[Urwid] suggestion and guidelines

Hello Ian

I solved this! It was a stupid error, I was trying to make a list of a 
list!!!!

It work perfectly [if you did not know ;)]

The third point I also understood. But now I really need some help. As 
you can see from my attached code (sorry if it not clean, but I am 
really new on this python stuff), I create a class CUPSconsole where I 
created two empty (actually with one empty element) listboxes. I was 
expecting (again sorry if i going to say something really stupid) that 
when I call "update_readings()" function the listbox contents should be 
updated. But nothing happens. What am I doing wrong? What have I missed?

Thanks for all the trouble Ian, and for such nice package.
Pedro
