I am not sure to understand what you need exactly.

I just created a new builder, called RTLayerBuilder.

A simple example:

-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTLayerBuilder new.
b addLayer: 'ABC'.
b addLayer: 'BCA'.
b addLayer: 'DEFA'.
b open

-=-=-=-=-=-=-=-=-=-=-=-=

It gives:

By being a builder, you can enjoy all the facilities for defining shapes and interaction:

-=-=-=-=-=-=-=-=-=-=-=-=
| b |
b := RTLayerBuilder new.
b shape circle 
size: 20; withText.
b verticalGap: 30.
b horizontalGap: 40.
b addLayer: 'ABC'.
b addLayer: 'BCA'.
b addLayer: 'DEFA'.
b open

-=-=-=-=-=-=-=-=-=-=-=-=

Cheers,

Alexandre

Hi,
 
I would like to display a some elements by layers with Roassal.
Each element has a layer number (from 1 to 6 in the exemple) and is linked to elements from other layers (green lines).
So each line of the visualization contains elements of one layer.
 
I have tried with all the treeLayout but I don’t get a representation by the wanted layers.
 
So I asked Usman and he tells me to use userDefinedEdges:.
So I defined virtual edges from all elements from a layer to all the elements to the next layer.
 
And I get:
<image001.png>
All the nodes are on the good line but the linked between them (in green) are horribly crossed.
 
Which virtual nodes should I add to make it works ? Or should I create/use a layout ?
 
Thanks for your answers,
 
Cheers,
Vincent
