Here is my complete C code: http://www.ssalewski.de/tmp/test.c I inserted these lines: void on_row_inserted(GtkTreeModel *tree_model, GtkTreePath *path, GtkTreeIter *iter, gpointer user_data) { char *value; printf("row_inserted\n"); gtk_tree_model_get(tree_model, iter, LIST_ITEM, &value, -1); g_printf("value = %s\n", value); gint *i = gtk_tree_path_get_indices(path); g_printf("row ins = %d\n", i[0]); } void on_row_deleted(GtkTreeModel *tree_model, GtkTreePath *path, gpointer user_data) { printf("row_deleted\n"); gint *i = gtk_tree_path_get_indices(path); g_printf("row del = %d\n", i[0]); } First question: When I exchange rows by drag and drop, I get value = (null) similar to my test from Ruby yesterday. Is this intended, or is my code wrong (I have not much practice with using GTK from plain C...) Second question: I get row numbers when I exchange rows -- is there an easy way to map that numbers to the exchanged rows? Some glue logic seems to be necessary, i.e. for inserting: When I move upwards, the number is the final row number, but when I move downwards it is row + 1?
