you can use gtk_tree_view_set_cursor() and gtk_tree_view_get_cursor().
I store the row number in my model for easy reference.

GtkTreePath *path;
GtkTreeViewColumn *column;
glong column_ix,row_ix;

gtk_tree_view_get_cursor(treeview,&path,&column);
if(path && column) {
  GtkTreeIter iter;

  if(gtk_tree_model_get_iter(treestore),&iter,path)) {
    GList *columns=gtk_tree_view_get_columns(treeview);

    column_ix=g_list_index(columns,(gpointer)column)-1;
    g_list_free(columns);
    gtk_tree_model_get(treestore,&iter,TABLE_POS,&row_ix,-1);
  }
}
if(path) gtk_tree_path_free(path);

printf("cursor at col/row = %d,%d\n",column_ix,row_ix);
