I am actually not sure we need to invalidate at all when inserting items, unless you want to shuffle every time that happens? Perhaps all we need to do is shrink/grow the random vector when new items are added? > slidefiltermodel.cpp:121 > +{ > + m_randomOrder.resize(sourceModel()->rowCount()); > + std::iota(m_randomOrder.begin(), m_randomOrder.end(), 0); Can `sourceModel()` be null here?
