There are basically two ways (there's a third, but it's fairly
innefficient, so I won't bother):


TreeIter iter;

if (list.GetIterFirst (out iter)) {
	do {
		string s = (string)list.GetValue (iter, 1);

		if (s == "first string") {
	} while (list.IterNext (ref iter));


list.Foreach (new TreeModelForeachFunc (SearchForeach));

bool SearchForeach (TreeModel m, TreePath p, TreeIter i)
	string s = (string)m.GetValue (i, 1);

	if (s == "my search term") {
		found_iter_class_field = i;
		return true;

	return false;
