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

Specialize this template for the type used in your data structure, and implement {readRole()} and {writeRole()} members to access the role- specific data of your type.

template <>
struct QRangeModel::ItemAccess<ItemType>
{
    static QVariant readRole(const ItemType &item, int role)
    {
        switch (role) {
            // ...
        }
        return {};
    }
 
    static bool writeRole(ItemType &item, const QVariant &data, int role)
    {
        bool ok = false;
        switch (role) {
            // ...
        }
 
        return ok;
    }
};

A specialization of this type will take precedence over any predefined behavior. Do not specialize this template for types you do not own.
