Thanks. I need an accurate list of children in response to a child's
destroyed signal, so is the best way to do this, then, to have Parent
maintain its own list of Children, rather than using findChildren(), and
use the destroyed(QObject*) version of the signal to explicitly remove the
Child from the Parents list?
