One way to do this is to handle the window's mouse events by implementing
the mousePressEvent and mouseMoveEvent handler methods in a widget subclass:

class Window(QWidget):

In the first method, you would do something like this, checking that the right
mouse button is pressed and store the screen position of the mouse cursor:

    def mousePressEvent(self, event):
    
        if event.buttons() == Qt.RightButton:
            self.dragPos = event.globalPos()
            event.accept()

In the second, you would check that the right button is pressed and move the
window by the change in the position of the mouse cursor, storing the new
position for the next time the event handler is called:

    def mouseMoveEvent(self, event):
    
        if event.buttons() == Qt.RightButton:
            self.move(self.pos() + event.globalPos() - self.dragPos)
            self.dragPos = event.globalPos()
            event.accept()

Note that this only handles right clicks on the window itself. Any clicks on
child widgets within the window will be handled by those widgets instead.
