Cannot pass enum value as signal parameter from C++ to QML

    XMLWordPrintable

    • f2219ce983098fc14655d8f3bb8a7fee2c9abe4d

    Description

      See attached file.

      When an ImageViewer::Status value is emitted from C++, it is received in the QML signal as a QVariant(ImageViewer::Status) value, instead of the actual enum value.

      The enum has already been registered using:

      • Q_ENUMS
      • Q_DECLARE_METATYPE (as ImageViewer::Status)
      • qRegisterMetaType (as ImageViewer::Status)
