Flex：如何为自定义组件创建某种浮动通知消息？
我有一个基于自定义 TextInput 的日期和时间组件，对“在范围内”的内容有一定的限制。但插入范围之外的日期仍然可以。
当用户在 valueCommit 上输入日期时，我希望能够向用户显示悬停通知，以通知/警告他们日期超出了接受的范围。
我正在考虑使用验证器的通知，但我不想使用验证器机制，因为它实际上不是验证，只是通知。类似于工具提示，但仅当用户更改值时才会出现。也许是某种影响？
如果有人有任何想法或者有人做过类似的事情，我洗耳恭听！
I have a custom TextInput-based component for date and time with certain restrictions on what's considered "within range". But it's still fine to insert dates that are outside the range.
When a user types in a date, on valueCommit, I'd like to be able to display a hovering notification to the user, to inform/warn them that the date is outside the accepted range.
I'm thinking of notifications ala the Validators, but I'd rather not use the Validator mechanism because it's really not validation, just notification. Something like a tooltip, but it will only appear if the user changed the value. Maybe an effect of some sort?
If anyone has any ideas or if anyone has done something like this, I'm all ears!

所以我知道你说过你不想使用验证器，但同时，这听起来与你所描述的完全一样。不过，您并没有验证整个表单，只是检查一个字段以确保它符合某些标准。您需要使用 errorString 检查验证器的使用：

So I know you said you don't want to use validators, but at the same time, that sounds exactly like what you're describing. You're not validating the whole form though, just checking a field to make sure it confirms to some standard. You'll want to check out the use of validators with errorString:
