Bloke on the Flexcoders list needed a TextArea that wasn’t selectable. Editable didn’t work because you could still select text, and it showed the i beam cursor. Enabled didn’t work because it colored the text the wrong way, and forced him to use custom styling (or CSS selectors). TextArea doesn’t have a selectable property, and since it extends Sprite, not TextField, there is no property to hide. It utilizes mx.core.UITextField via composition, and the textField property is protected, so you CAN access it via inheritance. This example here shows how to override the selectable property and end up with a non-selectable TextArea.
Zidane iPod, anyone?
