Controlbutton按钮的大小可以根据标签内容进行缩放，同时它具有很多按钮所需要的功能。

2. Controlbutton的使用

[HTML] view plain copy print ? <spanstyle="white-space:pre"></span>//正常状态下的按钮图片 Scale9Sprite*btnnormal=Scale9Sprite::create("button.png"); //单击状态下的按钮图片 Scale9Sprite*btnPress=Scale9Sprite::create("buttonHighlighted.png"); //按钮标题 LabelTTF*Title=LabelTTF::create("touchme!","MarkerFelt",30); //创建按钮，按钮的大小根据标题自动调整 Controlbutton*btn=Controlbutton::create(Title,btnnormal); //设置按钮按下时的图片 btn->setBackgroundSpriteForState(btnPress,Control::State::SELECTED); //强制设置按钮大小，如果按钮超过这个范围，则自动扩大 btn->setPreferredSize(Size(300,50)); >setposition(spanstyle="Font-family:Arial,sans-serif;">Point>(200,200)); this->addChild(btn);
btn->setBackgroundSpriteForState(btnPress,Control::State::SELECTED);

State：norMAL、HIGH_liGHTED 、Disabled、SELECTED

norMAL=1<<0,//Thenormal,ordefaultstateofacontrol—thatis,enabledbutneitherselectednorhighlighted. HIGH_liGHTED=11,//Highlightedstateofacontrol.Acontrolentersthisstatewhenatouchdown,draginsIDeordragenterisperformed.YoucanretrIEveandsetthisvaluethroughthehighlightedproperty. Disabled=12,//Disabledstateofacontrol.ThisstateindicatesthatthecontroliscurrentlyDisabled.YoucanretrIEveandsetthisvaluethroughtheenabledproperty. SELECTED=13//Selectedstateofacontrol.Thisstateindicatesthatthecontroliscurrentlyselected.YoucanretrIEveandsetthisvaluethroughtheselectedproperty. 个人暂时不太了解这几个状态的用处，日后补充

DRAG_INSIDE 当处于按下并点中按钮的状态下，进入按钮范围，则触发，可以多次触发
DRAG_OUTSIDE 当处于按下并点中按钮的状态下，离开按钮范围，则触发，可以多次触发
DRAG_ENTER 当处于按下并点中按钮的状态下，进入按钮范围，则触发，一次
DRAG_EXIT 当处于按下并点中按钮的状态下，离开按钮范围，则触发，一次
touch_UP_INSIDE 当处于按下并点中按钮的状态下，鼠标松开且在按钮范围内，则触发，一次
touch_UP_OUTSIDE 当处于按下并点中按钮的状态下，鼠标松开且在按钮范围外，则触发，一次
touch_CANCEL 系统事件中断按钮事件而触发

VALUE_CHANGED 触摸拖曳或 *** 纵控制，让它发出一系列的不同的值。
