Gtk.TreeModel::rows-reordered
Description: Reference for signal Gtk.TreeModel::rows-reordered

### Signal

# Gtk TreeModel::rows-reordered

#### Declaration

    void
    rows_reordered (
      GtkTreeModel* self,
      GtkTreePath* path,
      GtkTreeIter* iter,
      gpointer new_order,
      gpointer user_data
    )

#### Description [src]

This signal is emitted when the children of a node in the `GtkTreeModel` have been reordered.

Note that this signal is not emitted when rows are reordered by DND, since this is implemented by removing and then reinserting the row.

Default handler: | The default handler is called before the handlers added via `g_signal_connect()`.

#### Parameters

`path` | `GtkTreePath`
| A `GtkTreePath` identifying the tree node whose children have been reordered.
| The data is owned by the caller of the function.
`iter` | `GtkTreeIter`
| A valid `GtkTreeIter` pointing to the node whose children have been reordered, or `NULL` if the depth of `path` is 0
| The data is owned by the caller of the function.
`new_order` | `gpointer`
| An array of integers mapping the current position of each child to its old position before the re-ordering, i.e. `new_order``[newpos] = oldpos`
| The argument can be `NULL`.
| The data is owned by the caller of the function.
