qDeleteAll() and linked list iterators

[Vit Stepanek]

What are you trying to do exactly?
Do you want to make it use qDeleteAll, or what?

By the way, the implementation of the "node" struct is very confusing. The item given to be stored is copied in the ctor using shallow copy, but then you delete it in the dtor like it were a deep copy. This will lead to troubles.

I just threw that together real quick. That should be a pointer to the stored value, rather than a shallow copy (looking for edit button).

What it's supposed to demonstrate is a valid STL iterator that requires the dereferenced value of the iterator to increment. qDeleteAll(...) deletes the dereferenced value before iterating. Resulting in a memory access error on iteration.
