Stephan,
The G_OPT_OUTPUT option generate well the check box "add tree layer" in
my script GUI.
My problem, now is how to add the raster output while I want to set his
name by the script ? I succeed with g.copy my_raster_name to
output_raster_name. The copy is well displayed but this creates a copy
what is not very convenient...
Cheers,
Frank

Hi Frank,
Using GRASS standard parser options is a good practice. Unfortunately,
it does not yet generate the "add to tree layer" check box in the
AddOn GUI (though I hope that can be added in core though).
You can use e.g. G_OPT_R_OUTPUT and still choose a non-standard
key-name for the option in your script with a line like this:
#% key: my_option_key_name
Cheers,
Stefan

Stephan,
Your last message makes me search after G_OPT_OUTPUT. I had never
realized that this option makes the "add to tree layer" check box
appear on the script GUI.
All my scripts create rasters without G_OPT_OUTPUT option (because the
name of output are handled by the script itself) and so, without check
box. Using d.rast could keep interesting i think in order to select
witch one should be display or not, but for the moment I can (may be)
overtake that limitation by using the G_OPT_OUTPUT option (I will see).
Sorry for confusing. And thank you very much for your help. I let you
see if the ticket you had post is appropriate.
Cheers,
Frank

Hi Frank,
My guess is that the GRASS standard parser options [1] (e.g.
G_OPT_R_OUTPUT, G_OPT_R_OUTPUTS,G_OPT_V_OUTPUT, …) would be used
in order to determine what has to be / could be added to the map
display…
But I am no GUI dev, and cannot tell for sure, hope experts on
that part of the code could chime in …
And yes, I agree that a convenient function in the Python library
for adding a map in the currently active layer manager would be a
nice new feature (if it does not exist and I just overlooked it)…
Maybe another ticket?...
Cheers
Stefan

*Subject:* Re: [GRASS-user] d.rast in python script
Hi Stephan,
Thank you for the ticket. One thing seems to me important. Some
(of my) scripts can generate numerous rasters and one or two
cumulative raster. I don't want to add base rasters but only the
few cumulative. If the script GUI have a check box, how to make
the choice between these I want to display and those I don't want ?
For my point of view, the use of d.rast inside the script, as we
do for all other grass command, should be possible, in order to
display what we want to display.
Cheers,
Frank

Hei Nikos, Frank,
I opened an enhancement ticket, and asked to activate the "Add
created map(s) into layer tree" also for addons:
https://trac.osgeo.org/grass/ticket/3686. No idea what changes
this would require…
Would that cover your needs, Frank, or do you have a more
interactive use in a python script in mind?
You can start a wx monitor (d.mon wx0) and add a map there,
but I have not found a way to address the currently active Map
Display …
This would probably require additional function(s) in the
Python libraries…?
Maybe this question is better asked at the developer list
(thus I put grass-dev in CC).
Cheers
Stefan

Thank you everybody for your help. Do you know why a
run_command("d.rast"... in a python script is not
enough to display a raster ? I don't understand why
this command is so different.
Display a raster map where?
Nikos
In the active map display (and respective Layer manager) as
d.rast do it with gui...
