Sounds easy enough. Want to give it a try?
Note that this should also work for foreach:
foreach (const auto i, qtEnumerate(map))
Something like:
template <typename Map>
struct QEnumerateMap : private Map
{
struct const_iterator {
typename Map::iterator i;
iterator(typename Map::iterator i) : i(i) {}
// need to return by value
std::pair<typename Map::key_type, typename Map::value_type>
value() const
{ return std::make_pair(i.key(), i.value()); }
};
const_iterator begin() const
{ return iterator(Map::begin()); }
const_iterator end() const
{ return iterator(Map::end()); }
};
