[Qgis-developer] New feature's needed, create geometry from attribute

[kimaidou]

Hi

What about using the field calculator ? I think I have seen a method in the
"geometry" tools : something like geomfromwkt ? If needed, we could simply
add a way to modifiy the features geometry with the field calculator, and
it will do the trick.
