qt5 python ide_#564 (run eric6 python ide along with qgis3/qt5 error) – OSGeo4W

Thank you jef,

now i have QtWebEngineProcess?.exe, it's in my path, but python/Qt doesn't find it. So it's quite the same.

I do use this little python script for further testing. It tries to show a QWebEngineView.

import sys

from PyQt5.QtWidgets import QApplication

from PyQt5.QtWidgets import QMainWindow

from PyQt5.QtWebEngineWidgets import QWebEngineView

from PyQt5.QtCore import QUrl

def main():

app = QApplication(sys.argv)

window = QMainWindow()

window.setWindowTitle('PyQt Demo')

window.setGeometry(320, 180, 960, 540)

view = QWebEngineView()

view.load(QUrl('http://leafletjs.com/')) # error here

window.setCentralWidget(view)

window.show()

sys.exit(app.exec_())

if __name__ == '__main__':

main()

QT_PLUGIN_PATH ist set. When I also set QTWEBENGINEPROCESS_PATH to the correct path, the error isn't showing - but then i got new ones:

It seems, qt has a wrong configuration, icudtl.dat is in G:tmpq3appsQt5resources, qtwebengine_locales is under G:tmpq3appsQt5translations. I used py3_env.bat and qt5_env.bat before execution.

My path:

PATH=G:tmpq3appsqt5bin;G:tmpq3appsPython36;G:tmpq3appsPython36Scripts;G:tmpq3appsqt5bin;G:tmpq3bin;C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSsystem32WBem;G:tmpq3appsPython36Scripts;G:tmpq3appsqgisbin

Some entries are doubled, as you can see...
