    Description

      The following code can produce a warning:

      QList<Bar> entries;

std::vector<Foo> values;

values.reserve(entries.size()); // warning

      You can silence the warning with:

      QList<Bar> entries;

std::vector<Foo> values;

values.reserve(static_cast<std::size_t>(entries.size())); // no warning but very verbose

      Adding usize() to Qt Container would improve the readability of the code:

      QList<Bar> entries;

std::vector<Foo> values;

values.reserve(entries.usize()); // warning
