I changed my code to read: g_snprintf(buf, sizeof(buf), "STRIKETHROUGH"); tag = gtk_text_tag_table_lookup( gtk_text_buffer_get_tag_table( text_buffer ), buf ); if (!tag) tag = gtk_text_buffer_create_tag( text_buffer, buf, "strikethrough-set", TRUE, "strikethrough", true, NULL ); gtk_text_buffer_apply_tag (text_buffer, tag, start, end); but still nothing. I will try to debug...
