It's actually not necessary to declare them in the .h file. Just
create them with "Gtk::manage(new Gtk::SomeWidget(...))" and add to a
container. Using this method, only the toplevel widget needs to be
declared.

I guess someone didn't know how Gtk::manage works and assumed that
every widget has to be a member of the dialog's class, so it is
destroyed when the the dialog is closed.
