按钮属性

    /* 正常状态下的按钮图片 */  
    CCScale9Sprite* btnNormal = CCScale9Sprite::create("button.png");  
  
    /* 点击状态下的按钮图片 */  
    CCScale9Sprite* btnDown = CCScale9Sprite::create("buttonHighlighted.png");  
  
    /* 按钮标题 */  
    CCLabelTTF *title = CCLabelTTF::create("Touch Me!3324234", "Marker Felt", 30);  
  
    /* 按钮的大小会根据标题自动调整 */  
    CCControlButton* controlBtn = CCControlButton::create(title, btnNormal);  
  
    /* 设置按钮按下时的图片 */  
    controlBtn->setBackgroundSpriteForState(btnDown, CCControlStateSelected);  
    controlBtn->setPosition(ccp(200, 200));  
    this->addChild(controlBtn);  

/* 强制设置按钮大小,如果按钮标题大小超过这个范围，则会自动扩大 */  
    controlBtn->setPreferredSize(CCSize(300, 50));  

按钮事件

/* 当鼠标处于按下并曾经点中按钮时，则触发一次 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDownAction), CCControlEventTouchDown);  
  
    /* 当鼠标处于按下并曾经点中按钮的状态下，鼠标进入按钮范围，则触发一次 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragEnter), CCControlEventTouchDragEnter);  
  
    /* 当鼠标处于按下并曾经点中按钮的状态下，鼠标离开按钮范围，则触发一次 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragExit), CCControlEventTouchDragExit);  
  
    /* 当鼠标处于按下并曾经点中按钮的状态下，鼠标进入按钮范围，则触发，只要达到条件，就不断触发 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragInside), CCControlEventTouchDragInside);  
  
    /* 当鼠标处于按下并曾经点中按钮的状态下，鼠标离开按钮范围，则触发，只要达到条件，就不断触发 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchDragOutside), CCControlEventTouchDragOutside);  
  
    /* 当鼠标处于按下并曾经点中按钮的状态下，鼠标松开且在按钮范围内，则触发一次 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchUpInside), CCControlEventTouchUpInside);  
  
    /* 当鼠标处于按下并曾经点中按钮的状态下，鼠标松开且在按钮范围外，则触发一次 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchUpOutside), CCControlEventTouchUpOutside);  
  
    /* 暂时没有发现能用鼠标触发这个事件的操作，看了注释，应该是由其它事件中断按钮事件而触发的 */  
    controlBtn->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::touchCancel), CCControlEventTouchCancel);  

回调函数

void touchDownAction(CCObject* pSender, CCControlEvent event);  
   void touchDragEnter(CCObject* pSender, CCControlEvent event);  
   void touchDragExit(CCObject* pSender, CCControlEvent event);  
   void touchDragInside(CCObject* pSender, CCControlEvent event);  
   void touchDragOutside(CCObject* pSender, CCControlEvent event);  
   void touchUpInside(CCObject* pSender, CCControlEvent event);  
   void touchUpOutside(CCObject* pSender, CCControlEvent event);  
   void touchCancel(CCObject* pSender, CCControlEvent event); 

CCControlEvent 不是指针，千万不要习惯了就给它加一个*号
