Thread: Using Keyevent

    Default Using Keyevent

    String mess = "Hello".
    I want to use JOptionPane.ShowInputDialog and if the user presses backspace, the code is supposed to remove the last letter of 'mess'.
    But I have NO IDEA how to use KeyListener or Keyevent. So could anyone show me a simple code to show me how to use those methods?
    I looked at many other sources, but the codes are only fragments and i am too much of a noob to figure out the rest.

    Default Re: Using Keyevent

    There are some examples here:
    How to Write a Key Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
    Start with a simple program that catches key events and work with it to see how it key events work.
    If you don't understand my answer, don't ignore it, ask a question.
