Flex控制外部加载的swf文件[外部swf文件flex版]
1-首先写一个加载外部swf文件的类
package Package
{
import flash.display.DisplayObject;
import flash.display.Loader;
import flash.events.*;
import flash.net.URLRequest;
import mx.core.UIComponent;
import mx.events.FlexEvent;
public class CtmObjLoader extends UIComponent
{
private var loader:Loader;
private var ProgressHandle:Function=null;
public var _bLoaded:Boolean=false;
public function CtmObjLoader(UrlRequest:String=null,progressHandle:Function=null)
{
super();
if(UrlRequest)LoadThis(UrlRequest,progressHandle);
}
public function LoadThis(UrlRequest:String,progressHandle:Function=null):void{
RemoveChild();
loader = new Loader();
ProgressHandle=progressHandle;
//DeleteListeners(loader.contentLoaderInfo);
configureListeners(loader.contentLoaderInfo);
addChild(loader);
var request:URLRequest = new URLRequest(UrlRequest);
loader.load(request);
}
public function UnLoadThis():void{
try{
RemoveChild();
this.parent.removeChild(this);
}catch(e:Error){}
//this=null;
}
public function get content():DisplayObject{
if(!_bLoaded)return null;
return loader.content;
}
private function RemoveChild():void{

对flex datagrid scrollbar位置设置需要一些特殊处理，见如下截图：
关键点在于DataGrid拥有protected的 horizontalScrollBar 和 verticalScrollBar 属性，对其设置即可实现如上截图的效果。代码如下： package com.util.component

import mx.controls.DataGrid;
import mx.events.DataGridEvent;

在字符串转换为int类型必须使用 最好如下：
var a:int=int(str);
上面转换如果采用如下强制转换则
var a:int =str as int;
得到数据为0 为错误数据。
在项目中两个int相加结果超过一个int的范围时出现错误！
经过自己bug查找到错误原因是因为int数据类型范围太小奥！只好改为Number类型。结果才正确！晕死！
