I realise you've done this example off the top of your head but do you 
know of any working examples?

As far as I can see I have to do something like:

    Gtk.Application.Invoke(this, msg, AppendAValue);

but it won't compile because msg isn't the right type (EventArgs).

Unfortunately the example in the Mono docs 
doesn't actually show how to do this...
