      QHashIterator used to be able to iterate over QMultiHash.
      The documentation still states that it is possilbe:
      https://doc-snapshots.qt.io/qt6-dev/qhashiterator.html

      However, it is not possible any more, you get errors like:

      error: no matching function for call to ‘QHashIterator<QString, QwtPlotCurve*>::QHashIterator(QMultiHash<QString, QwtPlotCurve*>&)’

      Please either:
      a) Fix QHashIterator so that it is able to iterate over QMultiHash
      or
      b) Adapt documentation and provide guidance in https://doc.qt.io/qt-6/qtcore-changes-qt6.html how to adapt existing code.
