Hi Vivien,
in your last version you removed gda_data_model_get_value_at_column().
It was an handy function to retrieve a value from a column name, which
is also mentioned here
http://library.gnome.org/devel/libgda-4.0/unstable/ch07s06.html#id2552536.
I cannot find a replacement for it, may you please indicate me what I
should use?
gda_data_model_get_value_at (model, gda_data_model_get_column_index(model, "mycol"), row, &error);
