Hi Thomas

As you say, "not very elegant"

Recently using pyGtk, hard coding, rather than using IDE.  Having used 
GTK with C in the past, I find pyGtk easier to use than C, but maybe a 
little less powerful.  (Could also be that I am learning Python which is 
generally faster to code than C).  It would be going off topic to 
mention more about pyGtk being less powerful, and maybe I am wrong 
because I have problems with Tables which I dont use in my C based 
code...  i.e they might not work as I expect in GTK with C either, so 
there is no difference

In C  your clicked signal can pass the notebook instance back to the 
click handler.  Assume the same can be done with pyGtk, but have not 
used notebooks with pyGtk yet
