flex4 textArea HTML

Question

关于 Flex4 文本引擎的问题：

我想 1) 将 HTML 文本附加到 textArea text1

我可以加载如下文本：

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);

但我不知道如何添加新文本！

2) 将图片添加到 textArea

所有这些都在新的 TLF 中：有什么想法吗？

问候

Answer 1

这会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"?>

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