访问＆QUOT; currentState的＆QUOT;从其他类？ [英] Access "currentState" from other classes?

问题描述

我做在我initApp.as我已经创建了另一个类，需要编辑在currentState，这是主要的。至于（initApp.as）仅在访问ActionScript 3的一个小应用程序。我发现了一个解决方案，这样我可以从我的其他类达到currentState属性：Application.application.currentState

I'm making a little application in Actionscript 3. In my initApp.as I have created another class which needs to edit the currentState, which is only accessible from the main .as (initApp.as). I found a solution such that I can reach the currentState property from my other class: Application.application.currentState.

但是，这是不是一个很好的解决方案，因为它夫妻的类太多了..有从其他类编辑在currentState更好的办法？

This is however not a good solution as it couples the classes too much.. is there a better way of editing the currentState from other classes?

推荐答案

我会建议你使用事件和中央调度。例如：

I would suggest you use events and a central dispatcher. For example:

在InitApp.as

In InitApp.as

Dispatcher.instance.addEventListener(StateChangeEvent.STATE_CHANGE, onStateChange);

protected function onStateChange(e:StateChangeEvent):void
{
    this.currentState = e.newState;
    // perhaps dispatch another state change event that all views can listen for?
}

在你的其他类

Dispatcher.instance.dispatchEvent(new StateChangeEvent(StateChangeEvent.STATE_CHANGE, newState);

，其中Dispatcher是一个独立的，并StateChangeEvent是一个newState属性自定义事件。祝你好运！

where Dispatcher is a singleton and StateChangeEvent is a custom event with a newState property. Good luck!
