Hello
I'm creating an app with gtkmm using Gtk :: Builder according to the book and I can make the app work.
I am now intending to derive this class which is already derived from Gtk :: ApplicationWindow.
How do I start the constructor of the base class it has (BaseObjectType * cobject, and const Glib :: RefPtr <Gtk :: Builder> & builder) in the derived class?

Ex:

###### example.h ######

class GtimerGui : public Gtk::ApplicationWindow
{
public:
GtimerGui(BaseObjectType* cobject, const Glib::RefPtr<Gtk::Builder>& builder);
 ~GtimerGui();
Gtk::ApplicationWindow *main_window;
Glib::RefPtr<Gtk::Builder> sp_FileBuilder;

};

###### example.cpp ######

GtimerGui::GtimerGui(BaseObjectType* cobject, const Glib::RefPtr<Gtk::Builder> &builder)
: Gtk::ApplicationWindow(cobject), sp_FileBuilder(builder)

{

}

GtimerGui::~GtimerGui()
{
}

###### Main.cpp #######

nt main (int argc, char *argv[])
{
   auto app = Gtk::Application::create (argc, argv, "liomar.org.example");
   auto refFileBuilder = Gtk::Builder::create();
   try
   {
 refFileBuilder->add_from_file("/home/suporte/Projeto_2019/GTimer/gtimer.glade");
  }
   catch(const Glib::FileError &ex)
   {
  std::cerr << "FileError: " << ex.what() << std::endl;
 
   }
   catch(const Glib::MarkupError& ex)
   {
  std::cerr << "MarkupError: " << ex.what() << std::endl;
   }
   catch(const Gtk::BuilderError& ex)
   {
  std::cerr << "BuilderError: " << ex.what() << std::endl;
   }
   GtimerGui *gtimer = nullptr;
   refFileBuilder->get_widget_derived("m_main_window", gtimer);  
   if(gtimer)
   {
    app->run(*gtimer);
    }
   delete gtimer;  
   return 0;
}

##### Derived_Class.h #####

class GtimerController : public GtimerGui
{
public:
 GtimerController();
 ~GtimerController();
};

##### Derived_Class.cpp ####

GtimerController::GtimerController()

{

}

GtimerController::~GtimerController()
{
}
