gtk:tree-model-iter-parent (model child)

model -- a gtk:tree-model object
child -- a gtk:tree-iter iterator

The gtk:tree-iter iterator to the parent.

Returns the iterator to the parent of child. If child is at the toplevel, and does not have a parent, then nil is returned. The child iterator will remain a valid node after this function has been called. The gtk:tree-model implementation is deprecated since 4.10. Please do not use it in newly written code.
