Java/Swing - Creating Hotkeys

Question

I have a JFrame with multiple components on it, and I am not able to have the keyPressed event from the JFrame called because the frame is never focused, and the event only works when it is focused. How should I make a similar event but only have it work when the window is focused, not just the individual component?

Have a look at [How to Use Key Bindings](http://docs.oracle.com/javase/tutorial/uiswing/misc/keybinding.html) — MadProgrammer, Aug 20 '15 at 03:46
@AndrewThompson It is the answer, but it'd be a link only answer, so :( - but yes, it might be a good close reason as nothing else is going to answer the question — MadProgrammer, Aug 20 '15 at 03:50
I'm voting to close this question as off-topic because the question can best be answered by reading the [How to Use Key Bindings](http://docs.oracle.com/javase/tutorial/uiswing/misc/keybinding.html) tutorial — MadProgrammer, Aug 20 '15 at 03:50

I found a thread on this site that does it extremely easily, no need for key bindings or anything. All this thing is, is an overrided method of dispatchKeyEvent; I don't know if this is the best way of doing it, but it works for me

Here's a link to the thread How can I listen for key presses (within Java Swing) across all components?

KeyboardFocusManager.getCurrentKeyboardFocusManager()
    .addKeyEventDispatcher(new KeyEventDispatcher() {
        @Override
        public boolean dispatchKeyEvent(KeyEvent e) {
            System.out.println("Got key event!");
            return false;
        }
    });

The easiest way would be to place a JPanel in the JFrame, then do everything using that JPanel instead of the JFrame.
