AS3不能设置复选框标签 - 需要知道什么时候是装 [英] as3 can't set checkbox label - need to know when it is loaded

问题描述

我们有一个FLA，和高级ActionScript设置下，我们有

We have a fla, and under "Advanced Actionscript Settings", we have

自动声明舞台实例

选中。

然后我们有一大堆的这些声明在我们的文档类的类层次：

We then have a bunch of these declarations at the class level of our document class:

public var spouseCheck:CheckBox;  

如果我将在我的构造spouseCheck.label =嗒嗒，这是行不通的。不过，如果我以后设置它，（当另一事件发生），它的工作。这意味着该复选框被当时完全加载。我怎样才能把一个事件侦听器的复选框，这样我就知道什么时候是完全加载，我可以设置标签？谢谢！

If I set spouseCheck.label = "blah" in my constructor, it does not work. However, if I set it later, (when another event happens), it does work. This implies that the checkbox is completely loaded at that time. How can I put an event listener on the checkbox so that I will know when it is completely loaded, and I can set the label? thanks!

推荐答案

在你设置 spouseCheck.label =嗒嗒类的构造函数，删除该行并加入这一行：

In the constructor of the class where you set spouseCheck.label = "blah", remove that line and add this line:

spouseCheck.addEventListener(Event.ADDED_TO_STAGE,init);

然后创建初始化函数：

Then create the init function:

function init(e:Event):void {
    spouseCheck.label = "blah";
    spouseCheck.removeEventListener(Event.ADDED_TO_STAGE,init);
}

这事件被触发时，spouseCheck是在图像显示（阶段），并应确保它已经准备好。

That event is triggered when spouseCheck is on the displayList (stage) and should ensure it's ready.
