cocos2dx CCControlButton 按钮事件

bool HelloWorld::init()

。cpp要声明的

 

 

#include "cocos2d.h"
#include "cocos-ext.h"

using namespace cocos2d;
using namespace extension;

class HelloWorld : public cocos2d::CCLayer
{
public:
    // Method 'init' in cocos2d-x returns bool, instead of 'id' in cocos2d-iphone (an object pointer)
    virtual bool init();

    // there's no 'id' in cpp, so we recommend to return the class instance pointer
    static cocos2d::CCScene* scene();
    
    // a selector callback
    void menuCloseCallback(CCObject* pSender);

    // preprocessor macro for "static create()" constructor ( node() deprecated )
    CREATE_FUNC(HelloWorld);
    
//    按下按钮事件回调
    void touchDownAction(CCObject * sender , CCControlEvent * controlEvent);
//    按钮在其内部拾起事件回调
    void touchUpInsideAction(CCObject * sender , CCControlEvent * controlEvent);
//    按钮在其外部拾起事件回调
        void touchUpOutsideAction(CCObject * sender , CCControlEvent * controlEvent);
};
