[Qgis-user] WFS: Change symbolization (outline color/thickness and fill) using Python in QGIS.

[Stefan Giese (WhereGroup)]

Hi mikeE

here is a small example based on your code:

uri = 
'https://www.geodatenportal.sachsen-anhalt.de/wss/service/ST_LVermGeo_ALKIS_WFS_OpenData/guest?&service=WFS&BBOX=1332412,6708967,1333423,6709355&restrictToRequestBBOX=1&VERSION=auto&typename=ave:GebaeudeBauwerk&srsname=EPSG:25832&preferCoordinatesForWfsT11=false&pagingEnabled=true'
lyr14 = QgsVectorLayer(uri, "LSA: ALKIS Gebäude (WFS)" , 'WFS')
# Farbe ändern
lyr14.renderer().symbol().setColor(QColor("red"))
lyr14.renderer().symbol().symbolLayer(0).setStrokeColor(QColor("blue"))
lyr14.renderer().symbol().symbolLayer(0).setStrokeWidth(0.5)
#lyr14.triggerRepaint() #braucht es nur wenn schon geladen
# Legende updaten
iface.layerTreeView().refreshLayerSymbology(lyr14.id())
QgsProject.instance().addMapLayer(lyr14)
