tree view resize columns with hpaned change

[Wesley Smith <wesley hoke gmail com>]

Hi,
I'm trying to figure out the best way to adjust the spacing on a
GtkTreeView column when the view containing it is resized via a
GtkHpaned.  Is there a way to get a signal (either from the hpaned
itself or from the tree view as it changes) such that I can modify the
columns?  I have 4 columns, 3 are fixed.  I'd like the varying one to
be able to resize to fit the available space.  GtkTreeView does tihs
right now, but I want the far left column to adjust instead of the far
right as it does currently.

thanks,
wes
