不依赖于Flex Framework的绑定(flight-framework)

不依赖于Flex Framework的绑定(flight-framework)

项目上界面上与内存里的属性显示一直不一致，而且在做同步的时候，经常会出现不同步的情况下，而且自己定义的事件一直没有时间去彻底的整一下。今天在网上论坛里逛逛，看到一个Binding框架，试用了一下，还是蛮好用的。既然好用，那以后我们的项目就用它吧。方便又高效。
项目地址：http://code.google.com/p/flight-framework/

下面是使用代码实例：
类定义：

package? com.coolexp
package com.coolexp {

import flash.events.EventDispatcher;

import flight.events.PropertyEvent;

public class UserInfo extends EventDispatcher

{

public function UserInfo() { }

private var _age:int; public function get age():int

{

return _age;

?}

?public function set age(value:int):void

?{

var oldValue:Number = _age; _age = value; //you need to dispatch an event to indicate the binding source has changed PropertyEvent.dispatchChange(this,"age",oldValue,_age);

?}

}?}

使用实例：

package{

?import com.coolexp.UserInfo;

?import flash.display.Sprite;

import flash.events.MouseEvent;

import flash.events.TimerEvent;

import flash.text.TextField;

import flash.text.TextFormat;

import flash.utils.Timer;

import flight.binding.Bind;

import flight.binding.Binding;

import flight.events.PropertyEvent;

?public class TestBinding extends Sprite

{

public var txt:TextField;

?private var sourceBinding:Binding;

?public var userInfo:UserInfo;

?public function TestBinding()

?{

?txt = new TextField();

this.addChild(txt);

?userInfo = new UserInfo();

Bind.addBinding(this,"txt.text",this,"userInfo.age");

?var timer:Timer = new Timer(100);

timer.addEventListener(TimerEvent.TIMER,timer_timerHandler);

timer.start();

?}

protected function timer_timerHandler(event:TimerEvent):void

{ // TODO Auto-generated method stub userInfo.

age++;

}

?}

}
