No, if you are just removing a row from the child model or inserting one in it, there is no need for creating a new sort model. The child model will "notify" the sort model about these changes and the sort model will automatically update. > - About efficiency, everytime I set's the sortedModel to the GtkTreeView > it takes a few seconds (like 2 secs) to display it.

Setting a sort model that has already been connected to a filled child model on a GtkTreeView shouldn't take much time and basically be displayed instantly. If you first set the sort model on the GtkTreeView, then sort it and then fill the child model with nodes it might take a while since an expensive insertion sort will have to be done for every node that is inserted. regards, -kris. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
