Flex BorderContainer示例

讓我們按照以下步驟通過(guò)創(chuàng)建測(cè)試應(yīng)用程序來(lái)檢查Flex應(yīng)用程序中BorderContainer的使用:

以下是修改后的mxml文件 src / com.tutorialspoint / HelloWorld.mxml 的內(nèi)容。

準(zhǔn)備好所有更改后，讓我們以正常模式編譯和運(yùn)行應(yīng)用程序，就像在 Flex - 創(chuàng)建應(yīng)用程序中一樣 章節(jié)。 如果一切順利，您的應(yīng)用程序，這將產(chǎn)生以下結(jié)果:[在線試用]
