TreeModel.iterNthChild

bool iterNthChild(out gtk.tree_iter.TreeIter iter, gtk.tree_iter.TreeIter parent, int n)

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.

Parameters

`iter`	the [gtk.tree_iter.TreeIter] to set to the nth child
`parent`	the [gtk.tree_iter.TreeIter] to get the child from
`n`	the index of the desired child

Returns

true, if parent has an n-th child
