/**
* 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 {@link ActionEvent} is sent.
* Your application can perform some action based on this event by implementing an
* {@link javafx.event.EventHandler} to process the {@link ActionEvent}. Buttons can also respond to
* mouse events by implementing an {@link javafx.event.EventHandler} to process the {@link javafx.scene.input.MouseEvent}
*
*
*
* MnemonicParsing is enabled by default for Button.
*
*
* Example:
*
Button button = new Button("Click Me");
* @since JavaFX 2.0
