### Method

# Gtk TreeStore insert_before

deprecated: 4.10

#### Declaration [src]

    void
    gtk_tree_store_insert_before (
      GtkTreeStore* tree_store,
      GtkTreeIter* iter,
      GtkTreeIter* parent,
      GtkTreeIter* sibling
    )

#### Description [src]

Inserts a new row before `sibling`.

If `sibling` is `NULL`, then the row will be appended to `parent`’s children.

If `parent` and `sibling` are `NULL`, then the row will be appended to the toplevel.

If both `sibling` and `parent` are set, then `parent` must be the parent of `sibling`. When `sibling` is set, `parent` is optional.

The `iter` parameter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call `gtk_tree_store_set()` or gtk_tree_store_set_value().

Deprecated since: 4.10

Use `GtkTreeListModel` instead.
