How to make a widget in the center of the screen in PySide/PyQt?

Question

This code works, but I wonder if there is any simpler way:

def center(self):
    qr = self.frameGeometry()
    cp = gui.QDesktopWidget().availableGeometry().center()
    qr.moveCenter(cp)
    self.move(qr.topLeft())

Answer 1

just add this line to your main windows :

self.move(QtGui.QApplication.desktop().screen().rect().center()- self.rect().center())

Answer 2

self.move(QDesktopWidget().availableGeometry().center() - self.frameGeometry().center())
