VerticalActionButton::draw() does the text.
World::draw() is responsible for getting it called.

Playfield::on_primary_button_press() is where you should start to find
the call sequence. It's somewhere in the middle and should you get what
you need to know.

It's an object that knows how to move itself, drawing something around
it and suchlike is outside of the responisibilities of that class.

You're welcome.
BTW maybe you should try

I think I'm not the only one who'd like to know wheter it'll help you
with further investigations.
