flex4 textArea HTML

Question

问题是关于Flex4文本引擎的：

我想1）将HTML文本附加到textArea text1

我可以像这样加载文本：

var s:String='<p fontSize="12">TextArea with<span fontWeight="bold">TLF</span> block</p>';
text1.textFlow = TextFlowUtil.importFromString(text1.text + s, TextConverter .TEXT_FIELD_HTML_FORMAT);

但是我不知道该如何添加新文字！

2）将图像添加到textArea

新的TLF中的所有这些：有什么想法吗？

问候

Answer 1

这将设置文本并加载图像，然后使用计时器每5秒添加一次文本：

<?xml version="1.0" encoding="utf-8"?>

               xmlns:s="library://ns.adobe.com/flex/spark"

               minWidth="955"
               minHeight="600"
               creationComplete="creationCompleteHandler(event)">

    <fx:Script>

                "This text can be appended to.<br />" +

            private var timer:Timer;

            protected function creationCompleteHandler(event:FlexEvent):void
            {
                // 5-seconds later, append text
                timer = new Timer(5000);
                timer.addEventListener(TimerEvent.TIMER, timerHandler);
                timer.start();
            }

            protected function timerHandler(event:TimerEvent):void
