I know... So I tried to come up with a smaller example. However, it's
not showing the same, but another problem. Until that is fixed, I think
investigating the old problem is pretty much useless.
The attached project tries to model the situation I have in my real app.
It compiles & runs under my Mac.
Essentially all I try to do is to create a interface in C++
(IEventReceiver), a subclass (PyIEventReceiver) to overload the pure
virtual methods of the base-interface so it can be overloaded in python
and a test-class that invokes the OnEvent-method in a previously set
Then in the python-test-script, I try and instantiate the test-object,
and subclass the PyIEventReceiver. The latter is the problem. When
passing that into the test-object and invoke the test-method, I don't
get the overloaded method invoked.
How do I achieve that?
I'm not sure if the two problems are related - but until this works,
it's moot to try and make the other problem go away.
