[PySide] how do you add a function to a script engine?

[سليمان السهمي]

I'm trying the following code:

def myAdd(context, engine):
   a = context.argument(0)
   b = context.argument(1)
   return a.toNumber() + b.toNumber()

myEngine = QScriptEngine()
fun = myEngine.newFunction(myAdd)

and getting:
AttributeError: 'PySide.QtScript.QScriptEngine' object has no attribute
'newFunction'
