Fire a JButton with spacebar, or enter key, or mouse click

Question

I\'m trying to get a simple JFrame with a single button to fire an event when any of these events happen:

• The Enter key is pressed AND the JButton has focus

Answer 1

What you can (and probably should) do is create an AbstractAction. You can use the AbstractAction both for your ActionMap as well as for clicking (do JButton.setAction(...))
