gtk and color in a GtkTextview

[exhortae <exhortae hotmail com>]

Hi,

First of all sorry for my bad english .

I would like to know how I can color text entered in a GtkTextView (in real
time), let me explain.

first when the user enter text it is displayed normally, then if my lexer
recognize the text, I want to be able to color it, I have the lexer, the
problem is with the coloring. This is what I have done as a start in
coloring fonts but it doesn't work. Can someone please tell me what am I
missing. 

thank you
