1、CCMenu：菜单类，继承自CCLayerRGBA
class CC_DLL CCMenu : public CCLayerRGBA{bool m_bEnabled;//标记菜单是否接收事件public:CCMenu() : m_pSelectedItem(NULL) {}virtual ~CCMenu(){}static CCMenu* create();//几个创建菜单的函数static CCMenu* create(CCMenuItem* item, …);static CCMenu* createWithArray(CCArray* pArrayOfItems);static CCMenu* createWithItem(CCMenuItem* item);static CCMenu* createWithItems(CCMenuItem *firstItem, va_list args);bool init();//初始化相关函数bool initWithArray(CCArray* pArrayOfItems);void alignItemsVerticallyWithPadding(float padding);//下面是和菜单对齐相关的一组函数void alignItemsHorizontally();void alignItemsHorizontallyWithPadding(float padding);void alignItemsInColumns(unsigned int columns, …);void alignItemsInColumns(unsigned int columns, va_list args);void alignItemsInColumnsWithArray(CCArray* rows);void alignItemsInRows(unsigned int rows, …);void alignItemsInRows(unsigned int rows, va_list args);void alignItemsInRowsWithArray(CCArray* columns);void setHandlerPriority(int newPriority);//设置处理的优先级virtual void addChild(CCNode * child);//孩子节点处理相关函数virtual void addChild(CCNode * child, int zOrder);virtual void addChild(CCNode * child, int zOrder, int tag);virtual void registerWithTouchDispatcher();virtual void removeChild(CCNode* child, bool cleanup);virtual bool ccTouchBegan(CCTouch* touch, CCEvent* event);//触摸处理相关函数virtual void ccTouchEnded(CCTouch* touch, CCEvent* event);virtual void ccTouchCancelled(CCTouch *touch, CCEvent* event);virtual void ccTouchMoved(CCTouch* touch, CCEvent* event);virtual void onExit();//退出virtual void setOpacityModifyRGB(bool bValue) {CC_UNUSED_PARAM(bValue);}virtual bool isOpacityModifyRGB(void) { return false;}virtual bool isEnabled() { return m_bEnabled; }//判断和设置是否混合virtual void setEnabled(bool value) { m_bEnabled = value; };protected:CCMenuItem* itemForTouch(CCTouch * touch);tCCMenuState m_eState;CCMenuItem *m_pSelectedItem;};2、CCLayerRGBA：继承自CCLayer和CCRGBAProtocol，颜色相关类class CC_DLL CCLayerRGBA : public CCLayer, public CCRGBAProtocol{public:CREATE_FUNC(CCLayerRGBA);CCLayerRGBA();virtual ~CCLayerRGBA();virtual bool init();virtual GLubyte getOpacity();virtual GLubyte getDisplayedOpacity();virtual void setOpacity(GLubyte opacity);virtual void updateDisplayedOpacity(GLubyte parentOpacity);virtual bool isCascadeOpacityEnabled();virtual void setCascadeOpacityEnabled(bool cascadeOpacityEnabled);virtual const ccColor3B& getColor();virtual const ccColor3B& getDisplayedColor();virtual void setColor(const ccColor3B& color);virtual void updateDisplayedColor(const ccColor3B& parentColor);virtual bool isCascadeColorEnabled();virtual void setCascadeColorEnabled(bool cascadeColorEnabled);virtual void setOpacityModifyRGB(bool bValue) {CC_UNUSED_PARAM(bValue);}virtual bool isOpacityModifyRGB() { return false; }protected:GLubyte_displayedOpacity, _realOpacity;ccColor3B_displayedColor, _realColor;bool_cascadeOpacityEnabled, _cascadeColorEnabled;};3、CREATE_FUNC：定义一个创建函数的宏，使编写更简便#define CREATE_FUNC(__TYPE__) \static __TYPE__* create() \{ \__TYPE__ *pRet = new __TYPE__(); \if (pRet && pRet->init()) \{ \pRet->autorelease(); \return pRet; \} \else \{ \delete pRet; \pRet = NULL; \return NULL; \} \}4、CCMenuItem：菜单项，，继承自CCNodeRGBAclass CC_DLL CCMenuItem : public CCNodeRGBA{protected:bool m_bSelected;//是否被选中bool m_bEnabled;public:CCMenuItem(): m_bSelected(false), m_bEnabled(false), m_pListener(NULL), m_pfnSelector(NULL), m_nScriptTapHandler(0){}virtual ~CCMenuItem();static CCMenuItem* create();bool initWithTarget(CCObject *rec, SEL_MenuHandler selector); CCRect rect();virtual void activate();virtual void selected();//选中virtual void unselected();//取消选中virtual void registerScriptTapHandler(int nHandler);//脚本处理例程相关virtual void unregisterScriptTapHandler(void);int getScriptTapHandler() { return m_nScriptTapHandler; };virtual bool isEnabled();//启用和选择相关virtual void setEnabled(bool value);virtual bool isSelected();void setTarget(CCObject *rec, SEL_MenuHandler selector); //设置回调函数protected:CCObject*m_pListener;SEL_MenuHandler m_pfnSelector;intm_nScriptTapHandler;};4、tCCMenuState：菜单状态typedef enum {kCCMenuStateWaiting,kCCMenuStateTrackingTouch} tCCMenuState;
