I am trying convert my code from PyQt4 to PyQt5 but I am getting errors.

import sys
from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import QApplication

QPixmap.grabWindow(QApplication.desktop().winId()).save(filename, 'jpg')

AttributeError: type object 'QPixmap' has no attribute 'grabWindow'
