Как плавно скрыть Qwidget, чтобы родительский Qwidget также уменьшался?

Question

Мне нужно, чтобы Qwidget "mini_window" менял свою высоту с обычной на 0 и наоборот. когда была нажата кнопка "click_me" И родительский Qwidget "main_winow" подстраивал свой размер

Я использовал QPropertyAnimation из урока по Qt5 Я пытался изменить максимальный размер "mini_window", но я не нашел такого параметра в QPropertyAnimation, поэтому я просто использовал (size)

Но после нажатия на кнопку мой Qwidget "main_winow" остается того же размера, а компановка не обновляется.

Почему так происходит и как это исправить?

Я перенес всю логику в class QtMainWindow. Вам надо только поменять импорты, т.к. у PyQt5.

from PyQt5.Qt import *


class Ui_MainWindow(object):

        if MainWindow.objectName():
