I made a pyqt GUI in QT Designer 4.8.5. I converted the .gui file to .py and wrote some code to run the application. However, the outcome is not what I wished for.
Expected (as shown when running preview in QT Designer):
Result when running the converted .py:
As you can see, the content of the centralwidget is pulled (stretched) behind the title bar. The text in the labels is also a bit blurry.
It used to work without any problems, but I accidentaly upgraded pyqt (was trying something) and since then, it's broken. The code of my converted .py file is below.
Anybody knows what's changed in pyqt and how to fix it? The gui code is written in the file UFA_gui.py:
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'UFA_UIv0_1.ui'
#
# Created by: PyQt5 UI code generator 5.9.2
#
# WARNING! All changes made in this file will be lost!
