public class Button
extends ButtonBase
A simple button control. The button control can contain text and/or a
graphic. A button control has three different modes
Normal: A normal push button.
Default: A default Button is the button that receives a keyboard
VK_ENTER press, if no other node in the scene consumes it.
Cancel: A Cancel Button is the button that receives a keyboard
VK_ESC press, if no other node in the scene consumes it.
When a button is pressed and released a ActionEvent is sent. Your
application can perform some action based on this event by implementing
an EventHandler to process the ActionEvent. Buttons can also respond to
mouse events by implementing an EventHandler to process the MouseEvent
MnemonicParsing is enabled by default for Button.
Either I'm missing something or you are.
Good luck.
