OpenLayers Geolocation in PyQt 5.9

Question

I\'ve implemented a Website with a geolocation function and Button.

This Webpage gets displayed fine in a QwebEngineView (OSM Map too). The Webpage is loaded

Answer 1

Adding the following lines solved my Problems:

    self.ui.w3View.page().featurePermissionRequested.connect(self.permissionRequested)

def permissionRequested(self, frame, feature):
    self.ui.w3View.page().setFeaturePermission(frame, feature, QtWebEngineWidgets.QWebEnginePage.PermissionGrantedByUser)

Found it in this post and editing it to PyQt 5.9.

Answer 2

The main problem is to enable the permissions, if you run in a browser like Firefox, Chrome, etc. will show you a popup asking you to accept or not the GeoLocation permission.

In this case it must be enabled by code, for this the QWebEnginePage emits a signal every time authorization is required, it does this through the signal featurePermissionRequested, we connect it to some slot and we enable the permission with the function setFeaturePermission().

    self.ui.w3View..page().featurePermissionRequested.connect(self.onFeaturePermissionRequested)

def onFeaturePermissionRequested(self, securityOrigin, feature):
    self.sender().setFeaturePermission(securityOrigin,
                                     QWebEnginePage.Geolocation,
                                     QWebEnginePage.PermissionGrantedByUser)

Note: In linux I still have problems with the GeoClude provider, the error message is as follows:

Failed to set Geoclue positioning requirements. Geoclue error: org.qtproject.QtDBus.Error.InvalidObjectPath
