I'd prefer: Item { enum Weather { Raining, Sunny, Cloudy } property Weather weather: Weather.Sunny; } Since enum is already a reserved keyword in Ecmascript this should be doable without problems. If the enum is declared in a different context, the property declaration should IMO be OtherItem { property Bar.Weather weather: Bar.Weather.Sunny; } Cheers, Lars > > What should enumeration declarations in QML look like? > > -- > Alan Alpert > _______________________________________________ > Development mailing list > Development@qt-project.org > http://lists.qt-project.org/mailman/listinfo/development _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
