A Question about GtkTreeSortable

[searun <searun gmail com>]

Hi ,

Now i want to use GtkTreeSortable to sort a list. The first entry in the
gtk_tree_view is an information entry which needn't to be sorted, so i don't
want the GtkTreeIterCompareFunc function use the first entry. In my programe
i check GtkTreeIter, if it is the same as the first iter, the
GtkTreeIterCompareFunc will return 0.
BUT it can't work. After two day's debug, i can't find the reason.

Any help is appreciated, even if you have another good method.

Thanks,
Jackie
