Java Swing GUI Hidden Input

Question

I made a simple JFrame with Swing. I want to know how I would go about making a non-visible input that would open up another JFrame I have in another class. (Like cheat codes in video games, you enter a combination and something happens.) I am not sure how to capture the user input without a text field.

Answer 1

You should use keybinding attached to your JFrame. You would want to store keystrokes as a String internally and after each keystroke, see whether the user has entered a recognizable cheat code or just listen for a return keypress as a delimiter for the code.

Keep in mind that if a component within that JFrame has focus and also implements the same key bindings, then that component will take precedence over the JFrame, effectively intercepting the keystrokes.
