How to create a "Command Line"/"Text Validation"

Question

I want to create a command line like the picture. I'm using "Input Text" method for text. Variable name is "myText", Instance Name is "line".
How can I use "if" in input text like this:
Command name is: exit, if user wrote "exit" command, exit the flash app.

This is a pretty old thread (I know I came across this while searching for something similar recently), but I figured I'd throw this out there in case other people might find this useful. As I write this, JavaFX's latest version is 1.3... which may have added the needed functionality since the last post.
You can now create a multi-line text area using a TextBox and by specifying the nubmer of lines and setting the "multiline" value to true. It may not offer all of the same functionality as JTextArea, but it did the job for what I needed... newlines by pressing enter, scrollbar if text surpasses height, etc.
Here's a simple example:
Group {
   content: [
      TextBox {
         text: "This is a multi-line textbox"
         lines: 10  // <-- this may/may not be necessary depending on your situation. Default is 5.
         multiline: true
