awt event, how to make all button listen to 3 keys

[John_Woo]

Hi,

The JButton by default is associated with the key "space bar", pressing
that key same as clicking mouse on it.

I have a swing app which has muli-panels and buttons. I'm wondering how
to make the two "Enter" keys triger button's action as well.

The association with the "space bar" should only apply when a button has
focus. Pressing the space bar when some other component holds focus
won't invoke your button.

I believe your second item can be resolved by setting a button as
default. Every JFrame, JDialog, etc., has a JRootPane. You can then
call that item's getRootPane() method to retrieve it, and then call its
setDefaultButton(JButton) method. That causes the button to take on a
special appearance, and to respond automatically to pressing
Enter/Return while the dialog has focus.
