[GRASS-user] wxpython gui: d.vect.thematic raises error

[G. Allegri]

You're right Michael. Sorry for not being exhaustive.
I'm doing test on Kubuntu 7.10
Grass: 6.3.0 RC5
wxwidgets: 2.8.4.0
python: 2.5.1

TWO ERRORS with vdigit and v.vect.thematic

FIRST ERROR: vdigit

I've loaded (inside the manager) a polygon layer and an empty line
layer to digitize the latter.
Then I've run vdigit from the "tools" menu. I've selected the line
layer as the layer to be digitized.
I get an error window with:

"Unable to initialize display driver, see README file for more information."

Nothing happens... and I loose control on the GUI. I have to kill it
and restart Gra
ss


SECOND ERROR: d.vect.thematic

I create a thematic vector map (from the gui). It's a point layer. I
ask to use graduated_points on a double type attribute.

Execution failed: 'd.vect.thematic map=topsoil_completo at tesi
type=point column=Ece themetype=graduated_points themecalc=interval
size=9 maxsize=25 nint=10 colorscheme=blue-red --q'

GRASS_INFO_ERROR(16631,1): *** You must open a display monitor ***

The same error raises if I launch it from commandline both in wxgrass and tcltk.
Again, I loose control on the GUI and got to kill it.


In Grass tcltk this command works correctly:

d.vect.thematic -s map=topsoil_completo at tesi type=point column=Ece
layer=1 icon=basic/circle size=9  maxsize=25 nint=10
pointcolor=255:0:0  linecolor=0:0:0 startcolor=255:0:0
endcolor=0:0:255  themetype=graduated_points monitor=none
themecalc=interval colorscheme=blue-red
