Hi, Does anyone know how to delete a child\_anchor from a text buffer. I read something about unreffing it, but couldn’t figure out how. On a related note there seems to be a bug in get\_iter\_at\_child\_anchor. In contrast to the documentation I need to provide two arguments to the method, although as far as I can tell it only uses the first argument (the anchor). Edwin * * * Take Surveys. Earn Cash.

Use Gtk::TextBuffer#delete. start\_iter = buffer.get\_iter\_at\_child\_anchor(anchor) end\_iter = buffer.get\_iter\_at\_child\_anchor(anchor) end\_iter.forward\_char buffer.delete(start\_iter, end\_iter) Gtk::ChildAnchor is represented as a char. See: [http://developer.gnome.org/doc/API/2.4/gtk/GtkTextBuffer.html#gtk-text-buffer-insert-child-anchor](http://developer.gnome.org/doc/API/2.4/gtk/GtkTextBuffer.html#gtk-text-buffer-insert-child-anchor) > On a related note there seems to be a bug in get\_iter\_at\_child\_anchor.

I fixed the bug. ## Thanks, kou * * * Take Surveys. Earn Cash.
