Re: Textview not scrolling in Client

[Jeff Hallock <Jhallock WBandA com>]

Just came across this at 
http://live.gnome.org/GTK2-Perl/FrequentlyAskedQuestions#head-ca3eac3d2016b4893bea39bcf1c1b3565ce450ad

This should make sure that every time you add text to the widget,it is scrolled to the bottom.

# create a mark at the end of the buffer, with right gravity,
# so that when you insert text, the mark always stays on
# the right (at the end).
my $end_mark = $buffer->create_mark ('end', $buffer->get_end_iter, FALSE);
# every time we insert text, scroll to that mark.
$buffer->signal_connect (insert_text => sub {
        $textview->scroll_to_mark ($end_mark, 0.0, TRUE, 0.0, 1.0);
});
