如何允许在 Spark Textarea 中使用选项卡？

Question

我想在 Spark TextArea 中输入制表符，我找到的唯一示例是 mx TextArea。

这是我根据建议使用的测试数据manageTabKey：

var config:Configuration = new Configuration();
var parser:ITextImporter;

config.manageTabKey = true;
parser = TextConverter.getImporter(TextConverter.PLAIN_TEXT_FORMAT, config);

textarea.textFlow = parser.importToFlow("test data");

MXML：

<s:TextArea id="textarea" width="100%" height="100%">

</s:TextArea>

这应该会让您得到想要的结果：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" 
               minWidth="955" minHeight="600"
               creationComplete="creationCompleteHandler(event)">
    <fx:Script>
        <![CDATA[
            import mx.events.FlexEvent;

            import flashx.textLayout.elements.Configuration;

            protected function creationCompleteHandler(event:FlexEvent):void {
                (sparkTextArea.textFlow.configuration as Configuration).manageTabKey = true;
            }

        ]]>
    </fx:Script>
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:TextArea id="sparkTextArea" />
</s:Application>

这适用于 Flex 4.6.0
