<![CDATA[Prevent Destruction of QList<QTreeWidgetItem *>]]>I'm creating a QList<QTreeWidgetItem *> which holds an INI-backed list of virtual files and folders specified by the end user.

The problem is that because the items from the QList are associated with a QTreeWidget when presented to the user, they are also destroyed when the QTreeWidget is destroyed.

Is there any way I can stop this happening?

I have looked into using a QTreeView but the implementation seems to be pretty horrible and would prefer using the QTreeWidget if it is possible.

Unfortunately this doesn't work - the items are still munched up by the QTreeWidget.

I guess I'm just going to have to bite the bullet and figure out how to use a QTreeView.

in the destructor of your QTreeWidget call takeChildren that should take all items from the widget and return it as a list.
You can ignore the returned list, as you have one in memory already.

This is untested, I'm not 100% sure the TreeWidget won't still delete the items.
