GtkTextBuffer *buffer;

buffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(text_view));
應(yīng)該是指針未初始化吧。

/*---------------------輸入文本的滾動(dòng)窗口------------------------------------*/
    Send_scrolled_win = gtk_scrolled_window_new(NULL,NULL);/*生成滾動(dòng)條的窗口*/
    gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW(Send_scrolled_win),text_view);
    gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(Send_scrolled_win),GTK_POLICY_AUTOMATIC,GTK_POLICY_AUTOMATIC);/*滾動(dòng)條屬性*/

出在這一句。你gtk_scrolled_window_add_with_viewport的時(shí)候，text_view還沒有生成，它還是個(gè)野指針呢！
