1. ControlButton的介绍

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 ?
  1. <spanstyle="white-space:pre"></span>//正常状态下的按钮图片
  2. Scale9Sprite*btnNormal=Scale9Sprite::create("button.png");
  3. //单击状态下的按钮图片
  4. Scale9Sprite*btnPress=Scale9Sprite::create("buttonHighlighted.png");
  5. //按钮标题
  6. LabelTTF*title=LabelTTF::create("touchme!","MarkerFelt",30);
  7. //创建按钮,按钮的大小根据标题自动调整
  8. ControlButton*btn=ControlButton::create(title,btnNormal);
  9. //设置按钮按下时的图片
  10. btn->setBackgroundSpriteForState(btnPress,Control::State::SELECTED);
  11. //强制设置按钮大小,如果按钮超过这个范围,则自动扩大
  12. btn->setPreferredSize(Size(300,50));
  13. >setPosition(spanstyle="font-family:Arial,sans-serif;">Point>(200,200));
  14. this->addChild(btn);

btn->setBackgroundSpriteForState(btnPress,Control::State::SELECTED);

State:NORMAL、HIGH_LIGHTED 、DISABLED、SELECTED

    NORMAL=1<<0,//Thenormal,ordefaultstateofacontrol—thatis,enabledbutneitherselectednorhighlighted.
  1. HIGH_LIGHTED=11,//Highlightedstateofacontrol.Acontrolentersthisstatewhenatouchdown,draginsideordragenterisperformed.Youcanretrieveandsetthisvaluethroughthehighlightedproperty.
  2. DISABLED=12,//Disabledstateofacontrol.Thisstateindicatesthatthecontroliscurrentlydisabled.Youcanretrieveandsetthisvaluethroughtheenabledproperty.
  3. 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

TOUCH_DOWN 按下按钮调用事件
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 触摸拖曳或操纵控制,让它发出一系列的不同的值。
