Note: Tutorial 4 depends on tutorial 3. To understand the complete tutorial please check tutorial 3 because some
informations are documented there. Here only the features and code that differ from tutorial 3 will be described.
This is the base class for all view controllers in the wizard. Each view has a action-bar with an "back", "next" and
"finish" button. All 3 buttons are defined in this abstract class and will be injected by DataFX.
In contrast to tutorial 3 all buttons are annotated by the @ActionTrigger annotation that was introduces in tutorial 1.
By using this annotation a defined action will be called once the button is pressed. All these actions are defined by
an unique id. In this case there are three different ids: "back", "finish" and "next". The action for these ids is
defined in the
Tutorial4Main class. As you can see in the
Tutorial4Main class some of the action ids
are unique for a view and other are unique in a flow. By doing so you can define global actions for a flow or actions
that will execute a specific tasks in each view.
About the action-bar:
The action-bar is defined in the actionBar.fxml file. When looking at the fxml files of the wizard views
(wizardStart.fxml, wizard1.fxml, ...) you will see that the fxml of the action-bar is included in each of them. If
you open the fxml files with Scene Builder you can see the action-bar included in the view.
