flex chat/telnet application send/receive same window in TextArea

Just wanting to know if anybody has seen an example of a telnet/chat or other console like FLEX application where you can use the same TextArea as input/ouput area.

I've been trying to modify the app at:

http://livedocs.adobe.com/flex/3/html/17_Networking_and_communications_8.html

but so far, computer 开发者_StackOverflow中文版says no.

All the implementations I've seen use a combination of TextInput and TextArea.

The challenge is that we'll be using this app to telnet into some old routers and we'll need to do a fair amount of copy/pasting. Based on what I've seen, it seems that I would need to point the mouse into the TextInput in order to be able to right click and paste, which is not very sleak.....

Your thoughts, Fran

edit Just realized that I had trimmed out what was directly pertaining to the question: I was unable to find anything that used the TextArea for input and output; see the below suggestions if custom-component suggestions are ok.

The TextArea component only fires a change event whenever a user adds input. Whenever you set the text field programmatically, a change event does not fire--you could maybe use that as a way to know what is user input and console "responses" by looking for carriage-returns (\r).

I'm unsure if you have a requirement to maintain the user's input at the bottom-most line (like a console), even after the console responds with something like auto-complete. If that's the case, then something a bit more complex would have to come into play (such as remembering where the user's input started/ended) or the requirement of a single-component console needs to be reconsidered--sleek is nice, but not always necessary.
