[Glade-users] GtkClist Problem (Seg fault)

[guillaume at ruch.infini.fr (guillaume ruch infini fr)]

Hello all,

I've Got a problem with creayion of a GtkClist.... I'm developping a small
mysql interface which only deals withs 3 tables. I've got 3 buttons which
may build each a dynamic clist to display the content of the selected
table in the same widget. When I compile it, it returns :

(project2:1390): Gtk-CRITICAL **: gtk_object_set_data_full: assertion
`GTK_IS_OBJECT (object)' failed
Erreur de segmentation

gtk_clist_new...OK

(project2:30722): Gtk-CRITICAL **: gtk_object_set: assertion
`GTK_IS_OBJECT (object)' failed
gtk_object_set_data_full...OK

(project2:30722): Gtk-CRITICAL **: gtk_object_set_data_full: assertion
`GTK_IS_OBJECT (object)' failed
Erreur de segmentation


The Widget is called dyn_clist and is called by an event on the button
"CLients" Here's the code :

GtkWidget *dyn_clist (gchar *nom_table)
{
  GtkWidget *Stox_main;
  GtkWidget *scrolledwindow1;
  GtkWidget *clist1;
  GtkWidget *label;
  gint      i;
  gint      cols = 3;
  gchar     *sql;
  MYSQL_RES *res_str;
  MYSQL_ROW db_row;
  MYSQL_FIELD *field;


        gchar     *row[15] = {"", "", "", "", "",
                              "", "", "", "", "",
                              "", "", "", "", ""};

 scrolledwindow1 = gtk_scrolled_window_new (NULL, NULL);
 gtk_widget_show (scrolledwindow1);
  sql = g_strconcat("select * from ", nom_table, 0L);
  g_print("sql is: %s\n", sql);
  if (mysql_query (conn, sql) != 0)
   {
      g_print("Echec de la requete...\n");
      return 0L;
   }
  res_str = mysql_store_result (conn);
 g_print("mysql_store_result...OK\n");

  cols = mysql_num_fields(res_str);

  clist1 = gtk_clist_new (cols);
  /*gtk_object_set_data_full(GTK_OBJECT(Stox_main),
             "clist1", clist1,
             0L); */
  gtk_widget_show (clist1);
  gtk_container_add (GTK_CONTAINER (scrolledwindow1), clist1);
  gtk_clist_column_titles_show (GTK_CLIST (clist1));



for (i = 0; i < cols; i++)
    {
       mysql_field_seek(res_str, i);
       field = mysql_fetch_field(res_str);
       label = gtk_label_new (field->name);
       gtk_widget_show (label);
       gtk_clist_set_column_widget (GTK_CLIST (clist1),
                                    i, label);
       gtk_clist_set_column_width (GTK_CLIST (clist1),
                                   i, 80);
    }



   while ((db_row = mysql_fetch_row (res_str)) != 0L)
     {
        for (i = 0; i < cols; i++)
          {
              row[i] = db_row[i];
          }
        gtk_clist_append(GTK_CLIST(clist1), row);
     }



  return scrolledwindow1;
}

   gtk_container_add (GTK_CONTAINER(lookup_widget(StoX_main,
                    "vpaned_table_bottom")), scwindow_table);
   gtk_widget_show(scwindow_table);

}


I'm newbie in devlopping applications, so I hope someone will know better
than me how to correct this error....
