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.

Subject: [Interest] Send Data to JavaScript
I'm attempting to send data to the JavaScript side of the QWebEngine
code. 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,
