Problem when exit

[Florent Blanchon <florent blanchon gmail com>]

Hello,

 

 

I've a problem since i've implemented a menu bar, I've this message in the debug window :

 

 

 

 

Gtk::Justi(gtk:5618): GLib-GObject-WARNING **: instance of invalid non-instantiatable type `(null)'

 

(gtk:5618): GLib-GObject-CRITICAL **: g_signal_handlers_disconnect_matched: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed

 

(gtk:5618): GLib-GObject-WARNING **: instance of invalid non-instantiatable type `(null)'

 

(gtk:5618): GLib-GObject-CRITICAL **: g_signal_handlers_disconnect_matched: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed

 

 

 

The problem is only when I add the bar into the window, a VBox or a HBox. 

Below I've put the code for making the bar:

 

Gtk::Widget* PlotTest::Make_Menu(void)

{

 m_refActionGroup = Gtk::ActionGroup::create();

  

  //Choices menu, to demonstrate Radio items

   m_refActionGroup->add( Gtk::Action::create("PortMenu", "Port") );

  

  Portone = Gtk::RadioAction::create(group_userlevel1, "PortOne", "ttyS0");

  m_refActionGroup->add(Portone, sigc::mem_fun(*this, &PlotTest::PortSelection) );

   

  PortTwo = Gtk::RadioAction::create(group_userlevel1, "PortTwo", "ttyS1");

  m_refActionGroup->add(PortTwo, sigc::mem_fun(*this, &PlotTest::PortSelection) );

  

  m_refActionGroup->add( Gtk::Action::create("VitesseMenu", "Vitesse"));

   

  VitesseOne = Gtk::RadioAction::create(group_userlevel2, "VitesseOne", "115200");

  m_refActionGroup->add(VitesseOne, sigc::mem_fun(*this, &PlotTest::VitesseSelection) );

   

  VitesseTwo = Gtk::RadioAction::create(group_userlevel2, "VitesseTwo", "38400");

  m_refActionGroup->add(VitesseTwo, sigc::mem_fun(*this, &PlotTest::VitesseSelection) );

  VitesseThree = Gtk::RadioAction::create(group_userlevel2, "VitesseThree", "19200");

  m_refActionGroup->add(VitesseThree, sigc::mem_fun(*this, &PlotTest::VitesseSelection) );

  VitesseFour = Gtk::RadioAction::create(group_userlevel2, "VitesseFour", "9600");

  m_refActionGroup->add(VitesseFour, sigc::mem_fun(*this, &PlotTest::VitesseSelection) );

  m_refUIManager = Gtk::UIManager::create();

  m_refUIManager->insert_action_group(m_refActionGroup);

  m_refUIManager->add_ui_from_string(ui_info);

   

  return m_refUIManager->get_widget("/MenuBar");

  

   

}

 I don't really know the problem because I've done the same code as in the tutorial.

 

Thank you for your help.

Flo.
