Forum: Ruby-Gnome 2 Gtk::Builder can't handle new Gtk::Box definition

Hi everyone,
 
   it seems that the new version of Glade generates files in which 
Gtk::VBox and Gtk::HBox are replaced by a standard Gtk::Box with an 
orientation (vertical or horizontal) property.
This seemingly breaks Gtk::Builder. An example follows:(interface 
definition, testib.glade)
 
<?xml version="1.0" encoding="UTF-8"?><interface>  <!-- 
interface-requires gtk+ 3.0 -->  <object class="GtkWindow" 
id="window1">    <property name="can_focus">False</property>    
<child>      <object class="GtkBox" id="box1">        <property 
name="visible">True</property>        <property 
name="can_focus">False</property>        <property 
name="orientation">vertical</property>        <child>          
<placeholder/>        </child>        <child>          
<placeholder/>        </child>        <child>          
<placeholder/>        </child>      </object>    </child>  
</object></interface>
(test program)--require 'gtk2'
 
builder = Gtk::Builder.newbuilder.add_from_file("testib.glade")
 
objects = builder.objectsobjects.first.toplevel.show
 
Gtk.main
--This results in a segfault. If "GtkBox" in the glade file is replaced 
with "GtkVBox" everything works as expected.
 
The error message is GLib-GObject-WARNING **:cannot create instance of 
abstract (non-instantiatable) type `GtkBox'My guess is that builder 
tries to instantiate Gtk::Box (which is abstract) instead of the correct 
VBox or HBox. How can I fix this? I've tried to take a look at the 
source but I can't find anything of use...

Yes. This has been discussed a few months ago :
http://www.ruby-forum.com/topic/2385140

conclusion : use glade 3.8
