Gtk.TreeModel::iter_nth_child

function vfunc_iter_nth_child(parent:Gtk.TreeIter, n:Number):Boolean {
}

Sets iter to be the child of parent, using the given index.

The first index is 0. If n is too big, or parent has no children, iter is set to an invalid iterator and false is returned. parent will remain a valid node after this function has been called. As a special case, if parent is null, then the n<!-- -->th root node is set.
