How to detect user key presses such as conrtrol-P, control-S, and control-M

[Nate Lockwood]

I have a GUI (JFrame) with 3 panels. I'd like the user to be able to type control-key pairs such as: control-P to start a print job and control-S to save but don't see how to do this with KeyListener.

		frame.addKeyListener(new KeyAdapter() {
			@Override
			public void keyPressed(KeyEvent arg0) {
				if (arg0.isControlDown()) {
					switch (arg0.getKeyChar()) {
					case 'P':
					case 'p':
						PrintAs();
						break;
					case 'S':
					case 's':
						SaveAs();
						break;
					}

				}
			}
		});

If the "if" statement is removed or I change the if statement to if (!arg0.isControlDown()) { the switch works whether the control key is pressed or not. Otherwise nothing happens. I'm on OS-X right now and need this to work with LINUX as well (and probably MS XP at some point).

KeyBindings is what you want.
