Re: [gtkextra] Disabling middle mouse button paste in GtkSheet

[Adrian Feiguin <feiguin magnet fsu edu>]

You have to add a line:
  if(event->button == 2){ /* 2 for middle button */
   ...
  }

BTW I just bought Havoc's book at Border's for 6 bucks. I know it's freely
available on the web, but it could be handy to have a hard copy.
