background in gtk_text_view

[Michał Straszak <micstr poczta fm>]

Hello,
Is it possible to set the background color of the whole
line (or lines) in gtk_text_view? And how? (not text background)
My english isn't perfect, so this is what I mean:
|--------------|
|Some text     |
|Some#text#####| #-colored background
|              |
|Some#very#very|
|long#text#####|
|              |
|--------------|

TIA
Michal
