Vala method names are usually lower case.

The same goes for List.sort(). strcmp is not in the Gtk namespace.

Can't help you on this one, sorry.

The following code works fine for me:

    using GLib;

    public class ListTest : GLib.Object {

        public static int main (string[] args) {

            List<string> list = new List<string> (); 

            list.append ("uno");
            list.append ("due");
            list.append ("tre");

            list.sort (strcmp);

            foreach (string item in list) {
                debug (item);
            }   

            return 0;
        }   
    }

Be aware, however, that it's been a while since I last coded in Vala.

Resistance is futile, you will be garbage collected.
