gtk:tree-store-is-ancestor (store iter descendant)

store -- a gtk:tree-store object
iter -- a valid gtk:tree-iter iterator
descendant -- a valid gtk:tree-iter iterator

True, if iter is an ancestor of descendant.

Returns true if iter is an ancestor of descendant. That is, iter is the parent, or grandparent or great-grandparent, of descendant. The gtk:tree-store implementation is deprecated since 4.10. Use the gtk:tree-list-model object instead.
