Hi,
I have some doubts about QgsGeometryMap type.
I use layer from a PostgreSQL database and I use the
committedGeometriesChanges() signal to check if a geometry was changed.
By the QGIS API documentation I can see that committedGeometriesChanges()
return a QgsGeometryMap, that is so defined:
typedef QMap<QgsFeatureId, QgsGeometry> QgsGeometryMap
Iterating over the QMap object I have discovered that the 'key' portion
(QgsFeaureId) is ugual to the "id" attribute values (defined as table primary
key) of the features, is that fortuitous or there is a reason?
Is there a method to read the attribute values starting by the QgsGeometryMap
type?
Thanks.
Regards,
Enrico
