python 2.7 - QGraphicsScene crashes PyQt4 -


  • windows xp
  • python 2.7
  • pyqt 4

when run following code inside python interactive shell

from pyqt4 import qtgui qtgui.qgraphicsscene()

python crashes.

why?

it's done this:

from pyqt4 import qtgui import sys qapp = qtgui.qapplication(sys.argv) scene = qtgui.qgraphicsscene() ... qapp.exec_()
