Pass enum into QML and use it in JavaScript. How?

bogong

Hello!
I need to get enum from C++ into QML:

class SomeClass : public QObject {

	Q_OBJECT

	public:

		enum Types {
			Type0 = 0,
			Type1 = 1,
			Type2 = 2
		}; Q_ENUM(Types)
};

How to get it into QML and use it JavaScript?

class SomeClass : public QObject {

	Q_OBJECT
        Q_PROPERTY(Types  type READ type WRITE setType NOTIFY typeChanged) //<

	public:

		enum class Types  : int{  //<
			Type0 = 0,
			Type1 = 1,
			Type2 = 2
		}; Q_ENUM(Types)

   Types  type()const{
        return m_type;
    }
    void setType(const Types &t){
        if(m_type!=s){
            m_type=t;
            emit typeChanged(m_type);
        }
    }
signal : 
void typeChanged(Types t);

 private :
   Types m_type  = Type0; //<

}; 
Q_DECLARE_METATYPE(SomeClass::Types ) //<

//main.cpp

   SomeClass obj; // create class obj
   QQmlApplicationEngine engine;
   engine.rootContext()->setContextProperty("myObj",&obj); // make it known in QML


   qmlRegisterType<SomeClass>("com.my.comp", 1, 0, "SomeClass"); // register the enum

//qml js

import com.my.comp 1.0

..

 source : myObj.type === SomeClass.Type0 ? "/typeZeroImg/img.png" : "autherImg/img.png"
}

@LeLev said in Pass enum into QML and use it in JavaScript. How?:

Q_DECLARE_METATYPE(SomeClass::Types )

This forgotten for me. Thx. Issue closed.
And it's not working if it inside of Singletone class because of disabled default constructor.
