gtkTreeModelIterNthChild {RGtk2} | R Documentation

## gtkTreeModelIterNthChild

### Description

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.

### Usage

    gtkTreeModelIterNthChild(object, parent = NULL, n)

### Arguments

``object`` | A `GtkTreeModel`.
``parent`` | The `GtkTreeIter` to get the child from, or `NULL`. [ allow-none ]
``n`` | Then index of the desired child.

### Value

A list containing the following elements:

`retval` | [logical] `TRUE`, if `parent` has an `n`th child.
``iter`` | The `GtkTreeIter` to set to the nth child.
