ah thank you very much, thats exactly what I was looking for. I will study Trachel too. I also found that I can do something similar using a SVG path with Roassal.

I think the intention of Roassal lines is to be connected with elements. If you want only draw lines without any connection to elements, use directly Trachel.

I have checked RTDirectedLine and it is not supposed to use the way you want. Basically RTEdge is the object you want to manipulate with. I do not know what is the objective of your example. But there is way how you could write it. -=-=- | v elements models | models := (10 to: 60 by: 1). v := RTView new. elements := (RTEllipse new size: #yourself; color: Color red) + RTLabel elementsOn: models. v addAll: elements. RTEdge buildEdgesFromObjects: models from: #yourself to: [ :i | i // 2 ] inView: v.

Re: [Pharo-dev] Starting with Roassal 2

by kilon alios

to answer myself, view color changes via canvas so it is v canvas color: Color black. I also found a way to create an edge looking at the tests. this is the complete code now v := RTView new. shape := RTEllipse new size: 20; color: Color red. shape := shape + RTLabel. es := shape elementOn:'hello'. v add: es. el1 := RTBox element. el2 := RTBox element. el1 translateTo: 20 @ 20. el2 translateTo: 60 @ 80. edge := RTLine edgeFrom: el1 to: el2. "es2 := edge element."v add: edge. "RTEdge buildEdgesFromObjects: (1 to: 20) from: [ :i | i // 2 ] to: #yourself inView: v". "RTGridLayout on: es". es @ RTDraggable. v @ RTDraggableView . v canvas color: Color black. v open. probably there is an easier way to do this so I am taking a look at both tests and examples.
