How about a sort of widget/object factory?

So you'd set the default implementation for a type:
  gtk_object_factory_set_default_implementation (factory,
                                                 GTK_TYPE_LABEL,
                                                 MY_CUSTOM_LABEL_TYPE);

And then in the widget/object xxx_new() functions instead of calling
g_object_new() they call:
  gtk_object_factory_create (factory, GTK_TYPE_LABEL, ...);


Does that work?


Applications could then use different sets of widgets for different
parts of the interface, just by switching the default factory:
  gtk_set_default_object_factory (factory);
