colour question

[ashley maher <ashley.maher@xxxxxxxxxxxxxxxxxxxx>]

G'day,

Trying to get my head around gtk2 I put together the code below from
examples in the gtktree tutorial and the colour example code I found in
the mailing list.
ie.

http://mail.gnome.org/archives/gtk-app-devel-list/2002-November/msg00249.html

It compiles, and runs.

Unfortunately it colours the entire background blue and all fonts are
white. Not just the right hand column as in the example and as I wanted.

Could somebody please point me to where I stuffed up in the code below,
and or where to get info to fix what I clearly have misunderstood.

And where can I find a reference for stippling the background of a cell?

Thanks in advance.

Regards,

Ashley
