Flex - TileList 控制元件

簡介

TileList 控制元件以平鋪方式顯示多個專案。

類宣告

以下是mx.controls.TileList類的宣告：

public class TileList 
   extends TileBase

Flex TileList 控制元件示例

讓我們按照以下步驟，透過建立一個測試應用程式來檢查在 Flex 應用程式中使用 TileList 控制元件的方法：

以下是將影像嵌入 Flex 應用程式的方法。

<fx:Script>
   <![CDATA[
      //images folder should be in src folder 
      //and maven-mini-logo.png should reside inside images folder.
      [Bindable]
      [Embed(source="images/maven-mini-logo.png")]
      public var image1:Class;
   ]]>
</fx:Script>

以下是修改後的 mxml 檔案src/com.tutorialspoint/HelloWorld.mxml的內容。

完成所有更改後，讓我們像在Flex - 建立應用程式章節中所做的那樣，在普通模式下編譯並執行應用程式。如果您的應用程式一切正常，它將產生以下結果：[ 線上試用 ]
