slider+labelAtlas的使用

2.0之后的增加的滑动进度条改变数值的功能

 

1.使用

// the slider 数量条
CCControlSlider* farmSlider = CCControlSlider::create("cityBuilding/cityBuildingInfo/sliderTrack.png", "cityBuilding/cityBuildingInfo/sliderProgress.png", "cityBuilding/cityBuildingInfo/sliderThumb.png");
farmSlider->setPosition(_B_FARMSLIDER_POS);
farmSlider->setMinimumValue(0.0f);		// slider的最小值
farmSlider->setMaximumValue(256.0f);	// slider的最大值
farmSlider->setValue(0.0f);			// slider的当前值
farmSlider->addTargetWithActionForControlEvents(this, cccontrol_selector(BuildingInfoNext1Layer::farmValueChanged), CCControlEventValueChanged);
this->addChild(farmSlider);

// labelAtlas 变化的数字
CCLabelAtlas* farmLabelAtlas = CCLabelAtlas::create("0", "cityBuilding/cityBuildingInfo/tuffy_bold_italic-charmap.plist");
farmLabelAtlas->setPosition(_B_FARMLABELATLAS_POS);
farmLabelAtlas->setScale(0.3);
this->addChild(farmLabelAtlas,10,210);

2.回调函数

void BuildingInfoNext1Layer::farmValueChanged(CCObject* pSender, CCControlEvent controlEvent)
{
	CCControlSlider* SliderCtl = (CCControlSlider*)pSender;

	int scale;  
	scale = SliderCtl->getValue();

	//slider的当前值   
	//CCLog("CCControlSlider value = %i",scale);

	// 更新labelAtlas
	CCLabelAtlas* label = (CCLabelAtlas*)this->getChildByTag(210);
	label->setString(CCString::createWithFormat("%d", scale)->getCString());
}
