Hej,
Is it possible to add an attribute to the writer when writing a geometry? It 
would appear this would be possible as explained in the 1.8 docs here 
(http://www.qgis.org/pyqgis-cookbook/vector.html#writing-vector-layers). 
However when I attempt something similar in 2.0 
I received the following errors

writer = QgsVectorFileWriter(Output, "CP1250", fields, 
layer.dataProvider().geometryType(),layer.crs(), "ESRI Shapefile")
fet = QgsFeature()
fet.addAttribute(0, QVariant(1)) 
AttributeError: 'QgsFeature' object has no attribute 'addAttribute' 
fet.setAttributeMap( { 0 : QVariant(1) }) 
AttributeError: 'QgsFeature' object has no attribute 'setAttributeMap' 

Currently I have a work around by creating a dictionary keyed by the feature id 
(i.e. corresponding to the order in which the geometries are created) and then 
looping through the layer a second time and updating the attributes. It appears 
that this second loop is unnecessary if I can write the attributes when writing 
the geometries to the QgsFeature().

Cheers,
Bjorn
