Conceptually this is still a key/value "map". It doesn't matter if it is a tree or a hash map. This is an implementation detail.
The term "hash" usually means hash code or value and not hash map when used standalone.
If we want to reference the underlying data structure in the naming then inputDeviceMap.

QMultiHash is not a subclass of QHash in Qt6: https://doc.qt.io/qt-6/qtcore-changes-qt6.html#removal-of-qhash-insertmulti so the QHashIterator(const QHash<Key, T> &hash) constructor cannot be used with QMultiHash.
