[Qgis-developer] editing widget - postgis table choice

[coviolo at libero.it]

hi there,

In qgis forum reccomend me to ask you:
I wonder if in the form attributes of a layer (PostgreSQL / PostGIS) -> 
changes widgets -> map values, it is possible to choose to take the data to be 
used, not only from the fields of the table already loaded
but also by another table in the postgresql database (eventualy not spatial 
table)?

look here for (italian) screenshot and original post...it is just to try to 
clarify the concept...i hope:

tnx to all
Luca
