Re: [gnome-db] problem with g_value_get_int()

["Daniel Espinosa" <esodan gmail com>]

You have to init the GValue pointer first. You can use:


For upcomming Version 4.0 (the main difference is at GdaDataModel API)

GdaDataModel *model;
const GValue *integer;
GError *error = NULL;

integer = gda_value_new (G_TYPE_INT);

integer = gda_data_model_get_value_at  (model, 0, 0, &error);
/* All values in a Data Model must be unmodificable then use const GValue, this
will avoid compilation warnings */

Or can use (gda_value_new makes this for you :-)

integer = g_new0 (GValue. 1);

g_value_init (inteteger, G_TYPE_INT);

the code

GdaDataModel *dm;
gint i;
i = g_value_get_int (gda_data_model_get_value_at (dm, 0, 0));

output error

**CRITICAL : assertion G_VALUE_HOLDS_INT (value) failed

but if i do
i = (atoi) gda_value_stringfy (gda_data_model_get_value_at (dm, 0, 0));

i have i = 10,
which say gda_data_model_get_value_at return correct value.
now, why g_value_get_int doesn't work as it supposed to. how to use
g_value_get_int correctly?

thank you
