some questions, please help

[Luka Napotnik <luka napotnik gmail com>]

Hi. I have two questions:

1. How can I determine a treeview column which will GTK+'s search
feature (that box that appears when starting to type) search for.

2. In the treeview tutorial
(http://scentric.net/tutorial/sec-treeview-col-whole-row.html), there's
a way to color a row by making a column connection to the 'foreground'
property. I don't understand how to connect that signal to a column?

Please help.

Greets,
Luka
