I've just run into this problem (using pygtk).
I'd like to have a liststore that is both sortable and filterable.
In fact, I had such a beast, but I was using my own nasty hacks to
implement the filtering. I've had on my to-do list to switch to the
TreeModelFilter + I've just tried that -- unfortunately it seems I can
either have filtering or sorting, but not both.
Am I missing some trick?

TreeFilterModel and sorting
Hi,
we use GtkTreeModelFilter to filter a modell to diff.
views. Ok it
works. But we can't sorting the view because the model
in dthe view is
not a SORTABLE.
In function:
gboolean
gtk_tree_sortable_get_sort_column_id (GtkTreeSortable
*sortable,
gint
*sort_column_id,
GtkSortType
*order)
{
GtkTreeSortableIface *iface;
g_return_val_if_fail (GTK_IS_TREE_SORTABLE
(sortable), FALSE);
from gtk_tree_column_sort:
has_sort_column =
gtk_tree_sortable_get_sort_column_id
(GTK_TREE_SORTABLE
(GTK_TREE_VIEW
(tree_column->tree_view)->priv->model),
&sort_column_id,
&order);
we get the error message:
Gtk-CRITICAL **: file gtktreesortable.c: line 108
(gtk_tree_sortable_get_sort_column_id): assertion
`GTK_IS_TREE_SORTABLE
(sortable)' failed
Is it not possible to sort a view with FilterModel?
Or have me make a failure in bilding the view?
MfG Bernd
