Re: gnome_program_init() error while loading main window with libglademm

[Viktor Dick <DickViktor gmx net>]

Yes, you should derive your window from Window. Loading it from the 
gladefile is done by:

---- begin main.cpp ----
...
Glib::RefPtr<Gnome::Glade::Xml> refXml = 
Gnome::Glade::Xml::create("fogwer.glade");
Gtk::Main kit(argc, argv);
FogwerGui* window;
window = refXml->get_widget_derived("app_main", window);
kit.run(window)
...

---- end main.cpp ----

Of course you should then also define a constructor for FogwerGui that 
takes the right arguments like seen in the documentation 
(http://gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch19s03.html), 
because then you will get a reference to refXml inside the constructor 
and can load the children of window by using refXml->get_widget().
