The callback passes the notebook page as a parameter, so you simply 
close the page.  It all works nicely.  Haven't looked at this area of my 
code for at least a year, so can only give basic overview and my 
recollection may be wrong.

As the whole tab may not be visible if several pages are open , most 
users will select a page prior to closing it. ( if only to make sure 
they dont close a page they need...  guess this depends on application 
and how much text is in your tabs)

I assume you are hand coding rather than using an IDE, so use the full 
power of GTK, rather than what the IDE gives you
