Of the Gtkmm way:


 class GFoo : public Glib::Object
 {
 	Glib::PropertyProxy<int> m_bar;
 public:
 	GFoo();
 	Glib::PropertyProxy<int> property_bar(int value)
 		{ return m_bar; }
 	// allow using the property on const objects, enforcing
	// the read-onlyness.
 	Glib::PropertyProxy<int>_ReadOnly property_bar(int value) const
 		{ return m_bar; }
 };

  GFoo::GFoo()
 	: Glib::ObjectBase(typeid(GFoo)),
 	m_bar(*this, "bar")
 {
 	
 }


Icing on the cake: you can even use g_object_get_property() and
g_object_set_property() on it by accessing the underlying GObject.

Also note to C++ haters: it is simplier if you don't care about GObject.
