Событие джойстика в Java

Question

У меня есть Java-приложение, содержащее одно текстовое поле, и я использую джойстик.

Как я могу что-то сделать в текстовом поле, когда нажата кнопка на джойстике?

Основываясь на учебном проекте здесь: https://theuzo007.wordpress.com/2013/10/26/joystick-in-java-with-jinput-v2/ похоже, что вы должны зацикливаться и просто проверять вещи, поэтому

private void con(){
    JInputJoystick joystick = new JInputJoystick(Controller.Type.STICK);
    while (joystick.isControllerConnected()) {
        // Go trough all components of the controller.
        Component[] components = joystick.getComponents();
        for(int i=0; i < components.length; i++) {
            Component component = components[i];
            Identifier componentIdentifier = component.getIdentifier();

            // Buttons
            if(componentIdentifier.getName().matches("^[0-9]*$")){ // If the component identifier name contains only numbers, then this is a button.
                // Is button pressed?
                if(component.getPollData() != 0.0f) {
                    txt.setText("Button got pressed!")
                }
            }
        }

        // We have to give processor some rest.
        try {
            Thread.sleep(25);
        } catch (InterruptedException ex) {
            Logger.getLogger(JoystickTest.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    txt.setText("Controller not connected");
}
