Handling WINDOW_EVENT

Hello,

I am trying to handle window events. As an example I used vizdragdrop.py from the python directory in Vizard.

I can not find good documentation on how to use this. But the example really helps. So in my subclass of viz.EventClass I have an callback with viz.WINDOW_EVENT and I use addWindowMessage to add the message I want to listen to.

In the callback function I receive the e object with it's e.lParam and e.wParam. But according the documentation of my message I need to report back. I should return 0 if I have handled the message or call DefWindowProc if I didn't. How do I do that in Vizard? Should I just return 0 and call DefWindowProc myself (ctypes) or is there a build in method?

Greetings, Joran.
