我怎么能够接触一个有约束力的灵活物体的暗中事件发送者?
原标题:How can I access the implicit event dispatcher of a bindable Flex object?

如果我提出这样的反对:

class Foo {
    [Bindable] public var property: String;
}

的类别中有一个隐性活动发送人处理财产变更事件。 我如何在不提出<条码>的情况下查阅。 Foo <>/code> specified extension EventDispader?

最佳回答

如果将<代码>-keep参数添加到您的汇编线上,你将能够看到它产生的结果。 但是,要迅速解释一下,你就能够像现在这样处理。

因此,在你的主要档案中,你可以重申:

function callFirst(event:FlexEvent):void
{
   foo.addEventListener(PropertyChangeEvent.PROPERTY_CHANGE,test);
   foo.property =  something ;
}

function test(E:Event):void
{
   trace (ObjectUtil.toString(E));
}

印刷:

(mx.events::PropertyChangeEvent)#0
  bubbles = false
  cancelable = false
  currentTarget = (Foo)#1
    property = "something"
  eventPhase = 2
  kind = "update"
  newValue = "something"
  oldValue = (null)
  property = "property"
  source = (Foo)#1
  target = (Foo)#1
  type = "propertyChange"
