Of course. This example current uses a boost::shared_ptr, but it used to
just be a raw pointer:
struct RegionListDisplayModelColumns : public
Gtk::TreeModel::ColumnRecord {
RegionListDisplayModelColumns() {
add (name);
add (region);
add (color_);
}
Gtk::TreeModelColumn<Glib::ustring> name;
Gtk::TreeModelColumn<boost::shared_ptr<ARDOUR::Region> > region;
Gtk::TreeModelColumn<Gdk::Color> color_;
};
