PyQt5 QWebEngineView does not show webpage

[colin.mcphail at mac.com]

Hi Jean-Baptiste,

I think that you need to create and execute an application object in order to keep the QWebEngineView on screen:
insert the line  app = QtWidgets.QApplication( [] )  before the  dlg = ...  line
add the line     app.exec_()  at the end of your example

Hope this helps.
