Hello,
I have a TextField which I'd like to limit to accepting only digits.
I've added a listener to the TextField and can grab each keystroke as it
is entered.
However, I'm unclear as to how I could decide whether or not to let this
keystroke through.
The TextField is not being updated until after I receive the keystroke,
so I suspect there's something I can do to say "not this keystroke."
Any hints and pointers greatly appreciated.
Thanks
--Ray
