Is it possible in Roassal to draw nodes in a layout with different opacities? A simple example would be: drawing a tree with nodes less opaque the deeper their nesting level is.
Well... You will need to manually assign the color to the nodes.
I've just made the following example:
Alpha is interesting to make translucent colors.

view shape rectangle borderColor: Color veryVeryLightGray.
view nodes: (T copyFrom: 1 to: 10) forEach: [ :aClass |
view shape rectangle borderColor: Color white.
view nodes: aClass methods.
view shape line color: (Color blue alpha: 0.2).
view edges: aClass methods from: #yourself toAll: [ :m | m queryAllOutgoingInvocations opposites asArray ].
view gridLayout.
].
view gridLayout.
