Re: Custom containers with Spirit X3 (QString)

And perhaps you will need some more traits to adapt the QString:

namespace boost { namespace spirit { namespace x3 { namespace traits {

// Adapt push_back for QString

template <>
struct push_back_container<QString>
{
    template <typename T>
    static bool call(QString& c, T&& val)
    {
        c.push_back(std::move(val));
        return true;
    }
};

// Adapt append for QString

template <>
struct append_container<QString>
{
    template <typename Iterator>
    static bool call(QString& c, Iterator first, Iterator last)
    {
    	// Implement a better append here...
    	c.append(QString::fromUtf8(&*first, std::distance(first, last)));
        return true;
    }
};

// Adapt empty for QString

template <>
struct is_empty_container<QString>
{
    static bool call(QString const& c)
    {
        return c.isEmpty();
    }
};

} } } }

Best regards,
Mike...
