Re: [Vala] problem with Object.get_class()

Hello,

I thought I've already answered this, but maybe I forgot.

It should and it does in my tests :-)

The problem is that calling g_type_class_ref on the returned ObjectClass
returns null. I don't know exactly why, but I see the warning at C
compilation as a hint that there may be a bug in the bindings: why
g_type_class_ref is the ref function of GLib.TypeClass, when the former
is supposed to take a GType as a parameter.

Anyway, here is my answer, I found it in the drafts folder:

I consider this to be a hack (and it may cause you trouble). I think you
should either use

unowned ObjectClass objectClass = t1.get_class();

if you have an object, or

ObjectClass objectClass = t.class_ref();
