[paragasu <paragasu gmail com>]

i am very new into this gtk and libgnomedb. this is my first attempt
write one, i have one
function.

[snip]
GtkWidget *page_1(GdaConnection *conn)
{
        GtkWidget *vbox;
        GdaQuery *query;
        GdaDict *dict = gda_dict_new();
        gda_dict_set_connection(dict, conn);

        query = gda_query_new_from_sql(dict, "SELECT * FROM account", NULL);
        GdaDataModel *acc_list_model = gda_data_model_query_new(query);
        g_object_unref(query);
        
        query = gda_query_new_from_sql(dict,
                        "SELECT * from account"
                        "WHERE acc_id=##/*name=:'acc_id' type:gint descr:'account id'*/",
                        NULL);
        
        GdaDataModel *payment_model = gda_data_model_query_new(query);
        g_object_unref(query);

        GdaParameterList *params =
gda_data_model_query_get_parameter_list(GDA_DATA_MODEL_QUERY(payment_model));
        GdaParameter *param = gda_parameter_list_find_param(params, "acc_id");
        

    GtkWidget *grid = gnome_db_raw_grid_new(acc_list_model);
        GtkWidget *form = gnome_db_raw_form_new(payment_model);
        
        gtk_box_pack_start(GTK_BOX(vbox), grid, FALSE, FALSE, 3);
        gtk_container_add(GTK_CONTAINER(vbox), form);

        return vbox;
}

[/snip]

the code compile well. except it give up warning  and segmentation fault.
