QML使用C++定义枚举

枚举定义

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    enum FunType{
        RED = 1,
        YELLOW,
        BLUE
    };
    Q_ENUM(FunType)

    MainWindow(QWidget *parent = nullptr);
    ~MainWindow();
    Q_INVOKABLE void callFun(FunType funType);
protected:
    void resizeEvent(QResizeEvent* e) override;
private:
    void initQmlWidget();
private:
    Ui::MainWindow *ui;
    QQuickView* m_pQmlView = NULL;
    QQuickWidget* m_pQmlPanel = NULL;
    QQmlContext* m_pContext = NULL;
};

注册类型

注册枚举所在类

qmlRegisterType<MainWindow>("com.EnumTest.MainWindow", 1, 0, "MainWindow");

QML引用注册类

import com.EnumTest.MainWindow 1.0

QML中使用枚举

appMainWindow.callFun(MainWindow.RED);
