RefPtr is not meant to be a general-purpose smartpointer. I don't
recommend using it with Widgets.
Unless I've completely misunderstood the entire memory managemeny scheme
used by Gtk, once you call Gtk::manage(), you release all control of
memory management to the library. In other words, explicitly calling a
widget's destructor ( or implicitly via smart pointer reference counting
) would be 'bad'. I say 'bad' cause I'm not really sure what you'd run
into. I imagine you'd start getting things like memory corruption
errors or those fun messages about freeing the same memory segment
multiple times. Anyway, thats just how I had understood things.

manage() makes the container responsible for deleting the widget so it
would not be usefull in a case where you temporarily want to remove the
widget from its container.
That is a case where you have to delete manually or use a smartpointer.
