Maps role numbers and names of the attached model. This type was introduced in Qt 6.0. More...
- Import Statement: import org.kde.kitemmodels
- Since: Qt 6.0
Detailed Description
Attach KRoleNames to a model to map from roles to role names and vice-versa. It can be used to retrieve data from a model in an imperative fashion when a role enum is not available in QML (for example, when it is not exported via Q_ENUM) but role names are known; or to maintain consistency with view delegates (which use role names as properties).
