Only for widgets that are not the child of some container widget.
Unless you're doing something special, this means you only have to
delete toplevel windows.  And you can use std::auto_ptr<> for that.

class Foo
{
  ...
  std::auto_ptr<Gtk::Window> window_;
  ...
  void load_xml();
  ...
};

void Foo::load_xml()
{
  using Gnome::Glade::Xml;

  const Glib::RefPtr<Xml> xml = Xml::create(glade_mainwindow_filename);

  Gtk::Window* mainwindow = 0;
  window_.reset(xml->get_widget("mainwindow", mainwindow));

  ...
}
