Limiting the number of characters for TextField

[skanumuru]

How to limit the number of characters for the TextField component? I tried to do it with setMaxLength(), but this does not limit to the specified length.

Thanks,

setMaxLength() will limit the amount of characters that is allowed in the field, but it doesn't actively check to see how long the text is as the user is typing. To be able to do that, you'll have to set up a listener on the field that checks how many characters are in there after every keystroke.

there's a smarter way of doing this:
