介绍 (Introduction)

TileList控件显示以tile为单位布置的多个项目。

Class 声明 (Class Declaration)

以下是mx.controls.TileList类的声明 -

public class TileList 
   extends TileBase

公共方法 (Public Methods)

S.No	方法和描述
1	TileList() 构造函数。

方法继承 (Methods Inherited)

该类继承以下类中的方法 -

mx.controls.listClasess.TileBase
mx.controls.listClasess.ListBase
mx.core.ScrollControlBase
mx.core.UIComponent
mx.core.FlexSprite
flash.display.Sprite
flash.display.DisplayObjectContainer
flash.display.InteractiveObject
flash.display.DisplayObject
flash.events.EventDispatcher
Object

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控件的用法 -

步	描述
1	在cn.xnip.client包下创建一个名为HelloWorld的项目，如Flex - Create Application一章中所述。
2	将文件夹images添加到src文件夹。并添加样本图像。
3	修改HelloWorld.mxml ，如下所述。保持其余文件不变。
4	编译并运行应用程序以确保业务逻辑按照要求运行。

以下是在flex应用程序中嵌入图像的方法。

<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>

以下是修改后的mxml文件src/cn.xnip/HelloWorld.mxml 。

<?xml version = "1.0" encoding = "utf-8"?>
<s:Application xmlns:fx = "http://ns.adobe.com/mxml/2009"
   xmlns:s = "library://ns.adobe.com/flex/spark"
   xmlns:mx = "library://ns.adobe.com/flex/mx"
   width = "100%" height = "100%" minWidth = "500" minHeight = "500">
   <fx:Style source = "/com/xnip/client/Style.css" />	
   <fx:Script>
      <![CDATA[
         [Bindable]
         [Embed(source = "images/maven-mini-logo.png")]
         public var image1:Class;
         [Bindable]
         [Embed(source = "images/flex-mini.png")]
         public var image2:Class;
         [Bindable]
         [Embed(source = "images/gwt-mini.png")]
         public var image3:Class;
         [Bindable]
         [Embed(source = "images/junit-mini-logo.png")]
         public var image4:Class;
         [Bindable]
         [Embed(source = "images/cpp-mini-lib-logo.png")]
         public var image5:Class;
      ]]>
   </fx:Script>
   <s:BorderContainer width = "630" height = "480" id = "mainContainer" 
      styleName = "container">
      <s:VGroup width = "100%" height = "100%" gap = "50" 
         horizontalAlign = "center" verticalAlign = "middle">
         <s:Label id = "lblHeader" text = "Complex Controls Demonstration" 
            fontSize = "40" color = "0x777777" styleName = "heading" />
         <s:Panel id = "tileListPanel" title = "Using TileList" 
            width = "500" height = "300">
            <s:layout>
               <s:VerticalLayout  gap = "10" verticalAlign = "middle" 
                  horizontalAlign = "center" />
            </s:layout>					
            <s:Label width = "100%" textAlign = "center" color = "0x323232"
               text = "A TileList control displays items in rows and columns." />
            <mx:TileList id = "tileList" height = "200" width = "350"  
               maxColumns = "2" rowHeight = "100" columnWidth = "150">
               <mx:dataProvider>
                  <fx:Array>
                     <fx:Object label = "Maven" icon = "{image1}" />
                     <fx:Object label = "Flex" icon = "{image2}" />
                     <fx:Object label = "GWT" icon = "{image3}" />
                     <fx:Object label = "JUnit" icon = "{image4}" />
                     <fx:Object label = "C++" icon = "{image5}" />
                  </fx:Array>
               </mx:dataProvider>
            </mx:TileList>					
         </s:Panel>
      </s:VGroup>	 
   </s:BorderContainer>	
</s:Application>

一旦准备好完成所有更改，让我们像在Flex - Create Application章节中那样在正常模式下编译和运行应用程序。
