僅在Tabs中使用，對(duì)應(yīng)一個(gè)切換頁(yè)簽的內(nèi)容視圖。

說(shuō)明：
開(kāi)發(fā)前請(qǐng)熟悉鴻蒙開(kāi)發(fā)指導(dǎo)文檔 ：[gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md]
該組件從API Version 7開(kāi)始支持。后續(xù)版本如有新增內(nèi)容，則采用上角標(biāo)單獨(dú)標(biāo)記該內(nèi)容的起始版本。

子組件

支持單個(gè)子組件。

說(shuō)明：

可內(nèi)置系統(tǒng)組件和自定義組件，支持渲染控制類型（[if/else]、[ForEach]和[LazyForEach]）。

接口

TabContent()

屬性

除支持[通用屬性]外，還支持以下屬性：

說(shuō)明：

• TabContent組件不支持設(shè)置通用寬度屬性，其寬度默認(rèn)撐滿Tabs父組件。
• TabContent組件不支持設(shè)置通用高度屬性，其高度由Tabs父組件高度與TabBar組件高度決定。
• vertical屬性為false值，交換上述2個(gè)限制。
• TabContent組件不支持內(nèi)容過(guò)長(zhǎng)時(shí)頁(yè)面的滑動(dòng)，如需頁(yè)面滑動(dòng)，可嵌套List使用。
