Model item cleanup?

[jsshapiro]

When a model item is added to a model, does the model "own" the item for deletion purposes?

Which model items are you talking about?

[jsshapiro]

For example, when I add a StandardModelItem to a StandardModel. Who is later responsible for deleting the StandardModelItem?

[dangelog]

The model you added it into.

QStandardItemModel::~QStandardItemModel ()

Destructs the model. The model destroys all its items.

Thanks. Sorry - I should have read more carefully.

Caution! The model does not always delete the items!

If you use one of the takeXX methods, like "QStandardItemModel::takeItem() ":http://doc.qt.nokia.com/4.7/qstandarditemmodel.html#takeItem, the item is removed from the model, but it is not deleted! You get back a pointer (or a list of pointers) to the item(s) and you can reinsert the item in the same or another model or you must delete it manually to avoid a memory leak.
