 Yes, I have looked into the bindings and it seems to be that some other wx
classes are missing, such as wxVListBox, wxHtmlListBox, wxServer, wxClient,
wxDataViewCtrl + helper classes etc. Which I use all of them in my C++ app.
that's sad I was hoping for a more feature complete wxlua. I would like to
help implement them but I'm not that comfortable with the lua embedding api
yet. To be totally honest I don't even know the Lua language fully yet.

I have basically a wxWidgets C++ application and would like to embed a
script language to allow users to create GUI in some kind of sand-boxed
environment. Some of the application needs to be converted to wxLua. And it
is there where wxThreads, wxVListBox, wxDataViewCtrl etc, are used (no
bindings for them yet). The pros for wxLua is that the user writing the
script does not have to think about pointers, memory etc. So to allow the
user to use C++ code is just the opposite of what I'm trying to do.

What do you think, Is it better to use wxPython instead? Although its more
feature complete but it uses more memory, slower, new language, and is more
difficult to embed. And if I continue with wxLua do you think it will be a
big task to try to create bindings for the rest of the wxWidgets library.

Thanks
