Re: Gtk::TreeView

[Robert Caryl <bob fis-cal com>]

I was wrong when I said that Gnome::Glade::XML::get_widget does not
return a pointer to the requested widget.  It does indeed return that
pointer, but only if it succeeds.  It returns a NULL otherwise, so if
your call to delete the Gtk::Window obtained from get_widget crashes,
then it probably didn't return a valid pointer in the first place.

My apologies.
