QtScript is deprecated and not available in Qt6 I tried porting the scripting to QJSEngine, but found two issues: - QJSEngine doesn't have a debugger interface like QtScript has: https://bugreports.qt.io/browse/QTBUG-55905 - QJSEngine doesn't support dynamic properties: https://doc.qt.io/qt-6/qjsengine.html#dynamic-qobject-properties
