custom vfunc problem

[Ian Martin <martin_id vodafone co nz>]

Hi,
I'm slowly working my way through clutter trying to wrap it.  I've come 
up against a recurring problem where the C functions work but the 
wrapped functions don't; looking at the clutter source, I think the 
problem might be that the vfuncs are listed in the class_init function 
with a _real_ qualifier:
 klass->show = clutter_actor_real_show;
  klass->show_all = clutter_actor_show;
  klass->hide = clutter_actor_real_hide;
  klass->hide_all = clutter_actor_hide;
  klass->map = clutter_actor_real_map;

etc, and then in the source files this sort of thing happens:

  if (CLUTTER_ACTOR_GET_CLASS (self)->allocate == 
clutter_actor_real_allocate)
    goto check_layout;

which would mean that if every C++ instance is derived, it won't call 
the base class function; if possible, I should be pointing the vfuncs to 
the _real_ method, but as they're not declared in the headers this won't 
work either.

Is that correct?  Is there an example in another wrapped library of this 
being done successfully?

Ian.
