will QHash::remove call delete?

[jajdoo]

i have:

QHash<QString, polly::Element*> _children;
(polly::element being a class of my own)

i want to remove an item from the hash and be sure its dead - the internet has me confused about this one.. will remove call delete for me?

You're storing a pointer to polly::Element so you have to delete yourself.

just make a call like this to remove and delete


delete _childern.take(key);

EDIT: late response, nish answered

which one is the better option?
( element is also a QObject - just noticed that my QHash of children logically clashes with the QObject's having a children list already.. )


delete _children.take( name );

_children.value( name )->deleteLater();
_children.remove( name );

delete _children.value( name );
_children.remove( name );
