Re: Problem with signals and libglademm

[johnmb <johnmblackburn googlemail com>]

In may main.cc  -  the following statements :-

            // Load the interface

            Glib::ustring glade_file;
            glade_file = glade_file + working_directory.c_str() +
"glade/kas_master.glade";
            main_gui = Gnome::Glade::Xml::create(glade_file);

            welcome_screen welcome(main_gui, screen_texts);
            welcome =
dynamic_cast<welcome_screen&>(*main_gui->get_widget("welcome_screen"));

            Gtk::Main::run(welcome);


the class "welcome_screen is of the form:-

class welcome_screen : public Gtk::Window {

   ..........
   ..........

}


I get the following error when trying to compile main.cc:-
