rows_reordered_with_length

Description:

public void rows_reordered_with_length (TreePath path, TreeIter? iter, int[] new_order)

Emits the rows_reordered signal on this.

See [signal@Gtk.TreeModel:GtkTreeModel:rows-reordered].

This should be called by models when their rows have been reordered.

this	a `GtkTreeModel`
path	a `GtkTreePath` pointing to the tree node whose children have been reordered
iter	a valid `GtkTreeIter` pointing to the node whose children have been reordered, or null if the depth of `path` is 0
new_order	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`
length	length of `new_order` array
