How can a KeyListener detect key combinations (e.g., ALT + 1 + 1)

Question

How can I let my custom KeyListener listen for combinations of ALT (or CTRL for that matter) + more than one other key?

Answer 1

I think there's a simpler way which I am using. If the KeyEvent is ev then if you investigate:

(int)ev.getKeyChar()

you find that ctrl-a is 1, ctrl-b is 2 and so on. I wanted to use ctrl-s for save. So I just use:

(((int)ev.getKeyChar())==19)

to detect it. No idea why, but it works fine whereas:

ev.isControlDown() && ev.getKeyChar()=='s'

does not.
