@suppi Yes, but you spend a lot less time on events than in most GUI libraries. Part of that is the clever way in which the appropriate threads spin up "automatically" with the eventspace stuff.

You never even declare that you're starting the event loop for the GUI... you just say "okay, show the window now" and it starts up. That sounds pretty magical but it works well enough.

It also uses a class/object system I initially hated, but I know ACK is very good for the job it's doing.
