Good example. One note though, If using glade files for the GUI Construct, be sure that your textView widget is not contained inside of a viewport. This is the default action for Glade 3.2 and gave me a ton of grief until I realized that I had 1 extra widget in my glade file compared to the example above.

About t73net comment : With glade 4 and a TextView inside a ScrolledWindow, the above code works without problem.
