Good morning, thanks to the new Qgis, I can make a really pratical interface to my postgis database. I want to make use of relationnal value in the editing form. The table I use to populate the list is a spatial table.
I would like to restrict the list of available values in the form to the objects within the current extent of my map. I found an example wich is ok but I would like to make use of a variable instead of a fixed extend (GeomFromWKT()). The example I tried is here : http://www.3liz.com/blog/rldhont/index.php?post/2012/11/06/Spatial-operators-in-QGIS-expression Thanks a lot, Mathieu -- Mathieu BOSSAERT Responsable du système d'information Membre de la Fédération des Conservatoires d'espaces naturels www.reseau-cen.org
