Thanks. But that wouldn't involve a std::unique_ptr<> at all. It
doesn't feel much different than what we have with Gtk::manage().
It also forces the add() to to the beginning. I tend to prefer doing
that at the end, after setting up the child widget. I generally assume
that changing the state of the child after it is in a container might
trigger useless processing which I could avoid by doing it before
adding it to the container.
Allowing use of unique_ptr<> seems more flexible.
