Question

我正在使用Flex 4进行开发，并且皮肤中的工具提示存在问题。

我想在皮肤（或其他组件）中定义textinput的工具提示行为。

我创建了一个新皮肤并尝试添加工具提示attriute 直接<s:sparkskin>和<s:RichEditableText>

但工具提示没有显示。

第一：是否可以在皮肤中定义工具提示？如果没有，为什么？
第二：如果有可能，为什么不行呢

感谢您的帮助

启用Textinput时工具提示有效，但禁用

时无效

Answer 1

<s:TextInput tooltip="WEEE!" />

我不知道问题是什么......

编辑：在你的皮肤：

<s:TextInput id="input" toolTip="{input.text}" />

在sparkskin中使用工具提示
