The size of an array has to be compile-time computable. This is either a constant or might be a `constexpr`. `QList::count()` is not qualified `constexpr`. – Scheff's Cat Apr 27 '21 at 14:17
Did you really intend to declare an array of `QList`s? You may try a `QVector` instead of the array: `QVector> zhiwus(zhiwuitemlist.count());`. – Scheff's Cat Apr 27 '21 at 14:20
