SpinButtons as Cell renderers

[Brett Nash <nash nash nu>]

Hello,
        I'm trying to implement a Spin Button as a Cell Renderer in a 
Triew view column.  I was wondering if anyone had already done this in
an application, and could point me to the code (seedy is fine).  

        In either case is there any thought of this widget being made
standard for tree views?

        Regards,
        nash
