To avoid calling a virtual method on an object (rParent) where rParent
hasn't finished its construction yet so virtual methods don't work yet,
the spell-check dialog has a hack to use postuserevent and finish the
initialization later.

Part of the initialization is run first though, and the list of
languages to populate the add menu is generated before the second part
of initialization is run which determines the languages available.
