The \c PieChart type currently has a string-type property and a color-type property. It could have many other types of properties. For example, it could have an -enum-type property to store a display mode for each chart: +int-type property to store an identifier for each chart: \code // C++ class PieChart : public QDeclarativeItem { - Q_ENUMS(DisplayMode) - Q_PROPERTY(DisplayMode displayMode READ displayMode WRITE setDisplayMode) + Q_PROPERTY(int chartId READ chartId WRITE setChartId NOTIFY chartIdChanged) ... public: - enum DisplayMode { - MultiLevel, - Exploded, - ThreeDimensional - }; - - void setDisplayMode(DisplayMode mode); - DisplayMode displayMode() const; + void setChartId(int chartId); + int chartId() const; ... + + signals: + void chartIdChanged(); }; // QML PieChart { ... - displayMode: PieChart.Exploded + chartId: 100 } \endcode |
