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.

Example:

Button button = new Button("Click Me");
