Default key behavior of JFrame

Hi,

I am using jdk1.5 development kit for development. I am developing
desktop base application. I created a frame (JFrame frm), added two
buttons with label "OK" and "Cancel", some text fields and labels. I
want to know, how I can define default behavior of frame on key
stokes, mean to say, if I pressed ESC key any time then frame should
perform "Cancel" behavior and "OK" behavior on press ENTER any time.
Is it possible without adding listener in all components?

Regards,

I guess you'll have to implement KeyListener for the Frame

see http://mindprod.com/jgloss/jbutton.html

look at the sample code lines:

// set up keystroke shortcut Alt-F2
jButton2.setMnemonic( KeyEvent.VK_F2 );

Not quite what you want. Giving the button focus make Enter often act
like a push, though sometimes you need to hit space.
