Annotation	PT-symmetrization of quantum graphs is proposed as an innovation where an adjustable, tunable nonlocality is admitted. The proposal generalizes the PT-symmetric square-well models of Ref. [M. Znojil, Phys. Rev. D 80, 045022 (2009).] (with real spectrum and with a variable fundamental length theta) which are reclassified as the most elementary quantum q-pointed-star graphs with minimal q=2. Their equilateral q=3,4,... generalizations are considered, with interactions attached to the vertices.
