QML中使用C++的枚举类型

C++头文件定义枚举类型

class Gemini:public QObject{ Q_OBJECT Q_ENUMS(BALL_COLOR) public: Gemini():m_ballColor(BALL_COLOR_YELLOW){ qDebug()<<"Gemini::Gemini() called"; } enum BALL_COLOR{ BALL_COLOR_YELLOW, BALL_COLOR_RED, BALL_COLOR_ALL, } signals: void begin(); public slots: void doSomething(BALL_COLOR ballColor){ qDebug()<<"Gemini::doSomething() called with"<<ballColor; if(ballcolor!=m_ballColor){ m_ballColor=ballColor; qDebug()<<"ball color changed"; } } private: BALL_COLOR m_ballColor; }

//在main.qml中

import Union.Lotto.Gemini 1.0 Window{ visible:true; width:300;height:400; title:"Union Lotto Game" color:"white" MouseArea{ anchors.fill:parent onclicked:{ gemini.begin() } } Gemini{ id:gemini; //参数类型是BALL_COLOR枚举 //QML中使用C++的枚举属性 onBegin:doSomething(Gemini.BALL_COLOR_RED) } }
