Hi... i have a little problem...

I have a JTextField in my JDialog, and I need tath teh JTextField only accept Numbers from the keyboard... In the moment when I Press a Key, I need to know if it is a Number or not... if it's not a number, it's can't be displayed in the JTextField...

And the same with letters...
