Re: [wxlua-users] Questions about bindings

Hi Milind,

I'm not sure where the event-related changes came from; have you
executed any-bind-sync.lua on your version?

I'm not sure what may be needed for additional CallAfter support. I've
implemented the current one a while ago (it's in wxbase_base.i with an
override in wxbase_override.hpp).

Is there anything in particular you're looking to add support for?
It's always better to start with a specific method/class that may be
missing and to add just it.

Paul.

Particularly there are some templates functions like CallAfter. Now I am trying to see if there is any existing template function binding in any interface file so I can try to add that. Do you know of any that you looked at, or any idea of any particular thing to take care of to bind templates functions?
