Question about CellRendererSpin

[alanb]

Hi,

I have a CellRendererSpin ui component in my treeview. If possible I want to pick up the signal generated when the value in the spinbutton is changed and use it to dynamically alter a drawing based on the current value of the spinbutton. At present the drawing is changed when editing the value is complete as I have placed that code in the cell Edited signal handler. I cannot see how to attach a handler for the ValueChanged  signal on the spinbutton in the treeview. So can someone tell me how to  do this or even if its possible.

thanks

Alan
