Hi All!
Just a couple of questions. How do I code the keyboard accelerator Ctrl+Alt? I've found lots of stuff on how to code if you're using only one or the other but not both at the same time.

The other question I have has to do with null strings. I've got a "clear" button set up and the actionlistener coded, but what code do I use to make it clear all textfields when clicked?

All suggestions appreciated!

Lynn

Hi Lynn,

I have a suggestion for your second question of clearing all text fields. As I am giving this suggestion without being aware of the current design of your system, please feel free to comment on it if you feel so.
I suggest you to keep a Collection may be ArrayList or any other, to store the objects of all textfields. On click of "clear" button, iterate this collection and clear the data from all objects. Then call the repaint() of your container to see the effect of the change you made.

Bye
