gnome下,当添加右键菜单后如何对菜单置灰

通过将menuitem的属性sensitive设定为false,可实现菜单得置灰处理

参考代码如下:

1 NautilusMenuItem* menulala = nautilus_menu_item_new (...);  //new 一个新的menu item
2 //add start
3 GValue sensitive = G_VALUE_INIT;
4 g_value_init (&sensitive, G_TYPE_BOOLEAN);
5 g_value_set_boolean (&sensitive, FALSE);    //设定sensitive的值为false,默认为true
6 g_object_set_property (G_OBJECT(menulala), "sensitive", &sensitive);
7 //add end
