All providers and python bindings have been updated accordingly. Currently supported variant types by providers are String, Int and Double. Other API changes: - QgsField - type info as QString is now typeName() and setTypeName() - added variant type (QVariant::Type) info: type(), setType() - QgsFeature - removed fields() - use QgsVectorDataProvider::fields() - removed boundingBox() - use QgsGeometry::boundingBox() - QgsVectorLayer - removed fields(), fieldCount(), getDefaultValue() - use directly QgsVectorDataProvider - QgsVectorDataProvider - getDefaultValue() - field now addressed by id, returns variant - QgsLabel - setLabelField() - field now addressed by id git-svn-id: http://svn.osgeo.org/qgis/trunk/qgis@6833 c8812cc2-4d05-0410-92ff-de0c093fc19c
