Gtk.TreeStore.prepend

### Method

# Gtk TreeStoreprepend

#### Declaration [src]

    void
    gtk_tree_store_prepend (
      GtkTreeStore* tree_store,
      GtkTreeIter* iter,
      GtkTreeIter* parent
    )

#### Description [src]

Prepends a new row to `tree_store`. If `parent` is non-`NULL`, then it will prepend the new row before the first child of `parent`, otherwise it will prepend a row to the top level. `iter` 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()`.

#### Parameters

`iter` | `GtkTreeIter`
| An unset `GtkTreeIter` to set to the prepended row.
| The argument will be set by the function.
| The data is owned by the caller of the function.
`parent` | `GtkTreeIter`
| A valid `GtkTreeIter`
| The argument can be `NULL`.
| The data is owned by the caller of the function.
