Question

I want to add a sort of cheat code to a program I am writing. I was wondering how I could do this. For example when I am anywhere on the screen I want to be able to press a certain key combination for example ctl + alt + w, and get some action from that. My guess would be using a keylistener and adding it to the frame. Any help would be appreciated.

Thanks,

class cheat implements KeyListener{

      public void keyPressed(KeyEvent e){

          char key = e.getKeyChar();

          System.out.println(key);

      }
      public void keyReleased(KeyEvent e){}

      public void keyTyped(KeyEvent e){}



      }

Yes you would add a keylistener. Inside your trigger for your listener, you can pass the KeyEvent to a secondary method to encapsulate the logic, then act appropriately.

isCheatCode(KeyEvent e) {
    if(e.getKeyCode() == KeyEvent.VK_W) {
        int mods = e.getModifiers();
        return (mods & InputEvent.ALT_MASK != 0)
        && mods & InputEvent.CTRL_MASK != 0;
    }
    return false;
}
