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

I'm not a Roassal expert to provide a final answer, but just to shortcut things in case there is a typo in the line above, "line" is a variable and can't be sent as a message to the object returned by #shape. Are you getting any error message like "MessagenotUnderstood: XXXX>>line" ?

Hi,
use can use `#head:` for `arrowedLine`, or `#headStart:`/`#headEnd` for `doubleArrowedLine`.
Note that you are `connect(ing)From: #superclass`, so you would have to reverse it if you want to use the `arrowedLine` (because the line points to the subclass), or use the `doubleArrowedLine`.
E.g.
| b | b := RTMondrian new. b shape circle size: 3. b nodes: RTShape withAllSubclasses.
"b shape arrowedLine withShorterDistanceAttachPoint; head: RTEmptyNarrowArrow asHead."
"or"
b shape doubleArrowedLine withShorterDistanceAttachPoint; headStart: RTEmptyNarrowArrow asHead; headEnd: RTNoShape new.
b edges connectFrom: #superclass.
b layout forceWithCharge: -500. b build. ^ b view

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

Hi,
You seem to be having some fine!
Please keep the questions coming.
Cheers, Doru
