Flex4 Alert PopupManager 演示样本

Flex4中间PopupManager分类似模仿桌面用户界面弹出窗体，有些人还喜欢JS弹出屏幕操作，底层接口灰色禁用掉。

创建需要要喷射形式的文件，码如下面：

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009"
  xmlns:s="library://ns.adobe.com/flex/spark"
  xmlns:mx="library://ns.adobe.com/flex/mx"
  layout="vertical" title="弹出窗体"
  width="600" height="400" showCloseButton="true"
  close="PopUpManager.removePopUp(this);">
  <fx:Script>
    <![CDATA[
      import mx.managers.PopUpManager;
    ]]>
  </fx:Script>
  <s:Group width="100%">
    <s:Label text="2014-5-14 09:28:26"/>
  </s:Group>
  <s:TextArea id="textArea"  width="100%" height="100%"/>
</mx:TitleWindow>

測试程序例如以下：

<?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%"
  initialize="init()">
<fx:Script><![CDATA[
  import mx.events.CloseEvent;
  import mx.controls.Alert;
  import mx.managers.PopUpManager;

  private function showAlert(event:MouseEvent):void {
    Alert.show(‘这是一个弹出窗体!‘, ‘弹出窗体測试‘);
  }

  private function showPopUp(event:MouseEvent):void {
	//PopUpManager 相关初始化工作。先创建，调整位置。安排监听事件。
    var titleWindow:TestTitleWindow1 = TestTitleWindow1(
      PopUpManager.createPopUp(this, TestTitleWindow1, true));
    titleWindow.x = 50;
    titleWindow.y = 50;
    titleWindow.addEventListener(CloseEvent.CLOSE, onCloseTTW);
  }
  //弹出窗体关闭时间函数
  private function onCloseTTW(event:CloseEvent):void {
    var ttw:TestTitleWindow1 = TestTitleWindow1(event.target);
	TextArea1.text = ttw.textArea.text;
  }
]]></fx:Script>
  <s:layout>
    <s:VerticalLayout paddingLeft="10" paddingTop="10"
      paddingRight="10" paddingBottom="10"/>
  </s:layout>
  <s:Button label="測试Alert" click="showAlert(event)"/>
  <s:Button label="測试TestTitleWindow" click="showPopUp(event)"/>
  <s:Label text="TestTitleWindow:"
    fontWeight="bold"/>
  <s:TextArea id="TextArea1" width="100%"
    height="100%"/>
</s:Application>
