Flex 父窗口 子窗口 数据传接

Flex 父窗口 子窗口 数据传递

这里通过一个实例演示Flex父窗口和弹出的子窗口之间的数据传输。

先创建一个MXML component 命名为ListTitleWindow.mxml (Based on : TitleWindow)

xml 代码
1. xml?version="1.0"?encoding="utf-8"?>??<mx:Application?xmlns:mx="http://www.adobe.com/2006/mxml"?layout="absolute"??
2. ????initialize="initApp()">??????<mx:Style?source="styles/main.css"/>??
3. ???????????????? ??????<mx:Script>??
4. ???????? import mx.controls.Alert;
5. ???? import flash.display.StageDisplayState;???? import components.window.ListTitleWindow;
6. ???? import mx.containers.TitleWindow;???? import mx.managers.PopUpManager;
7. ???? import mx.collections.ArrayCollection;
8. ???? private function initApp() : void {
9. ???? }
10. ???? private function showTitleWindow():void {???????? var titleWindowInstance:ListTitleWindow =
11. ???????????? ListTitleWindow(PopUpManager.createPopUp(this, ListTitleWindow, false));????????
12. ???????? titleWindowInstance.title = "Welcome";???????? titleWindowInstance.width = 400;
13. ???????? titleWindowInstance.height = 300;??????????? titleWindowInstance.mainApp = this;??
14. ???????? titleWindowInstance.headTitle = "Select a item.";???????? titleWindowInstance.url="http://localhost:8080/test.xml";
15. ???????? titleWindowInstance.callbackFunction = this.myFunction;????????
16. ???????? PopUpManager.centerPopUp(titleWindowInstance);????? }
17. ????????????? public function myFunction(bb:String):void {
18. ???????? Alert.show(bb);???? }???? ]]>??
19. ??????mx:Script>??
20. ???? ??????<mx:Button?x="63"?y="96"?label="Button"?click="showTitleWindow();"/>??
21. ???? ??mx:Application>??
