How to remove QObject from parent

Question

How can I break parent-child ownership for a QObject? It seems that there is no longer an explicit way of doing this. Is it enough to call

QObject::setParent(NULL)

Answer 1

You're correct. To make a QObject an orphan, simply do

// on C++11 compiler
object->setParent(nullptr); 

// on a pre-C++11 compiler
object->setParent(0);

Answer 2

According to the Qt5 Doc

You can also delete child objects yourself, and they will remove themselves from their parents.
