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 nth 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.
