gtk-tree-model-rows-reordered (model path iter order)

model -- a gtk-tree-model object
path -- a gtk-tree-path instance pointing to the tree node whose children have been reordered
iter -- a valid gtk-tree-iter iterator pointing to the node whose children have been reordered, or nil if the depth of path is 0
order -- a list of integers mapping the current position of each child to its old position before the re-ordering

Emits the "rows-reordered" signal on model. This should be called by models when their rows have been reordered.
