Custom scrollbar doesn't translate to pyqt from designer

I have designed everything properly in the PyQT designer. In there, the scrollbar looks as it should (customised by the css). Here is the code:
self.scrollArea = QtWidgets.QScrollArea(self.frame) self.scrollArea.setGeometry(QtCore.QRect(50, 200, 731, 601)) self.scrollArea.setStyleSheet("QScrollBar:vertical {\n" " border: 0px solid #999999;\n" " background:white;\n" " width:10px; \n" " margin: 0px 0px 0px 0px;\n" " }\n" " QScrollBar::handle:vertical { \n" " \n" " min-height: 0px;\n" " border: 0px solid red;\n" " border-radius: 4px;\n" " background-color: gray;\n" " }\n" " QScrollBar::add-line:vertical { \n" " height: 0px;\n" " subcontrol-position: bottom;\n" " subcontrol-origin: margin;\n" " }\n" " QScrollBar::sub-line:vertical {\n" " height: 0 px;\n" " subcontrol-position: top;\n" " subcontrol-origin: margin;\n" " }\n" "\n" "QScrollArea, QAbstractScrollArea, QWidget{\n" " border-radius: 60px;\n" " background-color: rgb(255, 255, 255);\n" "}\n" "") self.scrollArea.setWidgetResizable(True) self.scrollArea.setObjectName("scrollArea")However, when I launch this as a python application, the scrollbar looks like the default one. I am struggling to find the reason for this issue.

Hi and welcome to devnet,
I would rather use a triple-quoted string so you can more cleanly write the style sheet.

Then please provide a minimal script that allows to reproduce this issue.

@SGaist Here is the entire class if it helps you :)

Tested on a Mac with PyQt installed through conda. Package is
pyqt-5.12.3.The scrollbar is changed.
Note that your code cannot be run directly, it's missing a QMainWindow instance as well as the QApplication part.
