Instance Method Details

#candidate_positions(_line_count) ⇒ Array<Integer>

Parameters:

  • _line_count (Integer)

Returns:

  • (Array<Integer>)

def candidate_positions(_line_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.

Parameters:

  • _new_position (Integer)

Returns:

  • (Boolean) —

    always false.
