我有一个Spark列表包括填写表单应用程序列表的数据提供者。什么是添加一个按钮，每个列表项（窗体应用程序）的最佳方法是什么？此按钮将被命名为开放式，并定位到指定的表单应用程序。

I have a Spark List with a data provider consisting of a list of filled out form applications. What is the best way to add a button to each List Item (form application)? This button will be named Open and will navigate to the specified form application.

在此先感谢您的任何建议！

Thanks in advance for any advice!

推荐答案

这是类似于@ www.Flextras.com说，所以我不打算重复。不过，我将添加一个例子，一两件事情。

This is similar to what @www.Flextras.com said, so I'm not going to repeat that. However, I'll add an example and one or two things.

您定义ItemRenderer可能是这样的：

Your custom ItemRenderer might look like this:

<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
                xmlns:s="library://ns.adobe.com/flex/spark">

    <fx:Script>
        <![CDATA[
            import mx.events.ItemClickEvent;

            private function requestForm():void {
                var event:ItemClickEvent = new ItemClickEvent(ItemClickEvent.ITEM_CLICK);
                event.index = itemIndex;
                event.item = data;
                owner.dispatchEvent(event);
            }
        ]]>
    </fx:Script>

    <s:Label id="labelDisplay" verticalCenter="0" />
    <s:Button right="0" label="open" verticalCenter="0" click="requestForm()" />

</s:ItemRenderer>

两件事情，从Flextras的回答有所不同：

Two things that differ from Flextras' answer:

我用的是内置的，而不是一个自定义事件ItemClickEvent>少 编码 在我派遣的所有者事件的itemRenderer，哪个 实际上包含此的ItemRenderer列表。因为这个， 你不需要泡沫事件。 I use the built-in ItemClickEvent instead of a custom event > less coding I dispatch the event on the owner of the ItemRenderer, which is in fact the List that contains this ItemRenderer. Because of this, you don't need to bubble the Event.

现在，打开按钮被点击时的形式，做这样的事情：

Now to open the form when the Button is clicked, do something like this:

myList.addEventListener(ItemClickEvent.ITEM_CLICK, openForm);

private function openForm(event:ItemClickEvent):void {
    trace("open " + event.item.toString());
}
