cocos2dx CCControlSlider 滑动条

1. //滑动条
   
2. CCControlSlider * slider = CCControlSlider ::create("sliderBg.png","sliderProgress.png","sliderThumb.png");
   
3. slider->setPosition(ccp(200,170));
   
4. // 设置滑动条最大值
   
5. slider->setMaximumValue(100);
   
6. // 设置滑动条最小值
   
7. slider->setMinimumValue(0);
   
8. addChild(slider,921);
   
9. // 设置监听 ， 但滑动条的值发生变化后 ， 会相应 valueChanged 函数
   
10. //CCControlEventValueChanged值改变
    
11. slider->addTargetWithActionForControlEvents(this,cccontrol_selector(HelloWorld::valueChanged),CCControlEventValueChanged);
    
12. // 用于展示当前滑动条的滑动值
    
13. cclabelTTF * label = cclabelTTF ::create();
    
14. label->setColor(ccc3(255,0));
    
15. label->setPosition(ccp(200,200));
    
16. 
    
17. label->setString(CCString::createWithFormat("滑动条当前值＝ %0.02f",slider->getValue())->getCString());
    
18. addChild(label,922);

1. void HelloWorld::valueChanged()
   
2. {
   
3. // 利用tag 来确定
   
4. CCControlSlider *slider = (CCControlSlider * )this->getChildByTag(921);
   
5. cclabelTTF * label =(cclabelTTF * )this->getChildByTag(922);
   
6. label->setString(CCString::createWithFormat("滑动条的当前值 ＝ %.02f",serif; font-size:12px; line-height:1.8em">
   
7. }
