public class Wizard2Controller
extends AbstractWizardController
This is a view controller for one of the steps in the wizard. The "back" and "finish" buttons of the action-bar that
is shown on each view of the wizard are defined in the AbstractWizardController class. So this class only needs to
define the "next" button. By using the @LinkAction annotation this button will link on the next step of the
wizard. This annotation was already described in tutorial 2.
When looking at the @FXMLController annotation of the class you can find a new feature. next to the fxml files that
defines the view of the wizard step a "title" is added. This defines the title of the view. Because the wizard is
added to a Stage by using the Flow.startInStage() method the title of the flow is automatically bound to the window
title of the Stage. So whenever the view in the flow changes the title of the application window will change to the
defined title of the view. As you will learn in future tutorial you can easily change the title of a view in code.
In addition to the title other metadata like a icon can be defined for a view or flow.
