B4J Question [SOLVED) lanterna

[a.consorti]

Hi everyone,
having the need to create interfaces in a terminal environment I came across this old thread:

https://www.b4x.com/android/forum/threads/create-a-gui-in-text-mode.124780/

I tried to replicate it but when in doubt I open a new one in the hope of understanding how to intercept the events of a Button Click.
The code can be found in the old thread.
Thanks in advance for the help

It seems you really messed up that link, might want to look into that.

Also, what is lanterna?
