[QGIS-Developer] Qt WebEngine in QGIS 3.36

[Enzo Cocca]

Hi Enrico, have you tried to import early the qwebengine before the other
modules?

Like that example:

from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEnginePage
from qgis.PyQt.QtCore import QCoreApplication, QObject
from qgis.PyQt.QtWidgets import QAction
from qgis.core import QgsApplication
from qgis.gui import QgsMapCanvas

class MyPlugin(QObject):
    def __init__(self, iface):
        super().__init__()
        self.iface = iface
        self.web_view = QWebEngineView()
        self.web_view.setPage(QWebEnginePage())
        self.initGui()

I fixed the same problem in this way but I use windows not Linux

Best
E
