[gnomemm] Creating a custom Gnome::Canvas::Item

[Michael Babcock <mbabcock la creatureshop henson com>]

Hello,

Does anybody have an example that creates a new Canvas::Item class by 
derivation in C++?

There is no default constructor, and I'm not sure how to use these:

/home/michael/install/include/libgnomecanvasmm-2.0/libgnomecanvasmm/item.h:89: 
candidates
   are: Gnome::Canvas::Item::Item(GnomeCanvasItem*)
/home/michael/install/include/libgnomecanvasmm-2.0/libgnomecanvasmm/item.h:88: 
                   Gnome::Canvas::Item::Item(const Glib::ConstructParams&)
/home/michael/install/include/libgnomecanvasmm-2.0/libgnomecanvasmm/item.h:84: 
                   Gnome::Canvas::Item::Item(const Gnome::Canvas::Item&)

Thanks.
