CCControlButton的使用

原文链接：http://blog.sina.com.cn/s/blog_7d1531ed010167pq.html

CCControlButton 是cocos2d-x新封装的UI 类似oc的UIButton 可以设置各个状态的png支持CCScale9Sprite根据大小拉伸图片!







CCSprite* tmp =
CCSprite::create("CloseNormal.png");

CCSize size =tmp->getContentSize();

CCLog("wh:%f,%f", size.width, size.height);
tmp->release();

CCScale9Sprite* backGround = CCScale9Sprite::create("CloseNormal.png");

CCControlButton*button=CCControlButton::create(backGround);
button->setPosition(200,
200);

button->setPreferredSize(CCSizeMake(size.width, size.height));

this->addChild(button);

button->addTargetWithActionForControlEvents(this,cccontrol_selector(HelloWorld::menu1Callback),
CCControlEventTouchUpInside);

voidHelloWorld::menu1Callback(cocos2d::CCNode *pSender)
{
CCControlButton*button=(CCControlButton*)pSender;
CCLog("%d",button->getTag());//根据tag值判断按钮
CCLOG("menu1Callback");
}

如果button->setPreferredSize(CCSizeMake(size.width*3,size.height*3));就会变成第二张图片走形了

疑惑的是 CCScale9Sprite有什么作用是为了适应button的拉扯 效果还是那么难看！

解决办法：对CCScale9Sprite进行缩放规划才可以

CCSprite* tmp=
CCSprite::create("CloseNormal.png");
CCSize size =tmp->getContentSize();

CCRectfullRect =
CCRectMake(0,0,size.width, size.height);
CCRect insetRect =
CCRectMake(2,2,size.width-4, size.height-4);
CCScale9Sprite* backGround =
CCScale9Sprite::create("CloseNormal.png", fullRect,insetRect);
