Hah, completely missed that. I'll have look at it.

I agree it is a bit unusual. But OTOH it doesn't really claim to be a
Gtk::Window. I personally feel uncomfortable inheriting from the
various widgets since I'm not sure of what I get. And so far, the only
things I've needed from other classes of the Gtk::Window interface is
show()/hide()/raise() and a window pointer for set_transient_for().

What do others do? It's part of the basic structure of a
libglademm-enabled application so it's important to get right.

Another option is to derive from Gtk::Window and then just load the
window contents from the XML. But then you need to put window layout
code in the constructor, though it doesn't amount to terribly much.
IIRC that's what you do with PrefixSuffix?
