RegisteredWidget has been renamed to RegisteredWdg. This is a deprecated class, all that use it should be recoded and RegisteredWdg should be deleted as soon as possible.

The *new* RegisteredWidget is a template class and should be subclassed (eventually) from Gtk::Widget, for example RegisteredWidget<Scalar> will be subclassed from Scalar, which is subclassed from Labelled, => Gtk::HBox => Gtk::Widget. This way, a RegisteredWidget<T> can be directly used as Gtk::Widget, and gtk::manage works, etc! This all should solve the problem of having multiple widgets for the same parameters.
