QRangeModel::ItemAccess Struct
template <typename T> struct QRangeModel::ItemAccessThe ItemAccess template provides a customization point to control how QRangeModel accesses role data of individual items. More...
This struct was introduced in Qt 6.11.
Detailed Description
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.
