Yes. It should be the platform you need. Doru On Mon, Jul 7, 2014 at 11:21 AM, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > Thank you for all the suggestions.

Re: [Pharo-users] drawing morphs with athens

by Peter UhnÃ¡k

Thank you for all the suggestions. I looked more closely at Roassal and it seems that it might have everything we would need. Basically the next step in the project is to create extensible drawing tool for modelling languages (UML/Petri nets/what have you), so we need to be able to draw any arbitrary shapes and their compositions (e.g. UML StateMachine composite state might have plethora of subelements). So If I understand correctly Roassal/Trachel should be able to provide us with everything at the visual layer or it is possible to (easily) extend it and add custom shapes.
