python - "Underlying C/C++ object has been deleted" -


i'm having exception running simple application in python 2.7 qt. code:

# *-* coding: utf-8 *-* __author__ = 'luismasuelli'  import sys pyqt4 import qtgui  class streamwidget(qtgui.qwidget):      def __init__(self):          super(streamwidget, self).__init__(self)         self.initialize()      def initialize(self):          self.setwindowtitle("stream capture test")         self.resize(400, 300)         self.center()         self.show()      def center(self):          qr = self.framegeometry()         cp = qtgui.qdesktopwidget().availablegeometry().center()         qr.movecenter(cp)         self.move(qr.topleft())  def main():      app = qtgui.qapplication(sys.argv)     window = streamwidget()     sys.exit(app.exec_())  main()

sh*t:

runtimeerror: underlying c/c++ object has been deleted (at super() call line)
