I made a small application in Akka that has a hierarchy of actors (there is an ActorA that has several ActorB actors, and these ActorB actors have several ActorC actors). Now I'd like to add a small UI. This UI doesn't have any buttons, but just some labels that are modified when the ActorC actors receive certain messages from other actors. The problem that I have is that I must create a label for each ActorC actor, but the number (of ActorC actors) is not always the same, so I must create the ActorC actors in the first place, and then I must create the labels. I searched for tutorials on Scala Swing, but i just found old documentation or simple examples that are not useful in my case (something like press a button to do something). I even saw that several people used Java Swing in their Akka applications. I found a tool called Kamon, but i need to create an interface, not just monitoring my actors. Is there someone that can help me?
