Yes.  It is explicitly specified that tree iters can be copied by value.
See for instance here

http://developer.gnome.org/gtk/stable/GtkTreeModel.html#gtk-tree-iter-copy

Oops!
GtkTreeIter *default_iter --> GtkTreeIter default_iter;

It's question about:
default_iter = *iter; <-- is that normal?

I can give you more verbose example(it's pseudo-code, not C):
prepare_iter()
{
  GtkTreeIter iter;
  gtk_tree_store_insert_after( ... , &iter , ...);

  add_new_entry(model, &iter);
}

add_new_entry(GtkTreeModel, GtkTreeIter *iter)
{
  GtkTreeIter default_iter;
  GtkTreeStore *store = GTK_TREE_STORE(model);

  if(iter != NULL)
  {
default_iter = *iter; <-- i need that
  }
  else gtk_tree_store_append(... , &default_iter, ...);
  gtk_tree_store_set(store, &default_iter, 1, "name", -1);
}

So, i need to call add_new_entry() somewhere outside with some model and
second NULL arg.

If you're interested, this is how i doing right now:

It's work, but i don't like it.

This is pointer assignment: default_iter will denote the same chunk of
memory as iter.  What exactly should be abnormal here?

This is invalid code: wrong number of arguments of wrong type.  And, of
course, default_iter is possibly being used uninitialised.

GtkTreeIter assignment

2012-10-30 Thread Vlasov Vitaly 
Hello list.

Is that normal, to assign one GtkTreeIter to another?

For example:
void add_new( ... , GtkTreeIter *iter)
{
GtkTreeIter *default_iter;

if(iter != NULL)
{
   default_iter = iter; <-- is that noraml??
}
gtk_tree_store_append(&default_iter);
}
