CCControlSlider 滑动条

void HelloWorld::myInit10()

{

    CCSize size = CCDirector::sharedDirector()->getWinSize();

    //CCControlSlider::create(const char* bgFile, const char* progressFile, const char* thumbFile)

    //滑动条 三个參数非别为：bgFile 滑动条背景图, progressFile 覆盖背景图的那张图, thumbFile 滑块图

    CCControlSlider* slider = CCControlSlider::create("sliderTrack.png", "sliderProgress.png", "sliderThumb.png");

    slider->setPosition(ccp(size.width*0.5, size.height*0.5));

    this->addChild(slider);

    //最小值

    slider->setMinimumValue(0);

    //最大值

    slider->setMaximumValue(100);

    //设定当前值

    slider->setValue(50);

    //回调函数

    slider->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::sliderAction), CCControlEventValueChanged);

    //用来展示当前滑动条的滑动值

    CCLabelTTF *ttf=CCLabelTTF::create("", "Helvetica", 20);

    ttf->setPosition(ccp(200, 210));

    ttf->setString(CCString::createWithFormat("滑动条当前值=%.02f",slider->getValue())->getCString());

    addChild(ttf,0,999);

}

void HelloWorld::sliderAction(CCObject* pSender, CCControlEvent controlEvent)

{

    CCControlSlider* pSliderCtl = (CCControlSlider*)pSender;

    CCLabelTTF *ttf=(CCLabelTTF *)this->getChildByTag(999);

    ttf->setString(CCString::createWithFormat("滑动条当前值=%.02f",pSliderCtl->getValue())->getCString());

}
