How to specify argument in CREATE_FUNC in Coco2d-x

Question

My MessageBoxes class has an argument passed in the constructor, I hope to know how can I specify the argument, which is std::string _content in this context, in the CREATE_FUNC()?

The error I get says "constructors cannot be declared 'static'"

This is the code of MessageBoxes.h:

class MessageBoxes : public cocos2d::Node
{
    private:
        Sprite* _sprite;
        bool _speaking;
        float _speakingTime;
        std::string _content;
    public:
        CREATE_FUNC(MessageBoxes(std::string content)); 

    protected:
        virtual bool init(std::string _content);
        void setSprite();
        void setContent();
};

CREATE_FUNC is a predefined macros defined in CCPlatformMacros.h

#define CREATE_FUNC(__TYPE__) \
static __TYPE__* create() \
{ \
    __TYPE__ *pRet = new(std::nothrow) __TYPE__(); \
    if (pRet && pRet->init()) \
    { \
        pRet->autorelease(); \
        return pRet; \
    } \
    else \
    { \
        delete pRet; \
        pRet = NULL; \
        return NULL; \
    } \
}

the code

CREATE_FUNC(MessageBoxes(std::string content));

actually is

new(std::nothrow) MessageBoxes(std::string content)();

which has compile error in c++.

but you can write the create funtion similar to CREATE_FUNC by yourself, like

static MessageBoxes* create(std::string content) {
    MessageBoxes* ret = new(std::nothrow) MessageBoxes();
    if(ret && ret->init(content)) { //<----Or anything you wanna init with
        ret->autorelease();
        return ret;
    } else {
        delete ret;
        ret = nullptr;
        return nullptr;
    }
}
