    Default Regular expressions

    Regular expressions


    You can use a regular expression on a TextField using setRegex.

    Well. Many ways:

    1 - You can listen for entered keys, and if < is entered, you remove it, or display some message...
    2 - you can add a validator via setValidator (but that will only be checked when leaving the field, not when typing)
    3 - As suggested, you can set a regex expression via setRegex(but that will also be only checked when leaving the field, not when typing)

    Default Handle event

    Handle event


    Add a listener to the field using addListener(...) and implement the handleEvent method to do what you want.
    Specify what event you want to listen for, I suppose you need something like Events.KeyPress or one of the other Key... - events.

    Default Texttield.maskRe

    Texttield.maskRe


    I fixed it by using Textfield.maskRe = /your regular expression/
    This will avoid user to type anything which does not comprehend your regex.
    remember on put your regEx into forward slashes!!

    hope this help you guys.
