[pygtk] Adding Validation in TreeView: how to use 'edited' cb and stop any other processing?

[Alessandro Dentella]

Hi,

   I'm trying to add validation in a TreeView. 

   Connecting to cell's 'edited'  signal I can trigger validation on a cell
   input and if the field is not valid I reset it to previous value. That's
   not ideal, since the invalid value must be completely reentered while I'd
   like to leave it there.

   really It's pretty easy to do exacly what I want trapping a Tab on the
   editable, but that's junst *one* way to travel throught data (albeith
   very common).
   
   What I was not able to do is to prevent from moving from that cell, from
   within the 'edited' callback. I don't know how to stop any further
   processing of possible precedent events (click on other cell or DonwArrow
   or Tab...)

   Any hints?

   TIA
