Flex里Application和TitleWindow数据交互方法
在Flex里,一般的弹出窗口(除了Alert以外)都可以用TitleWindow组件完成,主窗口和TitleWindow的数据传输可以用以下方法:
假设TitleWindow的实例文件为titleWin.mxml,则要在Application中用PopUpManager创建一个titleWin的引用
private var popWin:titleWin = titleWin(PopUpManager.createPopUp(this,titleWin,true));
如果要将Application的一个组件的值传给titleWin,如Application的id="userName"的TextInput的值传给titleWin,必须先在titleWin.mxml里声明一个TextInput的组件:
public var userNameInPop:TextInput;
然后在Application里:
popWin.userNameInPop=userName;
这样就相当于把Application的userName的TextInput组件传给了titleWin,可以在titleWin.mxml里绑定这个值然后在文本框里显示出来:
[Bindable]
public var userNameInPop:TextInput;
<mx:TextInput x="110" y="39" id="popUserName" text="{userNameInPop.text}"/>
<?xml version="1.0" encoding="utf-8"?><mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="400" height="300" showCloseButton="true" close="PopUpManager.removePopUp(this)"> <mx:Script> <![CDATA[ import mx.managers.PopUpManager; //[Bindable] //public var userName:TextInput; [Bindable] public var userNameInPop:TextInput; [Bindable] public var userEmailInPop:TextInput; private function showText():void { userNameInPop.text=popUserName.text; userEmailInPop.text=popEmail.text; PopUpManager.removePopUp(this); } ]]> </mx:Script> <mx:Label text="用户名:" x="57" y="41"/><mx:TextInput x="110" y="39" id="popUserName" text="{userNameInPop.text}"/> <mx:Label text="邮箱:" x="57" y="71"/><mx:TextInput x="110" y="69" id="popEmail" text="{userEmailInPop.text}"/> <mx:Button x="157" y="99" label="Button" click="showText()"/> </mx:TitleWindow>mainWindow.mxml<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ import mx.managers.PopUpManager; private function pop():void { var popWin:titleWin = titleWin(PopUpManager.createPopUp(this,titleWin,true)); popWin.title="弹出窗口"; popWin.userNameInPop=userName; popWin.userEmailInPop=email; } ]]> </mx:Script> <mx:Label text="用户名:" x="106" y="95"/><mx:TextInput x="159" y="91" id="userName" text="ssz413"/> <mx:Label text="邮箱:" x="106" y="144"/><mx:TextInput x="159" y="142" id="email" text="ssz425"/> <mx:Button x="207" y="189" label="Button" click="pop()"/> </mx:Application>?
