Hello everybody!

When I open the .glade file using libglademm's Gnome::Glade::Xml::create
i get the following error msg:

(lsd:25591): libglade-WARNING **: unknown widget class
'GtkFileChooserDialog'

I have designed the interface using Glade, and added some file dialog to
open and save files (unsurprisingly).

I'm thinking this is a matter of version numbers, and changed class
names (maybe GtkFileChooserDialog was/is known as GtkFileSelection or
something).

I use (and abuse):

gtkmm-2.2.12
libglademm-2.0.1
glade-2.6.7

What can I do? This is my first project using glade, gtkmm and
libglademm and i'm a bit lost.


Salud.
