Check if an iterator is valid for a QT container

Does any trick exist how to check whether an iterator (STL or Java style) is still valid for QMap or QList?

Thank you in advance.

No. The whole point of iterators is that they are independent of any containers. It is up to you to ensure that you only mutate a container if nobody else still has any iterators or references to the container's elements (subject to the container's iterator/reference invalidation specification).
