How to make a Window always stay above the others in PYQT5?

Question

There is no guarantee that it will stay on top always, especially if other programs use the same feature, I’ll have to be a little more honest about it, programs at the top have always bothered me, I’m the user, I know what I want at the top and what I don’t want, of course if it is an option within the program chosen by the user it would be acceptable to use it, but if it is forcibly and not a user option I would refuse to use such a program.

Going back to the technical part, basically the flag to leave at the top is Qt.WindowStaysOnTopHint

<objeto>.setWindowFlags(<objeto>.windowFlags() | QtCore.Qt.WindowStaysOnTopHint)

Change <objeto> by the context (widget or Qmainwindow) it will apply, remembering that the same program can have multiple windows, a basic example:

from PyQt5 import Qt, QtCore, QtWidgets
import sys

app = QtWidgets.QApplication(sys.argv)

w = QtWidgets.QWidget()
w.setWindowFlags(w.windowFlags() | QtCore.Qt.WindowStaysOnTopHint)
w.resize(800, 600)
w.show()
sys.exit(app.exec_())

Note that I used .windowFlags() to get the default flags, then with the | "match" with QtCore.Qt.WindowStaysOnTopHint.

Almost everything from Qt in C++ in applicable similarly in Pyqt5 and as an alternative to Pyqt there is also pyside, which is quite similar, so consult the official Qt documentation can help you:
