[Qgis-developer] addVectorLayer and PostGIS layer: forcing geometry type

[luca_manganelli at comune.trento.it]

Hi all,

I have a PostGIS layer with multiple geometries: POINT, MULTIPOINT,
LINESTRING and MULTILINESTRING.

I tried to add a layer in this way:

  uri = QgsDataSourceURI()
  uri.setConnection ("cartografia", "5432", "schema", "postgres", "pppp")
  uri.setSql ("sql=GeometryType('wkb_geometry') IN
('LINESTRING','MULTILINESTRING')")
  self.iface.addVectorLayer (uri.uri(), tab, "postgres")

but QGIS complains that it cannot add GEOMETRY types. How can threat this
layer as LINESTRING ?
