Re: Showing the value in a GtkTreeViewColumn depending on a condition

["Shahms E. King" <shahms shahms com>]

You don't do it on a per-column basis, but on a per-render basis and
there are a number of ways to do that. The easiest and most
straightforward is to have a column in your GtkTreeStore (assuming
you're using this and not writing your own) something along the lines of
"IS_ROOT" with a type of G_TYPE_BOOLEAN that you assign to the "visible"
property of the GtkCellRenderer you want to hide.  Then, when you insert
your data, just make sure that column is set appropriately and it will
work.  The other way to do it is using _set_cell_data_func () on the
cell renderer and doing everyting that way.
