Detailed Description

template<typename T>
class QRangeModel::ItemAccess< T >

\inmodule QtCore

The ItemAccess template provides a customization point to control how QRangeModel accesses role data of individual items.

Since

6.11

ItemAccess<T> is a struct template where T specifies the item type. Specialize this template for the type used in your data structure, and implement the relevant class member functions.

template <>
struct QRangeModel::ItemAccess<ColorEntry>
{

    static Qt::ItemFlags flags(const ColorEntry &entry)
    {
        return entry.flags();
    }

    static QVariant readRole(const ColorEntry &entry, int role)
    {
        switch (role) {
            // ...
        }
        return {};
    }

    static bool writeRole(ColorEntry &entry, const QVariant &value, int role)
    {
        bool ok = false;
        switch (role) {
            // ...
        }
        return ok;
    }

\dots

};

A specialization of this type will take precedence over any predefined behavior, and over a corresponding specialization of \l{QRangeModel::}{RowOptions}.

Note

Do not specialize this template for types you do not own.
