Set up a foreach scenario for all selected items:

        GtkTreeSelection *selection = NULL;

        selection = gtk_tree_view_get_selection(view);
        gtk_tree_selection_foreach(selection, remove_cb, NULL);

then in the callback:

        void remove_cb(GtkTreeModel *model, GtkTreePath *path,
GtkTreeIter *iter, gpointer userdata)
        {
                GtkTreeStore *store = NULL;

                store = GTK_TREE_STORE(model);
                gtk_tree_store_remove(store, iter);
        }
