Flex TileList 控件示例

让我们按照以下步骤通过创建测试应用程序 − 来检查 Flex 应用程序中 TileList 控件的使用情况 −

以下是在 flex 应用程序中嵌入图像的方法。

<fx:Script>
   <![CDATA[
      //images 文件夹应位于 src 文件夹中
      //并且 maven-mini-logo.png 应位于 images 文件夹中。
      [Bindable]
      [Embed(source="images/maven-mini-logo.png")]
      public var image1:Class;
   ]]>
</fx:Script>

以下是修改后的 mxml 文件 src/com.tutorialspoint/HelloWorld.mxml 的内容。

完成所有更改后，让我们像在 Flex - 创建应用程序 一章中一样，以正常模式编译并运行应用程序。如果您的应用程序一切正常，它将产生以下结果:[ 在线试用 ]
