12      \brief Base type for the \l SortFilterProxyModel proxy roles defining a single role.
13  
14      SingleRole is a convenience base class for proxy roles who define a single role.
15      It cannot be used directly in a QML file.
16      It exists to provide a set of common properties and methods,
17      available across all the other proxy role types that inherit from it.
18      Attempting to use the SingleRole type directly will result in an error.
