Как обновить всю компоновку в шаблоне после изменения одного QWidget?

Question

У меня есть вот такой код который при нажатии кнопки "click_me" показывает или скрывает виджет "mini_window"

Но проблема в том что компановка окружающих виджетов не изменилась

Мне нужно что бы при нажатии кнопки внешнии виджеты тоже обновлялись

Но как вы видете в моем коде такого не происходит

Как решить данную проблему?

Answer 1

Я никогда НЕ изменяю код, сгенерированный Qt Designer'ом и мне не захотелось разбираться с этим кодом.

Я увидел вашу задачу так, попробуйте. Вам надо только поменять импорты и @QtCore.Slot(), т.к. у меня PyQt5.
