it can't run under pyqt5?
Opened this issue · 8 comments
this wrapper work under Qt not for PyQt5, because PyQt5 don't support QtWebEngine , PyQt only support QtWebEngineWidgets. How to fix this?
Hi @dragondjf. I wrote this wrapper to allow the use of WebEngineView inside QML at a time where pyqt5 just didn't support it. I saw something related to it recently on their changelog, but had no time to check. Will try to check it later, probably they are supporting it right now.
When I wrote this, I was using PyQt 5.4-snapshot-837edec02d98 and Qt 5.4 beta, it worked at the time (I was doing some tests with maps on QML). You can take a look on the example on this repository too.
What is your specific problem? It just doesn't work? Do you have any error message? Can you provide a small piece of code with the problem, and describe what you've done to build it?
Hope to get it solved for you, see ya ;)
it work well, we must run initialize() before we can use WebEngineView, to fix this, I wrote DQuickView like this, so it work nice. or you can use Loader to cotroll WebEngineWrapper initialize fininshed before use WebEngineView.
#!/usr/bin/python
import sys
import os
from PyQt5 import QtCore
from PyQt5 import QtGui
from PyQt5 import QtQuick
from PyQt5 import QtQml
class DQuickView(QtQuick.QQuickView):
"""The DQuickView init webengine in PyQt5"""
def __init__(self):
super(DQuickView, self).__init__()
self.initWebengine()
def initWebengine(self):
component = QtQml.QQmlComponent(self.engine())
component.setData('''
import QtQuick 2.4
import WebEngineWrapper 1.0
WebEngineWrapper {
Component.onCompleted: {
initialize()
}
}
''', QtCore.QUrl(''));
item = component.create()
item.setParentItem(self.rootObject())
Oh, I see. Pretty cool man!
As I just needed WebEngineView on the QML side, I had no worries on trying to initialize it direct on python. But your way works, nice!
I need to use WebEngine rendering to an OpenGL surface, tried compiling this, and it doesn't seem to work (Pyhton 3.x Qt 5.7) @dragondjf - can you provide a more complete example of how you get WebEngineView to work under pyqt5 with qml/QuickView? I can't seem to suss out how to do it from your sample - apologies, I am very new to python!
Actually, I think I have everything sorted, but any time I try to run the example, I get:
file:///D:/WebEngineWrapper-master/example/main.qml:4:1: plugin cannot be loaded for module "WebEngineWrapper": Cannot load library D:\WebEngineWrapper-master\build\WebEngineWrapper\webenginewrapper.dll: The specified module could not be found.
import WebEngineWrapper 1.0
^
Though, 100% the file IS there. QML2_IMPORT_PATH is set properly (changing it causes other issues so I know its being read) any ideas on why it might not be able to see the wrapper code? This is, obviously, on Windows
Hi, I can't test it with Qt 5.7 right now, but it's working on 5.6.2 (python 2.7 and 3.5, on OSX), and PyQt5.6.
Seems there is some problem with PyQt 5.7: https://www.riverbankcomputing.com/pipermail/pyqt/2016-October/038231.html

Got some info from the PyQt guys that say WebEngine should be sorted out in the next release of PyQt that's due in a few weeks. I suppose I'll just wait it out and see if that really does correct things. Thanks for the response!
Hello!
Loading WebEngine from QML produces segfault. I am using Qt 5.8.
In C++ code, everything works fine; I think the reason is that in C++ there is "QtWebEngine::initialize()".
Is there still no way to use WebEngine with PyQt without wrappers?
