问题描述
分段按钮，segmentedControl由一个或多个segment组成，点击不同段得到不同的信息，每次只能选择一段。 CASegmentedControl* defaultCASegmentControl = CASegmentedControl::createWithCenter(CCRect(size.width*0.5, size.height*0.15, size.width*0.8, size.height*0.1), 3);//创建一个3段按钮defaultCASegmentControl->setSelectedAtIndex(1);//默认选中第一段 this->getView()->addSubview(defaultCASegmentControl); CASegmentedControl* segmented = CASegmentedControl::createWithCenter(CCRect(size.width*0.5, size.height*0.3, size.width*0.8, size.height*0.1), 3);for (int i = 0; i setTitleAtIndex(Title,i,CAControlStateAll);//把字体添加进全状态（正常，高亮，选中）按钮中segmented->setTitleFontName("fonts/Marker Felt"); //设置字体类型segmented->setBackgroundImageAtIndex(CAImage::create(segNormal),i,CAControlStateNormal); //设置0,1,2个按钮正常时候的背景图片segmented->setBackgroundViewAtIndex(CAScale9ImageView::createWithImage(CAImage::create(segHighlighted)), i, CAControlStateHighlighted);segmented->setBackgroundImageAtIndex(CAImage::create(segSelect), i, CAControlStateSelected);}segmented->setTitleColorAtIndex(CAColor_white, 0, CAControlStateAll);//设置0号按钮的字体颜色segmented->setTitleColorAtIndex(CAColor_gray, 1, CAControlStateAll);segmented->setTitleColorAtIndex(CAColor_yellow, 2, CAControlStateAll); segmented->addTarget(this,CAControl_selector(FirstViewController::segmentCallback));//添加事件void FirstViewController::segmentCallback(CAControl* btn, CCPoint point){ //CAControl下的子类的事件回调函数必须有这两个类型形参switch (segmented->getSelectedIndex()){case 0: defaultPage->setText(UTF8("默认样式")); break;case 1: defaultPage->setText("The second page"); break;case 2: defaultPage->setText("The third page"); break;default: break;}}
