[luabind] Deriving in lua, more then 10 parameters for a method

[Roman K. <kub...@gm...>]

Helo.

I'm using a third party library for my application (JUCE), this library has
a large class called LookAndFeel, i want to expose that class to lua via
luabind.

I started to do the work following the documentation, and using the
luabind::wrap_base approach, i got a few methods bound and it's all working
fine, until i hit a problem. Some of the methods in the original
LookAndFeel class have more then 10 parameters, and i can't bind those
methods using this approach.

One of the solutions i found would be to change the parameters and wrap
them in a structure, and that would be a good idea but i can't change the
original LookAndFeel class, and changing the class that derives from
luabind::wrap_base - that i'm implementing - so that it's methods take a
structure as a parameter instead of the actual parameters, makes those
methods unusable (luabind never calls them, since the parameter count and
type does not match the original LookAndFeel class).

Is there a way to solve this somehow, can i increase the limit of 10
parameters in luabind (trying to extend the ARITY macro over 10 causes
loades of compile errors).

Any help is welcome.

My class looks like:
class LLookAndFeel : public LookAndFeel_V3, public luabind::wrap_base
{
     virtual void drawButtonBackground (Graphics &g, Button &b, const
Colour &c, bool over, bool down) override
            { call<void>("drawButtonBackground", boost::ref (g),
boost::ref(b), c, over, down); }
        static void def_drawButtonBackground (LookAndFeel_V3 *ptr, Graphics
&g, Button &b, const Colour &c, bool over, bool down)
            { return (ptr->LookAndFeel_V3::drawButtonBackground
(g,b,c,over,down)); }

/* More methods are needed that have more then 10 parameters */
}

Best regards.
