I don't believe there is a way to get the size before the change. I do
not believe that there is much requirement for that. If you are looking
for a more elegant solution, you would have to reimplement GtkViewport
or GtkScrolledWindow to keep track of the visible view now and before.

After you create the scroll window in main(), connect like:

I have a question concerning how to set which part of a GtkTextBuffer is

To explain the situation, consider this sample code:
