Разработка PyQT5

Question

Я занимаюсь разработкой приложения с графическим интерфейсом, которое называется поиск дубликатов.Что он делает, так это то, что если пользователь набирает или разбивает на группы несколько имен, он находит, какие имена дублируются, и выводит имена без дублирования и сортирует их в алфавитном порядке.

Теперь я хочу развить это еще дальше, посколькуэта версия была только 0.0.

1) Когда я изменяю размер окна, поля ввода и вывода и кнопки застревают в одинаковом положении с одинаковым размером.Я хочу, чтобы они изменяли размеры и перемещали в зависимости от размера окна.

2) Я хочу, чтобы текст заполнителя был больше и выровнен по центру текстового поля.

3) МойФункция closeEvent не работает.Я хочу спросить пользователя, действительно ли он хочет выйти.

4) Наконец, я не могу получить подменю в работе с файловым меню.«Новый» должен очистить весь текст в полях (ввод и вывод), в основном перезапустить приложение.и кнопка выхода в меню «Файл» должна задать тот же вопрос из номера 3.

Я много пытался исследовать, но это единственные вопросы, которые мне не удалось выяснить.
