I am attempting to implement a MVVM WPF application in Python.Net.
The ViewModel class needs to implement the INotifyPropertyChanged interface.
class ViewModel(System.ComponentModel.INotifyPropertyChanged): def __init__(self): pass
vm = ViewModel()
gives exception: "TypeError: interface takes exactly one argument"
I am not sure what is the reason.
I remember a post last year saying the the interface inheritance is implemented in a development brand and not integrated into main branch. not sure if it is the reason.
I am using python 2.1.0.dev1.
thanks
