Hi Yu,

the base keyword will chain the function call to the parent
class (which in this case is a GLib.Object) and not to any implemented
interface.

If you want to call the Iface.function member just use a cast like:

public void function() {
       message("class do something");

       ((Iface) this).function ();
}


Regards,

Interesting - I suppose this works because the function is not virtual?
