I'd like my visualizations showing inheritance to be UML-like. That is, I'd like arrow heads to be empty. I found some classes (RTEmptyArrowHead, etc.) and thought they might be the answer. However, I can't get it to work in the following code. Do those classes work?

I'm using Moose suite 6.0 on Windows 10. | b line | b := RTMondrian new. b shape circle size: 3. b nodes: RTShape withAllSubclasses. "b shape arrowedLine withShorterDistanceAttachPoint." line := RTEmptyArrow new. b shape line withShorterDistanceAttachPoint. b edgesFrom: #superclass. b layout forceWithCharge: -500. b build. ^ b view <http://forum.world.st/file/n4915133/RTEmptyArrowAttempt.png> -- View this message in context: http://forum.world.st/Changing-arrow-head-types-in-RTMondrian-tp4915133.html Sent from the Moose mailing list archive at Nabble.com. _______________________________________________ Moose-dev mailing list Moose-dev(a)list.inf.unibe.ch https://www.list.inf.unibe.ch/listinfo/moose-dev

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 <http://forum.world.st/file/n4915232/EmptyArrowLines.png> -- View this message in context: http://forum.world.st/Changing-arrow-head-types-in-RTMondrian-tp4915133p491… Sent from the Moose mailing list archive at Nabble.com. _______________________________________________ Moose-dev mailing list Moose-dev(a)list.inf.unibe.ch https://www.list.inf.unibe.ch/listinfo/moose-dev
