I am new to gtkmm, but I will give it a shot and try to help you anyway. 
Apparently, you are trying to access a non-static member function 
without an object and outside that member function's class' context. 
Here is an excerpt I took from the document "The Drawing Area Widget" [1]:

  "The get_window() method is a part of the Gtk::Widget class, so if 
you put this code into a derived widget's implementation then you can 
call it just as it is, otherwise you'd use some_widget.get_window()."
