Gtk::TreeView modify at runtime

[Jorge Villalobos Beato <tiusender gmail com>]

Hi to everybody!

I'm a newbie on Gtkmm, so maybe the answer to my question is obvius.
Anyway, this is is my problem: I want to update a TreeView that is
already visible in a window. I know how to modify it before doing
'm.run(*window1);'but not after. I will appreciate any help at this subject.

Thanks,
