def candidate_positions(_item_count)
  []
end

#go(_new_position) ⇒ Boolean

Overridden so all movement funnels — base Tuile::Component::List::Cursor#go_to_last, Tuile::Component::List::Cursor#go_to_first, etc., which all call #go — become safe no-ops on a disabled cursor. The instance is frozen, so a default mutating #go would raise.

@param _new_position

@return — always false.

Parameters:

  • _new_position (Integer)

Returns:

  • (Boolean)
