Flex TileListコントロールの例

テストアプリケーションを作成して、FlexアプリケーションでTileListコントロールの使用を確認するには、次の手順に従います-

Step	Description
1	Create a project with a name HelloWorld under a package com.finddevguides.client as explained in the Flex - Create Application chapter.
2	Add a folder images to src folder. And add sample images to it.
3	Modify HelloWorld.mxml as explained below. Keep rest of the files unchanged.
4	Compile and run the application to make sure business logic is working as per the requirements.

以下は、flexアプリケーションに画像を埋め込む方法です。

<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;
   ]]>
