What window? In GTK terms it makes no sense.

When under window you assume Gtk_Text_View widget, e.g. put into 
Gtk_Scrolled_Window widget, then there are various operations to make 
the view scrolled to a desired position of the associated text buffer. 
E.g. to an iterator:

1. Connect to the text buffer insert signal ("insert-text")

2. From the signal handler take the iterator to the end of the text 
buffer (Get_End_Iter)

3. Scroll text view to that iterator (Scroll_To_Iter)
