Have you tried with a QVariantMap for your Q_PROPERTY instead? Will be dull to convert from QVAriant to list and string for each values, but will probably work.

This data is being emitted via a signal. The registration is connected correctly as other components work just fine, though they're emitting only a single int or QString. An example of what I'm attempting is below: class Demo : QObject { Q_OBJECT public: Q_PROPERTY( QMap<QString, QStringList> mappings MEMBER mappings_ NOTIFY mappingsChanged ) }; What I'm expecting is that mappings would be transformed on the JavaScript side as: mappings { "key" : ["abc", "def"]... } However, when I try to view the data in the emitted signal it's always null. Any suggestions where I should look for more answers or perhaps I'm going in an incorrect direction? Thanks, -- John Schneiderman Senior Software Engineer CDPR Squad GOG.com
