Roassal: Opacity

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.

Cheers,

Dennis

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.
