Feature request #8936
Enhancement to Expression Builder : make some variables available in the expression builder
|Pull Request or Patch supplied:||No||Resolution:||fixed/implemented|
|Easy fix?:||No||Copied to github as #:||17604|
As i explain in the mail on the QGis users list, I would like to make use of relational values 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 which 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,
