Hi Alessandro, Yes, we know that (see the second code in previous mail ): the QgsNetworkAccessManager works perfeclty in python, this is not the point. The point is: trying to instanciate a wmsprovider will issue a timeout when trying to request the capabilities: the code responsible for that creates its own QEventLoop and manage to do a blocking call (which is expected here). Please have a look at https://github.com/qgis/QGIS/blob/master/src/providers/wms/qgswmscapabilities.cpp#L1964 <https://github.com/qgis/QGIS/blob/master/src/providers/wms/qgswmscapabilities.cpp#L1964>. What we do not understand is why, despite the call of loop.exec() in the c++ code, the request is not processed (my example with the Q(gs)etworkAccessManager shows that it should processed) Actually you cannot instanciate properly a QgsProject with a WMS layer. To convince yourself, try to instanciate a QgsProject in python (in a standalone python script) from a .qgs project having a single wms layer: it will fail to instanciate the layer. > > > -- > Alessandro Pasotti > w3: www.itopen.it <http://www.itopen.it/>
