GtkTreeModeliter_nth_child

Declaration [src]

gboolean
iter_nth_child (
  GtkTreeModel* tree_model,
  GtkTreeIter* iter,
  GtkTreeIter* parent,
  int n
)

Description [src]

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.

	The `GtkTreeIter` to set to the nth child.
	The argument will be set by the function.
	The data is owned by the caller of the function.
`parent`	`GtkTreeIter`
	The `GtkTreeIter` to get the child from.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`n`	`int`
	The index of the desired child.

Return value

Returns:	`gboolean`
	`TRUE`, if `parent` has an `n`-th child.
