Recall that we have pointed out that a few widgets provide native scrolling support. Well, Gtk::TextView is one of them. This means you should use Gtk::Container#add method, rather than Gtk::ScrolledWindow#add_with_viewport(child), to add Gtk::TextView to the scrolled windows.

When handling text buffers, you will be dealing with terms such as((*ofset*))and((*index.*))As with all text widgets in GTK+, text is stored in UTF-8 strings, hence individual characters may be more than one byte long. This may effect the overall meaning or value that offset and index will represent. You can tell what is the size in bytes for an UTF-8 character by looking at the initial bit(s) of the character. Consult the table on the left for details.
