[Moose-dev] migrating to roassal - MOArrowedOrthoVerticalLineShape

I am usings the code to produce the attached image. view shape: (MOArrowedOrthoVerticalLineShape new). view edges: inheritance from: #superclass to: #yourself. How do I achieve that with Roassal? And just to document something I got working... previously to hide lines while keeping the layout I was using... view shape: (MOStraightLineShape new color: Color white). view edgesFrom: [ :xx | xx - 1 ]. and now... (view edgesFrom: [ :xx | xx - 1 ] ) do: [ :edge | edge - ROEdge ] . cheers -ben
