"widget" is a Gtk::Image* or a Gtk::DrawingArea*:

Glib::RefPtr<Gdk::Drawable> drwbl = widget->get_window();
Glib::RefPtr<Gdk::Pixbuf> pxb;
pxb = Gdk::Pixbuf::create(drwbl, drwbl->get_colormap(),
                           0, 0, 0, 0,
                           widget->get_width(),widget->get_height());
try {
  pxb->save("Image.png", "png");
}
catch (Glib::Exception &e) {
  std::cerr << "could not save: " << e.what() << std::endl;
}
