This is not supported on python2

    def __setattr__(self, key, value):
        if key == 'obj':
            return super().__setattr__(key, value)

If you run on python2 will get this error. return super().setattr(key, value) TypeError: super() takes at least 1 argument (0 given) Exception TypeError: "'NoneType' object is not callable" in <bound method HelloTriangleApplication.del of <main.HelloTriangleApplication object at 0x000000000306F888>> ignored

Hello @mackst. Thanks for the report. You are right, I didn't test on Python2 after adding this class.
