I am using actionPreformed(ActionEvent e) to trap when the Enter button is pressed from a JTextField. I would also like to catch the pressing of the tab button. Is there a FocusEvent ?

Hi Nigel,
Yes there is. The caveat is that you find out about it after the window system has completed the function:
FocusListener -->
FocusGained
FocusLost
Keep this in mind, and you will have no problems.
Regards,
Manfred.

Thanks for your reply Manfred. I was being lazy and didn't look up the FocusListener in the Docs. However, I am finding that my validation code is becoming massive is there a good design pattern for GUI validation?
