Re: Gtk::TreeView

["Paul Davis" <pjdavis engineering uiowa edu>]

Vladimir,

I've attached two files. They're both essentially the same thing that
you pasted, but changed a bit to make them compile without the rest of
your code.

Try compiling and running them and let me know if they produce the
errors you're getting with your code.

better.cc is the same program implemented slightly differently using
stack allocation and inheritance. Both being 'Good Things (TM)' in
this case.
