Maybe this will help, taken form

Preventing row selection

Maybe the user should not be able to select every item in your list or tree.
For instance, in the gtk-demo, you can select a demo to see the source code,
but it doesn't make any sense to select a demo category.

To control which rows can be selected, use the set_select_function() method,
providing a SigC::Slot callback. For instance:

m_refTreeSelection->set_select_function( SigC::slot(*this,
&DemoWindow::select_function) );

and then

bool DemoWindow::select_function(const Glib::RefPtr<Gtk::TreeModel>& model,
                                 const Gtk::TreeModel::Path& path, bool)
{
  const Gtk::TreeModel::iterator iter = model->get_iter(path);
  return iter->children().empty(); // only allow leaf nodes to be selected
}
