QML singleton in CMake (Qt 6.2)

[paulmasri]

In the documentation for Qt 6.2+, it gives an example of how to create a singleton: https://doc.qt.io/qt-6/qt-target-qml-sources.html

The CMake code:

set_source_files_properties(FunnySingleton.qml PROPERTIES
    QT_QML_SINGLETON_TYPE TRUE
)

results in qmldir:

singleton FunnySingleton 2.0 FunnySingleton.qml

How could I get it to put the following in qmldir instead:

singleton FS 2.0 FunnySingleton.qml

i.e. how do I rename it so that I can reference its properties elsewhere in QML as FS.xxx instead of FunnySingleton.xxx?

https://doc.qt.io/qt-6/qt-target-qml-sources.html says:

the name of the type itself can also be overridden using the QT_QML_SOURCE_TYPENAME property.

so writing should achieve what you want:

set_source_files_properties(FunnySingleton.qml PROPERTIES
    QT_QML_SOURCE_TYPENAME FS
    QT_QML_SINGLETON_TYPE TRUE
)

QT_QML_SOURCE_TYPENAME

Thanks. I really should learn to read. It was in the same paragraph as QT_QML_SINGLETON_TYPE. 🤦
