Touch事件处理函数的四种Touch状态:
Widget::TouchEventType::ENDED:
Widget::TouchEventType::CANCELED:
Widget::TouchEventType::MOVED:
Widget::TouchEventType::BEGAN:
button2->setName("normal"); //设置名字
button->setColor(Color3B::GREEN); //设置按钮的颜色
button2->setPosition(button->getPosition() + Vec2(100,0));
//(设置位置参数可以这样使用相加)
btn2->setAnchorPoint(Vec2(0,0.5)); //设置锚点
button->setTitleText("Title Button!"); //设置按钮的标题
button->setTitleColor(Color3B::YELLOW); //标题颜色
button->setFlippedX(true); //设置按钮在X方向上翻转
auto label = button->getTitleRenderer();
//按钮的标题渲染器是一个label
button->runAction(RepeatForever::create(Sequence::create(ScaleTo::create(1.0f, 1.2f),
ScaleTo::create(1.0f, 1.0f),nullptr)));
//按钮一直重复膨胀1.2倍和回复原状的动作
{ //点击删除自己
Layout *layout = Layout::create();

}
button->ignoreContentAdaptWithSize(false);
//继承自Widget,设置参数为true,setContentSize失效,大小等于函数getVirtualRendererSize的返回值
{//设置按钮标题的效果
Label *title = button->getTitleRenderer();
title->enableShadow(Color4B::BLACK,Size(2,-2)); //阴影
title2->enableOutline(Color4B::GREEN, 3);
//It only works on IOS and Android when you use System fonts
}
