 So, we need to check exactly what is the refcount of the vbox _before_
 it is destroyed in the C example, and before it is destroyed in the
 C++ example. Maybe we just need to do an extra unref before destroying
 it - but we need to check that first.

+
+Yes, and that's probably not necessary. But removing it gives us this
+error, as you found:
+
+  (main:16157): Gtk-WARNING **: A floating object was finalized.
+  This means that someone called g_object_unref() on an object
+  that had only a floating reference; the initial floating
+  reference is not owned by anyone and must be removed with
+  gtk_object_sink() after a normal reference
+  is obtained with g_object_ref().
+
+I am currently investigating why this happens. As far as I can tell,
+after removing that ref from _init_unmanage(), gtkmm never refs or
+derefs the vbox.
+
+I also noticed that _init_unmanage() sets _referenced always, but it
+should be false for widgets with Glib::wrap(). But fixing it does not
+seem to make a difference.

+As i said earlier i'm talking only about documentation which available
+online from http://gtkmm.org/gtkmm2/docs/ If there is better way,
+please tell me.
+
+first of all i can't find within online documentation which version of
+gtkmm it relates to. With so much debates on incompatible library
+versions it seems necessary to look for.
+
+Also please take a look here: 
+http://gtkmm.org/gtkmm2/docs/reference/html/classGtk_1_1Widget.html#a82
+and here
+http://gtkmm.org/gtkmm2/docs/reference/html/classGtk_1_1Widget.html#a83
+and here
+http://gtkmm.org/gtkmm2/docs/reference/html/classGtk_1_1Widget.html#a85
+and here
+http://gtkmm.org/gtkmm2/docs/reference/html/classGtk_1_1Widget.html#a86
+
+This is what you call bug in documentation. 
+
+Also i can't find any suitable overloads for this methods.
+
+Please grep you documentation sources for " or 0 to " and you will see
+all of them.
+
