That cast is actually a very good thing. You can write dialogs that
return custom response types. the Run method returning an integer allows
this to work easily. The other way would work as well (returning as
ResponseType, casting to int if needed) as long as the gtk# GEnum
marshalling can handle it (I believe it can).

Do you mean the GtkDemo? Available in the samples/GtkDemo/ directory of
gtk#. Or is this a separate tutorial. If so, please send the url to the
list, and if I get a chance, maybe I will translate it.
