How to make a gtktreeview column flexible?

[Till Harbaum / Lists <lists harbaum org>]

Hi,

i have a gtktreeview filling the complete width of a window. Now i want the 
view to always use the full width. I therefore want the middle column (a text
column) to be flexible. I want it to be as wide as possible for any given window
width. So if you make the window wider i want this column to become wider.

If i just enable ellipsis in the columns text renderer the column gets very 
small and only a fraction of the window width is used. If i make it a fixed 
width it's exactly that: fixed width.

How do i make the column always use a much space as possible but never
more than available?
