Re: GList and combobox problem

[Billy Patton <bpatton dal asp ti com>]

Here's my piece of code I create a selection list in a container box.
Hope this helps.
  cp = LaffCellNameIterator(db,1);
  while (cp)
  {
    gchar         *string ;
    GtkWidget     *label,*list_item ;
    if (! strcmp("BARINFO",cp)) goto NEXT;
    label     = gtk_label_new(cp);
    list_item = gtk_list_item_new();
    gtk_container_add(GTK_CONTAINER(list_item), label);
    gtk_widget_show(label);
    gtk_container_add(GTK_CONTAINER(list), list_item);
    gtk_widget_show(list_item);
    gtk_label_get(GTK_LABEL(label), &string);
    gtk_object_set_data(GTK_OBJECT(list_item),
                        list_item_data_key,
                        string);
    NEXT: cp = LaffCellNameIterator(db,0);
  }
