New Option - gnocl::text -text

Job done. Why include this switch? Suppose a script has the following line of code, perhaps as part of a feeback process in which the text widget is only needed for feedback purposes:

set msg [glob [pwd]/*.*]

set win [gnoc::window]

gnocl::window -child $win

$win insert end $msg

Why not simply the process? to just:

set msg [glob [pwd]/*.*]

gnocl::window -child [gnocl::text -text $msg]

In fact, when there's no need to use rich text formatting this is really useful as the underlying Gtk+ library function will delete the buffer contents too!
