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. The gtk:tree-model implementation is deprecated since 4.10. Please do not use it in newly written code.
