Is it possible to limit characters in native.newTextField

I wanted to know if anyone has found a method to limit the number of characters using the native.newTextField

Perhaps for a high score where only a certain number of characters can be displayed.

native.newTextField( 20, 60, 280, 30, fieldHandler ) [import]uid: 7845 topic_id: 5050 reply_id: 305050[/import]

to limit the number of characters to 10, in the “began” phase of the text field handler add an enterFrame listener that contains

input.text=string.sub(input.text,1,10)

in the “submitted” phase, remove the listener

there’s an “userInput” event.name, but i haven’t seen an example with that
