主要是参考《GTK+:“菜单” （menubar）和“工具栏”（toolbars）》

例子中的vbox = gtk_vbox_new(FALSE, 0);是属于gtk+2.0的，要改为vbox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 0);才能在gtk+3.0编译通过，原作者的讲解是比较容易理解，在此要感谢原作者
以下gtk+编程例子是来自书籍《实用技术：开发Linux应用——用GTK+和GDK开发Linux图形用户界面应用》第62页的内容——菜单，结合自己的理解，写了一个简单的小程序
粥 粉 面 饭 其它
白粥 螺蛳粉 牛腩面 叉烧饭 云吞
猪红粥 桂林米粉 兰州拉面 扬州炒饭 萝卜糕
八宝粥 肠粉 捞面 煲仔饭 粽
艇仔粥 汤粉 竹升面 蒸饭 油炸鬼
皮蛋瘦肉粥 炒粉 刀削面 竹筒饭 蛋塔
在openSUSE-Leap-15.3-DVD-x86_64的gnome3.34.7桌面环境下编译的，其中pkg-config --cflags --libs gtk±3.0两边有反引号括起来的

例子中的vbox = gtk_vbox_new(FALSE, 0);是属于gtk+2.0的，要改为vbox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 0);才能在gtk+3.0编译通过，原作者的讲解是比较容易理解，在此要感谢原作者，重新排版如下：
#includeint main( int argc, char *argv[]) { GtkWidget *window; GtkWidget *vbox; GtkWidget *menubar; GtkWidget *filemenu; GtkWidget *file; GtkWidget *quit; gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER); gtk_window_set_default_size(GTK_WINDOW(window), 250, 200); gtk_window_set_title(GTK_WINDOW(window), "menu"); g_signal_connect_swapped(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL); vbox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 0); gtk_container_add(GTK_CONTAINER(window), vbox); menubar = gtk_menu_bar_new(); gtk_box_pack_start(GTK_BOX(vbox), menubar, FALSE, FALSE, 3); file = gtk_menu_item_new_with_label("File"); gtk_menu_shell_append(GTK_MENU_SHELL(menubar), file); filemenu = gtk_menu_new(); gtk_menu_item_set_submenu(GTK_MENU_ITEM(file), filemenu); quit = gtk_menu_item_new_with_label("Quit"); gtk_menu_shell_append(GTK_MENU_SHELL(filemenu), quit); g_signal_connect(G_OBJECT(quit), "activate", G_CALLBACK(gtk_main_quit), NULL); gtk_widget_show_all(window); gtk_main(); return 0; }
