Sorry for this, evolution seems to play tricks on me ;)

Your question on calling delete or not isn't C++ specific, but framework
specific. If you want this framework, Gtkmm , to manage your heap object
you write:

foo* foo_ptr = Gtk::manage(new foo() );
bar_container->add(*foo_ptr);

When bar_container is destroyed the object foo_ptr pointed to will be
destroyed too. If you just do

foo* foo_ptr = new foo() ;
bar_container->add(*foo_ptr);

you have to save foo_ptr and call delete on it before your app ends.
