[Gtk-sharp-list] Context menu

[Rampage]

Hello everyone :)
Does anyone have any sort of tutorial/example on how to implement 
context menus? like: right click on an item of a treeview and i get 
access to functions that are related to that specific item?

the simpliest the better, since i'm at the beginning with gtk# and gtk 
in general, i'm looking for something that even a monkey can understand :D

Best regards
Francesco
