It works fine for me too, but only when I use to get_widget_derived
approach. Not when I use the reparent_widget approach implemented in the
GladeDialog class I was talking about in my previous post. 

I'll paste the important parts of the GladeDialog, this may clarify how
I transfer properties and the widget-tree from dialogs to allow improved
encapsulation. 

//.h
GladeDialog::GladeDialog(const std::string& gladexmlfile, 
       const std::string& root)
{
   //obtain gui spec
   try
   { 
      m_gladexml = Gnome::Glade::Xml::create (gladexmlfile, root);
   } catch(const Gnome::Glade::XmlError& e)
   {
      std::cout << "GladeDialog: " << e.what() << std::endl; 
   }

   //adapt some properties and take over widgets
   Gtk::Dialog* dialog = 0L; m_gladexml->get_widget(root, dialog);

   //Widget ->
   {
      int width, height; 
      dialog->get_size_request(width, height); 
      this->set_size_request(width, height);  
   }

   //Container ->
   this->set_border_width(dialog->get_border_width());

   //Bin ->
   
   //Window ->
   this->set_title(dialog->get_title());
   this->set_type_hint(dialog->get_type_hint());
   this->set_modal(dialog->get_modal());
   {
      int width, height; 
      dialog->get_default_size(width, height); 
      this->set_default_size(width, height);   
   }
   this->set_resizable(dialog->get_resizable());
   this->set_gravity(dialog->get_gravity());

   //Dialog
   // ..
 
   this->remove(); //remove the one object contained in this 'Bin' 
   m_gladexml->reparent_widget (dialog->get_child()->get_name(),
*this);   

   delete dialog;   
}
