Hello,
considering a vector map, do you know a simple way to perform multiple
selections (e.g. highlighting a set of polygons) interactively either on
the display (tcltk or wxpython) or through a X monitor ? the aim in the
end is to update database records on the basis of a cat list.
I tried the addon v.digatt but I can't run it correctly (I think a
possible reason is my vector is linked to a pg db driver, and the module
was tested only with dbf driver).
Thank you,
Vincent.

Coudl this help?
d.extract help
Description:
Selects and extracts vectors with mouse into new vector map.
It's not perfect but maybe a starter.

Thank you Markus,
I tried several methods like d.extract, or
d.where | v.what map=zonpi > test and extracting cat values from the
test file. Now I am wondering if it is worth (let's better say realistic
given my skills) to try and write a custom module, inspired from
v.digatt.
As I already had a little experience in perl and wxwidget (frontend for
data capture in postgres database) I would appreciate later on to
involve in writing a python add-on, but like everyone, my principal
ennemy is the lack of time !
Beside data storing, treatment, analysis, I think it would be great to
improve data *production* tools, and it's what I would like to
contribute.
Vincent.
