Re: [Pharo-dev] Starting with Roassal 2
Yes, you can use SVG path as a shape for an element. What you chose really depends on your objective. If you want to draw nodes (elements) and connect them with edges (lines), I guess, the preferred API is Roassal2.

Re: [Pharo-dev] Starting with Roassal 2
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.

Re: [Pharo-dev] Starting with Roassal 2
well thats not an one liner and you still connect elements with it. I just wanted to pass coordinates to a line and draw it. So I would prefer it if I could pass points instead of elements.

Re: [Pharo-dev] Starting with Roassal 2
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.

Re: [Pharo-dev] Starting with Roassal 2
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.

[Pharo-dev] Starting with Roassal 2
Ok here comes the first question how I change the background color of RTView ? also when I do this v := RTView new. shape := RTEllipse new size: 20; color: Color red. shape := shape + RTLabel. es := shape elementOn:'hello'. v add: es. line := RTDirectedLine new pointsFrom: 20@20 To: 30@30. es2 := line element.v add: es2. es @ RTDraggable. v @ RTDraggableView . v open. I am getting an error MNU Array >> element why ?
