[gnomemm] Why Gnome::Canvas::Group derivation doesn't work??

[Davide Rocker Anastasia <s242248 studenti ing unipi it>]

If I derive an object by Gnome::Canvas::Group, it's invisible on canvas.
Why?? I write a cose like that:

class Obj : public Gnome::Canvas::Group {
	// ...
}

Obj(Gnome::Canvas::Canvas* canvas) :
	Gnome::Canvas::Group( *canvas->root() )
{
	// ....
}

Answer?!
