[Moose-dev] Re: Changing arrow head types in RTMondrian

Thanks for all the pointers. Here's a working solution with the right direction for inheritance:

| b | b := RTMondrian new. b shape circle size: 20. b nodes: RTShape withAllSubclasses.

b shape arrowedLine head: RTEmptyNarrowArrow asHead; "See other RTLineDecorationShape" withShorterDistanceAttachPoint; color: (Color blue alpha:0.4).

b edges connectTo: #superclass.

b layout forceWithCharge: -500.

b build. ^ b view
