MDI утечка памяти, Помогите разобратся с памятью... Опции

[fortero]

Доброе время суток, Господа!
Вопрос у меня есть к спецам QT, я сильно начинающий, поправьте если я что-то не так понимаю или скажу.
Я пишу программу с использованием дочерних ока MDI. За основу я взял код автора книги, в посте я приведу. Но меня мучают сомнения по поводу утечки памяти! Как вообще правильно отслеживать утечку памяти когда не уверен в коде???
При помощи диспетчера задач?
Или есть более правильный метод???
Вот код, взгляните правильно он написан, память высвобождается при закрытии дочерних окон?
Там есть опция:
setAttribute(Qt::WA_DeleteOnClose);
Теоретически должно работать, но у меня есть сомнения. В этом примере дочернее окно используется для создания текстового документа. А в моём случае там ещё банда виджетов! Таблица панели управления. Но если этот код правильный, то вся банда виджетов если унаследовала от родителя то при закрытии дочернего окна они освободят память, верно?
Код:
