Allow using enums as properties in QML

    XMLWordPrintable

Details

    Description

      It seems that enums which are exported from C++ can not be used as properties in QML.

      Consider the following example:

      C++:

      class Bar : public QObject
{
  Q_OBJECT
  QML_ELEMENT
  public:
    enum Weather { Raining, Sunny, Cloudy }
    Q_ENUM(Weather)
};

      QML:

      Item {
  property Bar.Weather weather: Bar.Sunny
}

      This doesn't work because we don't allow enums to be used as types in QML.

      It would be nice if exported enums just worked as properties. A workaround is to use "int" as the property type instead.
