Gtkada keep textcurswithin window

[ldries46]

I do have a correct working program which is using GTK the latest version.
The only thing I cannot find is how in a text window keep the last line 
within the window.
Eveytime when the program updates the window the program upperline in the 
window is visible alse when there are to much line to be seen all within the 
window. This means that the text cursor disappears out of the window. I just 
want to automatically set the up down slider to position the window in a way 
that I can see the text cursor

I am using Gtk+3.

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)
