Hi Recently I have been looking a bit at the new geometry classes and there is one thing I do not understand: if QgsLineStringV2 is derived from QgsCurveV2 and QgsPolygonV2 is derived from QgsSurfaceV2, why is not the same approach used for multi-part geometries? Currently QgsMultiLineStringV2 and QgsMultiPolygonV2 are subclasses of QgsGeometryCollectionV2 - but why they are not derived from QgsMultiCurveV2 and QgsMultiSurfaceV2 respectively?
It looks like OGR uses that approach too (multi-polygon from multi-surface and multi-linestring from multi-curve): http://www.gdal.org/classOGRGeometry.html Regards Martin _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
