Re: [gtkmm] Customized CellRenderers

[Leandro Fanzone <leandro hasar com>]

Well, if nobody knows how to do this, at least can anybody tell me if 
someone is working on bug #102853, or if there is some workaround for 
it? I would do it myself, but I never could understand the always 
Kafka-esque TreeView not even from the user point of view, let alone the 
inner mechanics.
Thank you again,

Leandro Fanzone.
