How to undo Qt.FramelessWindowHint from a QMainWindow?

Question

The application that I am trying to make needs a frameless window in the first stage, then I need to set it framed back.

so I need to inactivate the following line --> self.setWindowFlag(Qt.FramelessWindowHint)

I searched a lot but I had no satisfying answer. Can you please help me, guys?

Thanks in advance.

Hope you are almost there, inside your mainwindow init, First you have to add this line while initialization,

Flags = QtCore.Qt.QWindowFlags(QtCore.Qt.FramelessWindowHint | QtCore.Qt.WindowStaysOnTop)
self.setWindowFlags(Flags)

Later you can set None to windowflags. Hope this helps.
