Re: [Vala] Access the "klass" parameter of a class_init() function in vala with "static construct"

Hi,
I see you've found a solution. But see my comments below about the
"right thing".

It should be a *class* variable, not an instance variable. So try
something like
        protected class GLib.Type toolbar_item_type;
and you won't be able to access it from static construct AFAIK, you need
to use class construct.
