signals in simplelist - editable fields

[David Sword <gdsword williamsword co uk>]

Hi
I am using a simplelist with a column set to be editable (type double).
I can correctly pick up the values, using the changed signal, when the
user clicks on another row.  However, when they merely enter a new value
and press return, the selection doesn't move so there is no changed
signal (obviously).

I still need to handle a changed signal, but how do I combine with
another signal which will allow me to detect a value being entered,
and/or even be able to restrict entry to numeric characters. 

I know this is pretty basic stuff, but as a relative beginner to objects
and gui stuff, I am struggling to make this bit make sense, and would be
very grateful for any help that anyone can give.

Can I also say a big thanks to Muppet, Ross, and the rest of you guys
who have made Gtk2-perl happen.  I am writing software that I never
imagined would be possible for me to do, and so simply that it is
incredible!
