Как изменить размер виджета в Layout? Как работает sizepolicy?

Заранее извиняюсь за глупый вопрос. Я пытался по разному изменить размер на нужный мне, менял sizepolicy, капался в layout и много другое, но так и не вышло изменить на нужный мне размер, не прибегая к maximumsize, но я хочу что бы моё приложение можно было растянуть и что бы знак вопроса тоже растягивался, Пожалуйста подскажите как мне изменить размер виджета, а именно QLabel со знаком вопроса, мне нужно уменьшить размер примерно 20x20 px, если есть ещё какие то ошибки расскажите, буду очень благодарен, заранее спасибо =)

Вот тут я указываю minimumsize и ставлю в sizepolicy: minimum и ничего не меняется, но потом ставлю в sizepolicy: maximum и размер меняется как в minimumsize. Как это работает?
