g_emblemed_icon_add_emblem (GEmblemedIcon *icon,
GIcon *emblem_icon,
const char *origin)
{
GEmblem *emblem;
emblem = g_new (GEmblem, 1);
emblem->icon = g_object_ref (emblem_icon);
emblem->origin = g_strdup (origin);
icon->emblems = g_list_append (icon->emblems, emblem);
}
Or something along those lines. As you can see, a GEmblem struct would
appear in this implementation as well. Open for discussion whether it should
be exposed as an object or not.

But doesn't GEmblemedIcon represent that difference nicely ?
