Itemrenderer 调度自定义事件
我正在尝试从自定义 ItemRenderer 分派自定义事件
这是我的自定义事件
package events
{
import customClass.Product;
import flash.events.Event;
public class CopyProductEvent extends Event
{
public static const COPY_PRODUCT:String = "COPY_PRODUCT";
public var picked:Prodotti;
public function CopyProductEvent(type:String, picked:Product)
{
super(type);
this.picked = picked;
}
}
}
在 itemRenderer 中我有一个函数可以做到这一点:
private function sendEvent(o:Product):void
{
dispatchEvent(new CopyProductEvent(CopyProductEvent.COPY_PRODUCT,o));
}
在主应用程序中我有一个 spark 列表,我尝试向应用程序和列表本身添加一个 EventListener,但它们从未被调用...
this.addEventListener(CopyProductEvent.COPY_PRODUCT,
function(e:Product):void{
...
});
list.addEventListener(CopyProductEvent.COPY_PRODUCT,
function(e:Product):void{
...
});
为什么?!?我哪里做错了?
函数中的事件已正确分派...我无法拦截它..
I'm trying to dispatch a custom event from a custom ItemRenderer
This is my custom event
package events
{
import customClass.Product;
import flash.events.Event;
public class CopyProductEvent extends Event
{
public static const COPY_PRODUCT:String = "COPY_PRODUCT";
public var picked:Prodotti;
public function CopyProductEvent(type:String, picked:Product)
{
super(type);
this.picked = picked;
}
}
}
In the itemRenderer I have a function that does that:
private function sendEvent(o:Product):void
{
dispatchEvent(new CopyProductEvent(CopyProductEvent.COPY_PRODUCT,o));
}
And in the main application I have a spark List and I tried to add an EventListener both to the application and the list itself, but they never be called...
this.addEventListener(CopyProductEvent.COPY_PRODUCT,
function(e:Product):void{
...
});
list.addEventListener(CopyProductEvent.COPY_PRODUCT,
function(e:Product):void{
...
});
Why?!? Where am I doing wrong?
The event from the function is dispatched correctly... I can't intercept it..

听起来您的活动没有冒泡。
在自定义事件构造函数中添加
bubbles
参数(默认情况下为false
):可以在此处找到有关 AS3 中事件冒泡的详细解释:
AS3 中的事件冒泡
Sounds like your event isn't bubbling.
Add the
bubbles
argument (which by default, isfalse
) in your Custom event constructor:A nice explanation on Event bubbling in AS3 can be found here:
