In the gtk-demo program has a block as follows in the Tree View/Tree
Store example. This doesn't initialize the the child iter before using
it in the gtk_tree_store_append(), but the stamp is valid.
/* add children */
while (holiday->label)
{
GtkTreeIter child_iter;
gtk_tree_store_append (model, &child_iter, &iter);
gtk_tree_store_set (model, &child_iter,
HOLIDAY_NAME_COLUMN, holiday->label,
ALEX_COLUMN, holiday->alex,
HAVOC_COLUMN, holiday->havoc,
TIM_COLUMN, holiday->tim,
OWEN_COLUMN, holiday->owen,
DAVE_COLUMN, holiday->dave,
VISIBLE_COLUMN, TRUE,
WORLD_COLUMN, holiday->world_holiday,
-1);
holiday++;
}
