QT_QML_SINGLETON_TYPE

Marks a QML file as providing a singleton type.

This property was introduced in Qt 6.2.

A .qml file that provides a singleton type needs to have its QT_QML_SINGLETON_TYPE source property set to TRUE to ensure that the singleton command is written into the qmldir file. This must be done in addition to the QML file containing the pragma Singleton statement. The source property must be set before creating the module the singleton belongs to.

See qt_target_qml_sources() for an example on how to set the QT_QML_SINGLETON_TYPE property.
