cocos2dx CCControlSlider 滑動條

1. //滑動條
   
2.     CCControlSlider * slider = CCControlSlider ::create("sliderBg.png", "sliderProgress.png", "sliderThumb.png");
   
3.     slider->setPosition(ccp(200, 170));
   
4. //    設置滑動條最大值
   
5.     slider->setMaximumValue(100);
   
6.     //    設置滑動條最小值
   
7.     slider->setMinimumValue(0);
   
8.     addChild(slider,0,921);
   
9. //    設置監聽 ， 但滑動條的值發生變化後 ， 會相應 valueChanged 函數
   
10. //CCControlEventValueChanged值改變
    
11.     slider->addTargetWithActionForControlEvents(this, cccontrol_selector(HelloWorld::valueChanged), CCControlEventValueChanged);
    
12. //    用於展示當前滑動條的滑動值
    
13.     CCLabelTTF * label = CCLabelTTF ::create();
    
14.     label->setColor(ccc3(255, 0, 0));
    
15.     label->setPosition(ccp(200, 200));
    
16.     
    
17.     label->setString(CCString::createWithFormat("滑動條當前值＝ %0.02f",slider->getValue())->getCString());
    
18.     addChild(label,0,922);
