Как реализовать уменьшение и увеличение окна с последующим увеличением или уменьшением содержимого в нем, PyQt5

Question

Хочу реализовать с своей программе такую вещь, чтобы окно можно было увеличить или уменьшить, но при этом содержимое окна (кнопки, текст и т.д.) тоже меняли свой размер. Как это можно сделать?

И хотелось бы добавить вертикальные и горизонтальные скроллбары, чтобы листать содержимое окна, если оно полностью не влазит.

Вы реализовали свою форму в Qt Designer, поэтому вертикальные и горизонтальные скроллбары вам правильнее делать там же.

Внимание! Вы используете только абсолютное позиционирование - это ваше слабое место!

Вам надо хорошо изучить класс QLayout, который является базовым классом менеджеров геометрии https://doc.qt.io/qt-5/qlayout.html

QWidget::resizeEvent(QResizeEvent *event) - этот обработчик событий может быть переопределён в подклассе для получения событий изменения размера виджета, которые передаются в параметре события. Когда вызывается resizeEvent(), виджет уже имеет новую геометрию.

Т.е. метод resizeEvent - это то место где вы должны что-то сделать, если желаете что-то поменять при изменении размера окна.

Вы не предоставили минимальный модулю .ui , который содержит вашу форму, поэтому я вам продемонстрирую вариант того что вы задумали на своем минимальном примере.

        self.lineEdit.setText('Hello World')

        self.font = QtGui.QFont()
        self.font.setFamily("Arial")
        self.font.setPointSize(14)        
        self.setFont(self.font)
        
    def resizeEvent(self, event):
        w = self.size().width()
        if  w < 150:
            self.font.setPointSize(8)        
            self.setFont(self.font)
        elif 150 <= w < 300:

            self.font.setPointSize(24)        
            self.setFont(self.font) 
        elif 800 <= w < 1000:
            self.font.setPointSize(34)        
            self.setFont(self.font) 
        elif 1000 <= w < 1200:
