I don't include Glib::Object, it complains about not being able to use gobject_
class Ellipse : public GooCanvas::ItemSimple
{
_CLASS_GOBJECT(Ellipse,GooCanvasEllipse,GOO_CANVAS_ELLIPSE,Glib::Object,GObject)
_IMPLEMENTS_INTERFACE(Item)
public:
explicit Ellipse( const Glib::RefPtr<Item>& parent,
gdouble center_x = 0.0,
gdouble center_y =
0.0,
gdouble radius_x = 0.0,
gdouble radius_y = 0.0 ) ;
_WRAP_PROPERTY("center-x",gdouble)
_WRAP_PROPERTY("center-y",gdouble)
_WRAP_PROPERTY("radius-x",gdouble)
_WRAP_PROPERTY("radius-y",gdouble)
} ;
Has these methods that its generating:
Ellipse::Ellipse(const Glib::ConstructParams& construct_params)
:
Glib::Object(construct_params)
{}
Ellipse::Ellipse(GooCanvasEllipse* castitem)
:
Glib::Object((GObject*)(castitem))
{}
Well, this isn't anything if not frustrating :D

GooCanvasEllipse just inherits from GooCanvasItemSimple, which in turn
derives from Glib::Object. So you don''t need any multiple inheritance.
However, you do need multiple inhertiance when dealing with "interfaces":
Search for "implements" (such a G_IMPLEMENT_INTERFACE) in the .c files.
