flex一个小模块内切换视图用如下代码:
<?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" minWidth="955" minHeight="600">
<fx:Declarations>
<!-- 将非可视元素(例如服务、值对象)放在此处 -->
</fx:Declarations>
<mx:Panel title="ViewStack Container Example" height="95%" width="95%"
paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10">
<mx:Text width="100%" color="blue"
text="Use the Button controls to change panels of the ViewStack container."/>
<mx:HBox borderStyle="solid" width="100%"
paddingTop="5" paddingLeft="5" paddingRight="5" paddingBottom="5">
<mx:Button id="searchButton" label="Search Panel"
click="myViewStack.selectedChild=search;"/>
<mx:Button id="cInfoButton" label="Customer Info Panel"
click="myViewStack.selectedChild=custInfo;"/>
<mx:Button id="aInfoButton" label="Account Panel"
click="myViewStack.selectedChild=accountInfo;"/>
</mx:HBox>
<!-- Define the ViewStack and the three child containers and have it
resize up to the size of the container for the buttons. -->
<mx:ViewStack id="myViewStack" borderStyle="solid" width="100%" height="80%">
<mx:Canvas id="search" backgroundColor="#FFFFCC" label="Search" width="100%" height="100%">
<mx:Label text="Search Screen" color="#000000"/>
</mx:Canvas>
<mx:Canvas id="custInfo" backgroundColor="#CCFFFF" label="Customer Info" width="100%" height="100%">
<mx:Label text="Customer Info" color="#000000"/>
</mx:Canvas>
<mx:Canvas id="accountInfo" backgroundColor="#FFCCFF" label="Account Info" width="100%" height="100%">
<mx:Label text="Account Info" color="#000000"/>
</mx:Canvas>
</mx:ViewStack>
</mx:Panel>
</s:Application>
本文介绍了一个使用Flex框架实现的视图切换示例。通过ViewStack组件和按钮控制,可以轻松地在不同的面板(如搜索面板、客户信息面板和账户信息面板)之间进行切换。每个面板都定义在一个Canvas中,并可以通过点击相应的按钮来显示。
