I have created a simple GtkAda GUI which contains a read-only Text_View
widget. The Text_View consists of a few lines which end with strings of
the format "= ABC123x\*.ext". When a user double-clicks over the
numeric part, only the "123" section is highlighted. I would prefer
either the "ABC123x" section or the "ABC123x\*.ext" section to be
highlighted. Is this possible (and simple for a Gtk newb like myself)?

Bump (I'll take the hint and give in if this also gets no replies).

Is it about text selection? If so there is a signal "extend-selection"
emitted upon. I never used it, but I guess that you can connect to it
and adjust selection's starting and ending iterators.
See:
https://developer.gnome.org/gtk3/stable/GtkTextView.html#GtkTextView-extend-selection
There is probably no typed form of this signal callback in GtkAda, so
you should use a general form with GValues.
