Glib::Param::GType − Wrapper for type parameters in GLib
This object describes a parameter which holds the name of a class known to the GLib type system. The name of the class is considered to be the common ancestor for valid values. To create a param that allows any type name, specify "undef" for the package name. Beware, however, that although we say "any type name", this actually refers to any type registered with Glib; normal Perl packages will not work.
undef = $pspec_gtype−>get_is_a_type
If "undef", then any class is allowed.
