I have some problem making a custom event. It seem like the initilizer is not visible in the scope. Why is that? I have put a little test program in an attachment, can anybody tell me, what is wrong with it? ---

For some reason the allocator (constructor) function for Wx::Event is undefined - I’ve just checked the sources and I don’t know why SWIG is doing that. It may be a regression. Can you inherit from Wx::CommandEvent or some other Event class instead. You are calling super with the parameters for Wx::CE anyway. That works fine for me (as per the sample). PS - at line 21 you call Wx::EvtHandler.process\_event. #process\_event is an instance method, not a class method. Every Window, plus the App, has an event\_handler (with an accessor). You pass the event to one of those, normally the one where the event originates so that it can bubble upwards. hth alex
