Yes, I am currently working on the "virtual layer" provider we were talking about here some time ago. It is first developed as a c++ plugin (even if the development may lead to some pull requests). This is still under development. But I have a very first implementation where a vector layer can be used in a Spatialite database. Adding geometry support to virtual *fields* is another solution. I guess it would need to state what type is used by expressions to describe geometries (WKT ? WKB ?). It may be easier to have than a full virtual layer implementation (which also offers other possibilities, spatial joins for instance) _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
