Hi again!
Maybe you could also help me with an other issue: I need to save the
coordinates of the polygon vertices to a list for later processing. I
tried with "thepoints = thepoly.asMultiPoint()" but get an empty list.
In the API Documentation I found that the function asMultPoint() needs a
MultiPoint-geometry as input (what makes no sense to me, as I don't need
to convert it if it is already MultiPoint…?).
Is there an other function that does what I want, or am I calling the
asMultiPoint function wrong?
Regards and sorry for disturbing again!

Der QGIS developers,
I'm trying to write a python plugin to reate input data for one of our
models. It basicly converts three shape files with special fields to a text
file.
I have a buildings vector (polygon) layer containing three polygons (which I
created for testing). This layer is called "build" in the code. To extract
its geometries, I wrote a little function:
def extract_poly_geometry(self, layer):
feature = QgsFeature()
geom_list = []
while layer.dataProvider().nextFeature(feature):
geom_list.append(feature.geometry())
return geom_list
