I'm trying to validate the entry of text using Python/tkInter

def validate_text():
    return False


text = Entry(textframe, validate="focusout", validatecommand=validate_text)

where validate_text is the function - I've tried always returning False and always returning True and there's no difference in the outcome..? Is there a set of arguments in the function that I need to include?

Edit - changed from NONE to focusout...still not working
