Hi Christian,

Tx for replying.

I got it to work by initializing the iterator from the buffer, not the view:
view.buffer.get_iter_at_line(). I do not know why it does not work the
other round too -- I hope to learn someday  : - )

It is all working nicely now. Vala and valadoc sites have excellent
documentation - which is a boon for newbies like me.

For the first time, I am beginning to enjoy putting up GUI's -- this used
to be such a pain earlier.
