[Vala] Gtk.TreeView + Cellrender + text different colors ???

[Flavio Danesse <fdanesse gmail com>]

Hello, to see if anyone knows how to do this ? I try pass this code python
to Vala:

self.get_model (). append ( _iter , [int (key) , text, color] )


The idea is that adding a new element in a treeview , you can specify a
particular color in that cellrender I tried a little of everything and
nothing seems to work
