Re: tolua++ exported utility functions missing?

[Waldemar Celes <celes@...>]

In general, I use the following strategy to do that.

Create a C++ class, inheriting from the base class you want to extend in Lua.
The constructor of this new class expects a Lua table as an input parameter.
All virtual methods are implemented calling the appropriate Lua method 
stored in that table,
push the parameters and popping the results. You then export this derived 
class to Lua.

In Lua, you will be able to write:

local myClass = {
   method1 = function (self, ...)
   end,
   method2 = function (self, ...)
   end,
}

local myInstance = Derived_Class:new(myClass)

hope it helps.
