Re: Re: Invalid TextBuffer iterator

["Dmitry Kruglov" <lsd secy biz>]

Hello.

This example:

Gtk::TextView* p_text_edit = 0;
Glib::RefPtr<Gtk::TextBuffer> p_tb_result;

p_tb_result = Gtk::TextBuffer::create();
p_tb_result->set_text("Hello ch01 cout gmail com");
p_text_edit->set_buffer(p_tb_result);

Best Regdrs, Dmitry.
