problems with new class

["Oskar Liljeblad" <osk hem passagen se>]

I've written a new class, whose parent is GtkObject. Whenever I try to
create a new instance of it with the myobject_new function, I get this
error:

** WARNING **: invalid unclassed pointer in cast to `MyObject`

(Other errors follows, such as 'invalid class type `(unknown)` in cast to
`GtkObject`.) The object has been successfully allocated a unique type with
gtk_type_unique(gtk_object_get_type(), ...), the class initialized and the
object itself initialized. It fails when MYOBJECT() is issued:

MyObject *myobject_new(void)
{
  return MYOBJECT(gtk_type_new(myobject_get_type()));
}

MYOBJECT() is defined as

#define MYOBJECT(obj) (GTK_CHECK_CAST ((obj), myobject_get_type(),
MyObject))

I've copied almost all code from other classes - and no warnings or errors
are reported during compiling. It's possible I've missed something, though.

I'm running GTK+ 1.0.4.
