Computer Science: Object Oriented Programming
is pleased with your progress but now require a Graphical User Interface(GUI) for your application (to make it more modern). Create a ShipPane class that extends StackPane (javafx.scene.layout.StackPane).
This will act as the root node for your Scene. The ShipPane class will have the following components: • A MenuBar containing a MenuItem to open a FileChooser to select the file to open • A TitledPane control that provides an expandible container for Ship, including: – Properties of the Ship in a GridPane layout • A ListView control to hold and display the Messages data, including: – TitledPane to display each of the derived Message class objects – Each derived Message class i.e. SOSMessage, EncryptedMessage and NormalMes‐ sage object is placed inside its own GridPane (for layout of content) • You may use the following optional controls (or others that you find useful): – ScrollPane: Provides a scrollable container where necessary – HBox and VBox: Provide containers for horizontal and vertical stacking of nodes respectively (provided image) You are provided with a library file (from the last practical) that contains the Ship, Message, SOSMessage, NormalMessage and EncryptedMessage model classes. In addition, it includes a DataReader class with a readShipFile method that takes a File as a parameter and returns a Ship instance. The Ship class has a getMessages method that returns an array of Messages. You are also provided with a file named shipInfo.dat that you are required to read data from. Your Main class should contain the following: • Main must extend Application (javafx.application.Application), and you must implement the main method correctly • Implement the start method required by the JavaFX Application • In your main method, launch the JavaFX Application • Your class you will need to instantiate an instance of the ShipPane • Add the ShipPane instance to a Scene and load it onto the Stage provided by the Ap‐ plication and show the Stage
