		<description><![CDATA[在显示搜索结果，标记重点文本内容等很多时候都需要用到文本高亮显示，接下来的例子演示了Flex中如何利用TextRange类，高亮(hightlight)显示文本内容。下面的Demo中用了两个Slider，拖动来选择高亮文本范围。
让我们先来看一下Demo（可以右键View Source或点击这里察看源代码）：









下面是完整代码(或点击这里察看)：

		<description><![CDATA[这个例子实际上和前面的Flex中格式化Slider控件的数据一样，除了实现的方法不一样以外，其效果上的差别只不过这个是带小数而且是多个的tips。这里主要是通过监听thumbPress和thumbRelease两个事件来记录是哪一个slider被滑动了。
另外需要注意的是，如果使用的是Flex Builder 3编译本例，那么有可能会因为类似下面的警告而无法创建发布程序：
Severity Description Resource In Folder Location Creation Time Id 1 Data binding will not be able to detect changes when using square bracket operator.  For Array, please use ArrayCollection.getItemAt() instead. main.mxml main line 65 2008/03/28 1:06:18 98
