right justifying tree view column data

[Christian Hansen <crushian speakeasy net>]

Hello,

I would like to right-justify a column of numeric data in a GtkTreeView 
and would appreciate any help.

I have tried using a GtkCellRendererText to render the values and have 
attempted to set the "alignment" property to PANGO_ALIGN_RIGHT without 
success using 2.10.  I would also like to know if there is an easy way 
to do this using 2.8.

Thanks,
Christian
