Re: [Vala] question

[Flavio Danesse <fdanesse gmail com>]

Yes, I've read the tutorial, I'm slowly reading and trying.
In fact my application is already running, but surely not the best code for
vala and many details are not working.

For example, as I express this python code in vala?:

         self.inplay.get_children items = ()

         for item in items:
             if item.tipo == "Player":
                 item.stop ()
                 self.inplay.remove (item)
                 item.destroy ()

This does not work:

         var items = this.inplay.get_children();

         foreach (var item in items) {
             if (item.tipo == "Player") {
                 item.player.stop ();
                 this.inplay.remove (item);
                 item.destroy ();
             }
         }
