yep. But we need this one instantiation to register the GType for our
widget. you may want to look into our SimpleDraw example again
(attachment to
http://mail.gnome.org/archives/gtkmm-list/2006-November/msg00184.html)
where we create a temporary SimpleDraw in simpledraw_glade.cc
(simpledraw_get_type())

libglade sets the GObject's properties in glade_standard_build_widget(),
then later the GObject is wrapped, but then the properties have already
disappeared (as described).

no, not in glade itself, but we will want to load a glade file with our
custom widgets in it via Gnome::Glade::Xml::create and this is where the
properties don't get set.

glade's interface designer also does not apply our custom properties
correctly to our widgets, but that seems a bit of a different story to me.

i may have found a solution for the Gnome::Glade::Xml::create - issue,
will investigate and post later (maybe tomorrow).
