Dear Moritz,
after implementation of wxPython GUI I started with a new grass
session with the command grass63 -wxpython. Then the following
message came up:
grass63 -wxpython Cleaning up temporary files..... Starting GRASS ...
Traceback (most recent call last): File
"/usr/local/grass-6.3.0RC5/etc/wxpython/gis_set.py", line 28, in from
gui_modules import utils File
"/usr/local/grass-6.3.0RC5/etc/wxpython/gui_modules/utils.py", line 1
There must be more to the traceback, and the interesting part is always
at the end...
Also: it would be helpful if you could give the following info when
reporting issues with wxgrass:
- OS
- python version
- wxpython version

[GRASS-user] modify feature's values interactively

Hi
2008/3/26, Moritz Lennert :
is it possible within GRASS to modify feature's values (of
the feature attribute table) interactively (e.g. like in
ArcGIS, where I can select an object within the view which
then can be modified/removed...)?
you mean to modify attribute data of vector objects? If so,
yes, you can use v.digit or digitizer in wxPython GUI
(experimental).
Moritz:
IMHO there should be a solution outside of the digitizer (i.e.
without risking any alteration of the actual map), something
along the lines of "d.what.vect -e".
Christian, if this is what you need, you will have to use it
with the "old-style" x-monitors from the command line, i.e.:
d.mon x0 d.vect YourMap d.what.vect -e YourMap
This is typically one element which would be GUI-only as I
don't think it would make much sense to program an interactive
command line version...
So maybe something to think about for wxgrass.
hm, it wouldn't be so difficult to implement, sorry, back to the
reality;-) Basic implementation is here
http://trac.osgeo.org/grass/changeset/30745
see

Cool !
However, I just can't get it to work:
I have
GRASS 6.3.svn (spearfish60):~> v.db.connect -p roads Vector map is
connected by: layer table in database through driver with key
Querying in display mode works as expected:
East: 596271.961722 North: 4924483.851675
Map: roads Mapset: PERMANENT Type: Line Line: 51 Longueur:
1416.211362 couche: 1 catégorie: 3
Driver: dbf Database:
/home/mlennert/GRASS/DATA/spearfish60/PERMANENT/dbf/ Table: roads
Key column: cat cat : 3 label : secondary highway, hard surface
But when I try to query it in edit mode, I get:
"No database record available"
Also: probably the button's properties should be changed so that
you can click on it again directly to change from one mode to the
other. Currently you have to click on another button and then back
on the query button to change mode.
