[Qgis-user] How to define generic VectorFileWriter

[Reginald]

Hi,

For those who are interrested in the result I post this script:

////////////////////////////////////////////
#script uses selected features of parcellayer as geometry for editable other
vector layer
#make sure there is only one layer editable, otherwise only the first
occuring layer will be used

from qgis.PyQt.QtCore import *
from qgis.core import QgsWkbTypes

perceellayer=None
editlayer=None
layers = [layer for layer in QgsProject.instance().mapLayers().values()]
for lyr in layers:
    if lyr.name() == "parcels":
        perceellayer = lyr
    if lyr.type() == QgsMapLayer.VectorLayer:
        cap = lyr.dataProvider().capabilities()
        if cap & QgsVectorDataProvider.AddFeatures:
            editlayer = lyr
percelen = []
features = perceellayer.selectedFeatures()
geom = None
for f in features:
    if geom == None:
        geom = f.geometry()
        #perc = f["primarynum"] + f["bisnumber"] + f["expletter"] +
f["expnum"]
    else:
        geom = geom.combine(f.geometry())       

velden = editlayer.fields()
prov = editlayer.dataProvider()
feat = QgsFeature(velden)
feat.setGeometry(geom)
iface.openFeatureForm(editlayer,feat,updateFeatureOnly=True)
(res, outFeats) = editlayer.dataProvider().addFeatures([feat])
print("done")

///////////////////////////////////////

Regards,
