Glib::RefPtr<Gdk::Window> win = get_window();
Glib::RefPtr<Gdk::GC> some_gc = Gdk::GC::create(win);
The program console showed:
(Hello:2839): Gdk-CRITICAL **: gdk_gc_new: assertion `drawable != NULL'
Surely the error message says exactly what it was saying last week, namely
that your ref ptr 'win' contains a NULL, which means your program fails at
line one. Concentrate on that. When that is solved the GC-creation will
work, and then the rest of the program becomes interesting.
