There are a number of options, depending on what you want to do.

If you want to use the TextInput field to display text but NOT to allow the user to edit the text, set the enabled property to false:
<s:TextInput width="175" enabled="false" text="Sample text..." />

Alternatively, if you want to prevent the user from selecting and copying the text set the selectable property to false:
<s:TextInput width="175" selectable="false" text="Sample text..." />

Finally, if you want to prevent pasting into the area, then we have to trap for the Text event. Basically you're looking to see if someone enters more than 1 letter at a time. If so, don't allow it. The reason this works is that when you're typing, each letter fires the event, but if you're pasting, the entire paste operation triggers the event and that would have more than one letter. Of course, if the person wants to paste one letter at a time, this solution will not prevent that...

private function onTextInput(event:flash.events.TextEvent):void
{
  if (event.text.length > 1)
    event.preventDefault();
}

myTextInputField.addEventListener(TextEvent.TEXT_INPUT, onTextInput);

Hope this helps!

So you just want to write but not cut copy and paste?

I have not tried it but why do you try this one:

On de-focus of te component disable the text field.
try overriding the key press events for cut copy and paste for the text filed (not sure if you can override, which also check this out)
