How to remove child_anchor from TextView?

["Andrew E. Makeev" <andrew@solvo.ru>]

Hi all,

How could I remove child_anchor from TextView buffer?
I've tried that way:

Gtk::TextIter iter = textBuffer->get_iter_at_child_anchor (myAnchor);
textBuffer->erase (iter, iter);

Any suggestion?
Hopefully, I will get answer from GTKMM list...

thanks in advance,
-andrew
