Cut/copy/paste from window menu

["Alessandro 'supern3t'" <supern3t gmail com>]

Hello everybody!

I'm developing a simple gtk project. In my main window there is a
textview. I want to enable cut/copy/paste from window menu.
It already works using shortcourts like CTRL+X and so on, and from the
menu related to the right click, but I want to enable these features
from the self-created window menu.
There is a simple way to do it?
Thanks!!
