Disable sort when adding row to GTkTreeSrore

["POULAIN DOMINIQUE (AREVA TA)" <DOMINIQUE POULAIN technicatome com>]

Hello,

 

I'm migrate my aplication from GTK 1.2 to 2.10. So I try to use
GtkTreeStore and GtkTreeView. The fist task is to show the file system
hierarchy (and I want to filter this list, but it will be a second
question). When the user choose to expand one directory, I must add a
lot of rows. To preserve times, i try to detach the model from the tree,
and to disable the sort. The result is that it goes faster but i got
this error message

 

Gtk_CRITICAL ** : gtk_tree_store_sort : assertion
tree_store->default_sort_func != NULL failed

 

Gtk_CRITICAL ** : gtk_tree_store_sort_iter_changed : assertion
tree_store->default_sort_func != NULL failed

 

 

Is there an other way to disable the sort ? 

 

Thank you
