume this also applies to QtWebKitWidgets.

If so, this is an issue for all users of the viewrendered plugin who are 
using PyQt5 version 5.6.0 on Windows.
Perhaps viewrendered should be updated to use QtWebEngine (including 
QtWebEngineWidgets), which is replacing QtWebKit?

Any thoughts?

[john lunzer]

Lewis, it doesn't seem too likely that is related. QtWebEngine is a 
different web platform based on Chromium (versus WebKit). So the two are 
likely unrelated, QtWebEngine was added after QtWebEngine.

Hi Edward,

I didn't found anything specific about QtWebKitWidgets installation 
problems, but this issue on the Spyder-IDE site is possibly 
relevant: https://github.com/spyder-ide/spyder/issues/3073

Also this from the PyQt5 5.6.1.dev changelog:
'changeset: 06ecf8131050

date:Mon Apr 25 09:33:33 2016 +0100 

Fixed the Windows installers so that QtWebEngineProcess works.'

QtWebKitWidgets does not seem available. This looks like an installation
problem. You might try googling ​PyQt5.QtWebKitWidgets for more info.

​I just checked that viewrendered3.py uses the proper way to get access to
Qt:

from leo.core.leoQt import phonon, QtSvg, QtWebKitWidgets, QUrl​


​It's possible that PyQt5 uses different imports than PyQt4 for ​
​​
QtWebkitWidgets, and that might make leo.core.leoQt return None for ​
​​
QtWebkitWidgets. The relevant code inside leoQt is:

try:
import PyQt5.QtWebKitWidgets as QtWebKitWidgets
except ImportError:
QtWebKitWidgets = None

Please try the following in a test .py file (or within Leo) and report the
results:

import PyQt5.QtWebKitWidgets as QtWebKitWidgets

The PyQt5 docs http://pyqt.sourceforge.net/Docs/PyQt5/introduction.html# 
 state 'PyQt5 comprises a number of different components. First of all 
there are a number of Python extension modules. These are all installed in 
the PyQt5 
 
Python package.' and QtWebkitWidgets is included in the list.

As you can see from the log I have both python 3.5.1 and PyQt5 so it should 
be installed. I reinstalled to make sure I hadn't missed any option but no 
change.
Has anyone had a similar issue?

Regards
Lewis

​Presumably, you must install QtWebKitWidgets​
 separately.​
