GtkD help

[Ivan Trombley via Digitalmars-d-learn]

I have this small application for viewing select log data from a 
certain game that I originally wrote in C++/Qt. For various 
reasons, I decided to rewrite this app in D using gtk-d. First, I 
have to say that the documentation for gtk-d is atrocious! 
However, I managed to cobble together enough information to get 
80% of it done.

I would like to be able to controll how the cells in a TreeView 
are rendered (ie the text color used) but I'm not able to find 
any information about how to do this. Does any one have 
experience here? If so, can you please give me a clue?
